! Caution

■Limitation of Applications

Please contact us before using our products for the applications listed below which require especially high reliability

　 for the prevention of defects which might directly cause damage to the third party's life, body or property.

　　　①Aircraft equipment ②Aerospace equipment ③Undersea equipment ④Power plant control equipment

　　　⑤Medical equipment ⑥Transportation equipment(vehicles,trains,ships,etc.) ⑦Traffic signal equipment

　　　⑧Disaster prevention / crime prevention equipment ⑨Data-processing equipment

　　　⑩Application of similar complexity and/or reliability requirements to the applications listed in the above.

■Storage and Operation condition

1. The performance of chip monolithic 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) Sunlight, dust, rapid temperature changes, corrosive gas atmosphere, or high temperature and humidity

　

conditions during storage may affect solderability and packaging performance.

Therefore, please maintain the storage temperature and humidity. Use the product within six months,

as prolonged storage may cause oxidation of the terminations (outer electrodes).

(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 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.
