Test Method
Add and measure the DC Voltage gradually
Maxto get the discharge threshold voltage.
The measuring current is 1mA/1 second max.(1sec).(1mA)
Measure the insulation resistance of two end of
leadwire under the specified DC voltage.
Capacitance C(pF)
Electrostatic Capacitance under the test condition
of 1KHz,DC 6V(max).
Specification
It depands on each spec.
100MΩ min.
0.8pF max.
