Testing Method
—
The capacitance should be measured at 20°C with 1±0.2kHz
and AC 5V(r.m.s.) max.
Same condition as capacitance.
The insulation resistance should be measured with DC1000V
within 60±5 sec. of charging.
The capacitor should not be damaged when DC voltage of
150% of the rated voltage is applied between the lead wires for
60±5 sec. in insulating liquid or gas.
(Charge/Discharge currentV50mA)
The capacitor is placed in the container with
metal balls of diameter 1mm so that each
lead wire, shortcircuited, is kept
approximately 2mm off the metal balls as
shown in the figure at right, and DC voltage
of 3kV is applied for 10 sec. between
capacitor lead wires and metal balls.
(Charge/Discharge currentV50mA)
Approx. 2mm
Metal balls
The capacitance measurement should be made at each step
specified in table.
Capacitance change from the value of step 3 should not
exceed the limit specified.

The lead wires should be immersed into the melted solder of
350±10˚C up to about 1.5 to 2.0mm from the main body for
3.5±0.5 sec.
Post-treatment: Capacitor should be stored for 24±2 hrs. at
*room condition.
Set the capacitor for 240±8 hrs. at 40±2˚C in 90 to 95% relative
humidity.
Post-treatment: Capacitor should be stored for 1 to 2 hrs. at
*room condition.
Apply a DC voltage of 125% of the rated voltage for 1000+-048
hrs. in silicon oil at 85±2˚C.
Post-treatment: Capacitor should be stored for 24±2 hrs. at
*room condition.

Dielectric Strength
(Between

No failure
(Note) Tests for Dielectric Strength (between lead wires), Charge Discharge Test, Humidity, Temperature Cycle and Life should be performed with
specimens having molded resin (MR1023C : made by Murata) extending over 3mm on all the surface.
* "room condition" Temperature: 15 to 35D, Relative humidity: 45 to 75%, Atmospheric pressure: 86 to 106kPa
