■Storage and Operation condition

1. The performance of chip multilayer ceramic capacitors may be affected by the storage conditions.

1-1. Store the capacitors in the following conditions:

Room Temperature of +5℃ to +40℃ and a Relative Humidity of 20% to 70%.

(1) High temperature and humidity conditions may accelerate the deterioration of solderability due to oxidation

　

of the terminal electrodes and deterioration of taping/packaging performance.

Therefore, maintain the appropriate storage temperature and humidity.

(2) Prolonged storage may cause oxidation of the electrodes and deterioration of the packaging materials.

If more than six months have elapsed since delivery, check the mounting before use.

If more than one year has elapsed since delivery, also check the solderability before use.

Even if the storage period is short, do not exceed the specified atmospheric conditions.

(3) Store the capacitors in the original packaging without opening the smallest packing unit.

Do not exceed the above atmospheric conditions for any length of time.

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 capacitor 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.
