Even if the storage period is short, do not exceed the specified atmospheric conditions.
1-2. Corrosive gas can react with the termination (external) electrodes or lead wires of capacitors, and result
in poor solderability. Do not store the capacitors in an atmosphere consisting of corrosive gas (e.g.,hydrogen
sulfide, sulfur dioxide, chlorine, ammonia gas etc.).
1-3. Due to moisture condensation caused by rapid humidity changes, or the photochemical change caused
by direct sunlight on the terminal electrodes and/or the resin/epoxy coatings, the solderability and
electrical performance may deteriorate. Do not store capacitors under direct sunlight or in high huimidity
conditions
■Rating
1.Temperature Dependent Characteristics
1. The electrical characteristics of the capacitor can change with temperature.
1-1. For capacitors having larger temperature dependency, the capacitance may change with temperature
changes. The following actions are recommended in order to ensure suitable capacitance values.
(1) Select a suitable capacitance for the operating temperature range.
(2) The capacitance may change within the rated temperature.
When you use a high dielectric constant type capacitors in a circuit that needs a tight (narrow) capacitance
tolerance (e.g., a time-constant circuit), please carefully consider the temperature characteristics, and
carefully confirm the various characteristics in actual use conditions and the actual system.

2.Measurement of Capacitance
1. Measure capacitance with the voltage and frequency specified in the product specifications.
1-1. The output voltage of the measuring equipment may decrease occasionally when capacitance is high.
Please confirm whether a prescribed measured voltage is impressed to the capacitor.
1-2. The capacitance values of high dielectric constant type capacitors change depending on the AC voltage applied.
Please consider the AC voltage characteristics when selecting a capacitor to be used in a AC circuit.
3.Applied Voltage
1. Do not apply a voltage to the capacitor that exceeds the rated voltage as called out in the specifications.
1-1. Applied voltage between the terminals of a capacitor shall be less than or equal to the rated voltage.
(1) When AC voltage is superimposed on DC voltage, the zero-to-peak voltage shall not exceed the rated DC voltage.
When AC voltage or pulse voltage is applied, the peak-to-peak voltage shall not exceed the rated DC voltage.
(2) Abnormal voltages (surge voltage, static electricity, pulse voltage, etc.) shall not exceed the rated DC voltage.
Typical voltage applied to the DC capacitor
DC voltage DC voltage+AC AC voltage Pulse voltage
(E：Maximum possible applied voltage.)
1-2. Influence of over voltage
Over voltage that is applied to the capacitor may result in an electrical short circuit caused by the breakdown
of the internal dielectric layers .
The time duration until breakdown depends on the applied voltage and the ambient temperature.
4.Type of Applied Voltage and Self-heating Temperature
1.Confirm the operating conditions to make sure that nolarge current is flowing into the capacitor due to the
continuous application of an AC voltage or pulse voltage.
When a DC rated voltage product is used in an AC voltage circuit or a pulse voltage circuit, the AC current
or pulse current will flow into the capacitor; therefore check the self-heating condition.
Please confirm the surface temperature of the capacitor so that the temperature remains within the upper limits
of the operating temperature, including the rise in temperature due to self-heating. When the capacitor is
used with a high-frequency voltage or pulse voltage, heat may be generated by dielectric loss.
<Applicable to Rated Voltage of less than 100VDC>
1-1. The load should be contained to the level
such that when measuring at atmospheric
temperature of 25°C, the product's self-heating
remains below 20°C and the surface
temperature of the capacitor in the actual circuit
remains within the maximum operating
temperature.

5. DC Voltage and AC Voltage Characteristic
1. The capacitance value of a high dielectric constant type
capacitor changes depending on the DC voltage applied.
Please consider the DC voltage characteristics when a
capacitor is selected for use in a DC circuit.
1-1. The capacitance of ceramic capacitors may change
sharply depending on the applied voltage. (See figure)
Please confirm the following in order to secure the
capacitance.
(1) Determine whether the capacitance change caused
by the applied voltage is within the allowed range .
(2) In the DC voltage characteristics, the rate of
capacitance change becomes larger as voltage
increases, even if the applied voltage is below
the rated voltage. When a high dielectric constant
type capacitor is used in a circuit that requires a
tight (narrow) capacitance tolerance (e.g., a time
constant circuit), please carefully consider the
voltage characteristics, and confirm the various
characteristics in actual operating conditions in
an actual system.
2. The capacitance values of high dielectric
constant type capacitors changes depending
on the AC voltage applied.
Please consider the AC voltage characteristics
when selecting a capacitor to be used in a
AC circuit.
6. Capacitance Aging
[Example of Change Over Time (Aging characteristics) ]
1. The high dielectric constant type capacitors
have the characteristic in which the capacitance
value decreases with the passage of time.
When you use a high dielectric constant type
capacitors in a circuit that needs a tight (narrow)
capacitance tolerance (e.g., a time-constant circuit),
please carefully consider the characteristics
of these capacitors, such as their aging, voltage,
and temperature characteristics. In addition,
check capacitors using your actual appliances
at the intended environment and operating conditions.
7.Vibration and Shock
1. Please confirm the kind of vibration and/or shock, its condition, and any generation of resonance.
Please mount the capacitor so as not to generate resonance, and do not allow any impact on the terminals.
2. Mechanical shock due to being dropped may cause damage or
a crack in the dielectric material of the capacitor.
Do not use a fallen capacitor because the quality and reliability
may be deteriorated.
3. When printed circuit boards are piled up or handled, the corner
of another printed circuit board
should not be allowed to hit the capacitor in order to avoid
a crack or other damage to the capacitor.

■Soldering and Mounting
1.Mounting Position
1. Confirm the best mounting position and direction that minimizes the stress imposed on the capacitor during flexing
or bending the printed circuit board.
1-1.Choose a mounting position that minimizes the stress imposed on the chip during flexing or bending of the board.
[Component Direction]
Locate chip horizontal to the
direction in which stress acts.
[Chip Mounting Close to Board Separation Point]
It is effective to implement the following measures, to reduce stress in separating the board.
It is best to implement all of the following three measures; however, implement as many measures as possible
to reduce stress.
Stress Level
(1) Turn the mounting direction of the component parallel to the board separation surface.
A > D
(2) Add slits in the board separation part.
A > B
(3) Keep the mounting position of the component away from the board separation surface.
A > C
[Mounting Capacitors Near Screw Holes]
When a capacitor is mounted near a screw hole, it may be affected by the board deflection that occurs during
the tightening of the screw. Mount the capacitor in a position as far away from the screw holes as possible.
2.Information before Mounting
1. Do not re-use capacitors that were removed from the equipment.
2. Confirm capacitance characteristics under actual applied voltage.
3. Confirm the mechanical stress under actual process and equipment use.
4. Confirm the rated capacitance, rated voltage and other electrical characteristics before assembly.
5. Prior to use, confirm the solderability for the capacitors that were in long-term storage.
6. Prior to measuring capacitance, carry out a heat treatment for capacitors that were in long-term storage.
7.The use of Sn-Zn based solder will deteriorate the reliability of the MLCC.
Please contact our sales representative or product engineers on the use of Sn-Zn based solder in advance.

3.Maintenance of the Mounting (pick and place) Machine
1. Make sure that the following excessive forces are not applied to the capacitors.
1-1. In mounting the capacitors on the printed circuit board, any bending force against them shall be kept
to prevent them from any bending damage or cracking. Please take into account the following precautions
and recommendations for use in your process.
(1) Adjust the lowest position of the pickup nozzle so as not to bend the printed circuit board.
(2) Adjust the nozzle pressure within a static load of 1N to 3N during mounting.
[Incorrect]
[Correct]
2.Dirt particles and dust accumulated between the suction nozzle and the cylinder inner wall prevent
the nozzle from moving smoothly. This imposes greater force upon the chip during mounting,
causing cracked chips. Also, the locating claw, when worn out, imposes uneven forces on the chip
when positioning, causing cracked chips. The suction nozzle and the locating claw must be maintained,
checked and replaced periodically.

4-1.Reflow Soldering
1. When sudden heat is applied to the components, the [Standard Conditions for Reflow Soldering]
mechanical strength of the components will decrease
because a sudden temperature change causes
deformation inside the components. In order to prevent
mechanical damage to the components, preheating is
required for both the components and the PCB.
Preheating conditions are shown in table 1. It is required to
keep the temperature differential between the solder and

2. When sudden heat is applied to the components, the
mechanical strength of the components will decrease
because a sudden temperature change causes
deformation inside the components. In order to prevent
mechanical damage to the components, preheating is
required for both of the components and the PCB.

4-3.Correction of Soldered Portion
When sudden heat is applied to the capacitor, distortion caused by the large temperature difference occurs internally,
and can be the cause of cracks. Capacitors also tend to be affected by mechanical and thermal stress depending
on the board preheating temperature or the soldering fillet shape, and can be the cause of cracks.
Please refer to "1. PCB Design" or "3. Optimum solder amount" for the solder amount and the fillet shapes.
1. Correction with a Soldering Iron
1-1. In order to reduce damage to the capacitor, be sure to preheat the capacitor and the mounting board.
Preheat to the temperature range shown in Table 3. A hot plate, hot air type preheater, etc. can be used for preheating.
1-2. After soldering, do not allow the component/PCB to cool down rapidly.
1-3. Perform the corrections with a soldering iron as quickly as possible. If the soldering iron is applied too long,
there is a possibility of causing solder leaching on the terminal electrodes, which will cause deterioration of the
adhesive strength and other problems.
Table 3
Lead Free Solder: Sn-3.0Ag-0.5Cu
2. Correction with Spot Heater
Compared to local heating with a soldering iron, hot air heating by a spot heater heats the overall component
and board, therefore, it tends to lessen the thermal shock. In the case of a high density mounted board,
a spot heater can also prevent concerns of the soldering iron making direct contact with the component.
2-1. If the distance from the hot air outlet of the spot heater to the component is too close, cracks may occur due to
thermal shock. To prevent this problem, follow the conditions shown in Table 4.
2-2. In order to create an appropriate solder fillet shape, it is recommended that hot air be applied at the angle shown
in Figure 1.

Distance 5mm or more
Hot Air Application angle 45° *Figure 1

Application Time (1206 (in inch) / (3216 (in mm) size or smaller)
Less than 30 seconds
(1210 (in inch) / 3225 (in mm) size or larger)
3. Optimum solder amount when re-working with a soldering iron
3-1. In the case of 0603 (in inch) / 1608 (in mm) and smaller
sizes (GRM03/15/18), the top of the solder fillet should
be lower than 2/3 of the thickness of the component or
0.5mm, whichever is smaller.
In the case of 0805 (in inch) / 2012(in mm) and larger
sizes (GRM21/31/32/43/55), the top of the solder fillet in section
should be lower than 2/3 of the thickness of the component.
If the solder amount is excessive, the risk of cracking is higher
during board bending or under any other stressful condition.
3-2. A soldering iron with a tip of ø3mm or smaller should be used.
It is also necessary to keep the soldering iron from touching
the components during the re-work.
3-3. Solder wire with ø0.5mm or smaller is required for soldering.

5.Washing
Excessive ultrasonic oscillation during cleaning can cause the PCBs to resonate, resulting in cracked chips
or broken solder joints. Take note not to vibrate PCBs.
6.Electrical Test on Printed Circuit Board
1. Confirm position of the backup pin or specific jig, when inspecting the electrical performance of a
capacitor after mounting on the printed circuit board.
1-1. Avoid bending the printed circuit board by the pressure of a test-probe, etc.
The thrusting force of the test probe can flex the PCB, resulting in cracked chips or open solder
joints. Provide backup pins on the back side of the PCB to prevent warping or flexing.
Install backup pins as close to the test-probe as possible.
1-2. Avoid vibration of the board by shock when a test -probe contacts a printed circuit board.
[Not Recommended] [Recommended]
7.Printed Circuit Board Cropping
1. After mounting a capacitor on a printed circuit board, do not apply any stress to the capacitor that
caused bending or twisting the board.
1-1. In cropping the board, the stress as shown at right may cause the capacitor to crack.
Cracked capacitors may cause deterioration of the insulation resistance, and result in a short.
Avoid this type of stress to a capacitor.
[Bending] [Twisting]
2. Check the cropping method for the printed circuit board in advance.
2-1. Printed circuit board cropping shall be carried out by using a jig or an apparatus (Disk separator, router
type separator, etc.) to prevent the mechanical stress that can occur to the board.
* When a board separation jig or disk separator is used, if the following precautions are not observed,
a large board deflection stress will occur and the capacitors may crack.
Use router type separator if at all possible.
