Measurement Point
Test Voltage
Applied Time
Charge/discharge current : 50mA max.
Measurement Point : Between the terminations
Measurement Voltage : DC Rated Voltage
Charging Time
Charge/discharge current : 50mA max.
Measurement Temperature : Room Temperature
Measurement Temperature : Room Temperature
Capacitance
C≦1000pF
at each specified temp. stage.
Capacitance value as a reference is the value in step 3.
The capacitance drift is calculated by dividing the differences
between the maximum and minimum measured values in the
step 1,3 and 5 by the cap. value in step 3.
