Test Method
—
The capacitance shall be measured at 20°C with 1 ± 0.2kHz
(SL: 1 ± 0.2MHz) and 5V(r.m.s.) max.
Same condition as capacitance.
The insulation resistance shall be measured with 500 ± 50VDC within
60 ± 5 sec. of charging.
The capacitors shall not be damaged when DC voltage of 200% of the
rated voltage is applied between the lead wires for 1 to 5 sec.
(Charge/discharge current
≤50mA)
The capacitor is placed in the container with metal
balls of diameter 1mm so that each lead wire, short-
Approx. 2mm
circuited, is kept approximately 2mm off the balls as
shown in the figure, and DC voltage of 1.3kV is
applied for 1 to 5 sec. between capacitor lead wires
Metal balls
and small metals. (Charge/discharge current
≤50mA).
The capacitance measurement shall be made at each step specified in
table. Capacitance change from the value of step 3 shall not exceed the
limit specified.
