Specifications
-25 to +105°C
Test Method
Operating Temperature Range
No visible defect, and dimensions are
within specified range.
The capacitor should be visually inspected for evidence of
defect. Dimensions should be measured with slide calipers.

Appearance and Dimensions
Marking
To be easily legible
The capacitor should be visually inspected.
The capacitor should not be damaged when DC12.6kV is
applied between the lead wires for 1 to 5 sec.
(Charge/Discharge currentV50mA)
Between Lead
Wires
No failure
The capacitor is placed in the container
with metal balls of diameter 1mm so that
each lead wire, short circuited, is kept
about 2.0mm off the metal balls as shown
in the figure at right, and DC voltage of
1.3kV is applied for 1 to 5 sec. between
capacitor lead wires and metal balls.

As shown in the figure at right, fix the body of
the capacitor and apply a tensile weight
gradually to each lead wire in the radial
direction of the capacitor up to 10N and keep
it for 10±1 sec.

Lead wire should not be cut off.
Capacitor should not be broken.

Strength of Lead
Each lead wire should be subjected to 5N of weight and bent
90° at the point of egress, in one direction, then returned to its
original position and bent 90° in the opposite direction at the
rate of one bend in 2 to 3 sec.
Bending
Appearance
No marked defect
The capacitor should be firmly soldered to the supporting lead
wire and vibrated at a frequency range of 10 to 55Hz, 1.5mm in
total amplitude, with about a 1-minute rate of vibration change
from 10Hz to 55Hz and back to 10Hz. Apply for a total of 6 hrs.,
2 hrs. each in 3 mutually perpendicular directions.

The lead wire of a capacitor should be dipped into a ethanol
solution of 25wt% rosin and then into molten solder for 2±0.5
sec. In both cases the depth of dipping is up to about 1.5 to
2.0mm from the root of lead wires.
Lead wire should be soldered with
