Insulation Resistance
Voltage proof
Impedance ratio ZT/Z20(MAX.)
The insulation resistance shall be more than 100MΩ at DC 500V application between terminal and bracket.
There is no abnormality during AC 2500V 1 minute's application between terminal and bracket.
The specifications listed at right shall be met when the capacitors are restored
to 20°C after D.C. bias plus rated ripple current is applied for 5000 hours at
85°C, the peak voltage shall not exceed the rated voltage.
After storing the capacitors under no load at 85°C for 1000 hours and
then performing voltage treatment based on JIS C 5101-4 clause 4.1
at 20°C, they shall meet the reguirements listed at right.
