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.
2.Use a safety standard certified capacitor in a power supply input circuit (AC filter), as it is also
necessary to consider the withstand voltage and impulse withstand voltage defined for each device.
4.Type of Applied Voltage and Self-heating Temperature
1.Confirm the operating conditions to make sure that no
large 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
1. The high dielectric constant type capacitors
[Example of Change Over Time (Aging characteristics) ]
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.

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 a minimum 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 Reflow
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
the components surface (ΔT) as small as possible.
2. Solderability of tin plating termination chips might be
deteriorated when a low temperature soldering profile where
the peak solder temperature is below the melting point of Temperature
tin is used. Please confirm the solderability of tin plated Incase of Lead Free Solder
termination chips before use. ( ): In case of Pb-Sn Solder
3. When components are immersed in solvent after mounting, Vapor Reflow
be sure to maintain the temperature difference (ΔT)
between the component and the solvent within the range

4-1. Overly thick application of solder paste results in
a excessive solder fillet height.
This makes the chip more susceptible to mechanical
and thermal stress on the board and may cause
the chips to crack.
4-2. Too little solder paste results in a lack of adhesive
strength on the outer electrode, which may result in in section
chips breaking loose from the PCB.
4-3. Make sure the solder has been applied smoothly to the end surface to a height of 0.2mm min.
Make sure not to impose any abnormal mechanical shocks to the PCB.

4-2.Flow Soldering
1. Do not apply flow soldering to chips not listed in Table 2. [Standard Conditions for Flow Soldering]
Table 2 Temperature Differential
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. [Allowable Flow Soldering Temperature and Time]
Preheating conditions are shown in table 2. It is required to
keep the temperature differential between the solder and
the components surface (ΔT) as low as possible.
3. Excessively long soldering time or high soldering
temperature can result in leaching of the outer electrodes,
causing poor adhesion or a reduction in capacitance value
due to loss of contact between the electrodes and end termination.
4. When components are immersed in solvent after mounting,
be sure to maintain the temperature differential (ΔT) In the case of repeated soldering, the accumulated
between the component and solvent within the range soldering time must be within the range shown above.

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 2. 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
*Applicable for both Pb-Sn and Lead Free Solder.
Pb-Sn Solder: Sn-37Pb
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 3.

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 (GQM15/18), 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 in section
sizes (GQM21/22), the top of the solder fillet
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 capacitor as possible.
1-2. Avoid vibration of the board by shock when a test -probe contacts a printed circuit board.

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.
(1) Example of a suitable jig
[In the case of Single-side Mounting]
An outline of the board separation jig is shown as follows.
Recommended example: Stress on the component mounting position can be minimized by holding the
portion close to the jig, and bend in the direction towards the side where the capacitors are mounted.
Not recommended example: The risk of cracks occurring in the capacitors increases due to large stress
being applied to the component mounting position, if the portion away from the jig is held and bent in the
direction opposite the side where the capacitors are mounted.
