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.

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.
