■Storage and Operation condition
1. The performance of chip monolithic ceramic capacitors may be affected by the storage conditions.
1-1. Store capacitors in the following conditions: Temperature of +5℃to +40℃and a Relative Humidity
of 20% to 70%.
(1) Sunlight, dust, rapid temperature changes, corrosive gas atmosphere or high temperature and humidity
conditions during storage may affect the solderability and the packaging performance
Please use product within six months of receipt.
(2) Please confirm solderability before using after six months.
Store the capacitors without opening the original bag.
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 insure 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.
Example: a time constant circuit., please carefully consider the characteristics of these capacitors,
such as their aging, voltage, and temperature characteristics.
And check capacitors using your actual appliances at the intended environment and operating conditions.

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

1-2. Influence of overvoltage
Overvoltage 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. Applied Voltage and Self-heating Temperature
1. When the capacitor is used in a high-frequency voltage, pulse voltage, application,
be sure to take into account self-heating may be caused by resistant factors of the capacitor.
1-1.The load should be contained to the level such that when measuring at atomospheric temperature
of 25℃,the product's self-heating remains below 20℃and surface temperature of the capacitor in the
actual circuit remains wiyhin the maximum operating temperature.
