The capacitor should be visually inspected for evidence of
defect. Dimensions should be measured with slide calipers.
The capacitor should be visually inspected.
The capacitor should 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 currentV50mA)
The capacitor is placed in the container with
metal balls of diameter 1mm so that each
lead wire, short circuited, is kept about 2mm
off the metal balls as shown in the figure at
right, and AC1250V(r.m.s.) <50/60Hz> is
applied for 1 to 5 sec. between capacitor
lead wires and metal balls.

The insulation resistance should be measured with
DC500±50V within 60±5 sec. of charging.
The capacitance should be measured at 20°C with 1±0.2MHz
and AC5V(r.m.s.) max.
The Q should be measured at 20°C with 1±0.2MHz and
AC5V(r.m.s.) max.
The capacitance measurement should be made at each step
specified in Table.

9 Strength of Lead
Bending
Lead wire should not be cut off.
Capacitor should not be broken.
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 (5N for
lead diameter 0.5mm), and keep it for 10±1
W
sec.
Each lead wire should be subjected to 5N (2.5N for lead
diameter 0.5mm) 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.

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.
11 Solderability of Leads
Lead wire should be soldered with
uniform coating on the axial direction
over 3/4 of the circumferential direction.
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
2mm from the root of lead wires.

The lead wire should be immersed into the melted solder of
350±10°C (Body of ø5mm and under: 270±5°C) up to about 1.5
to 2mm from the main body for 3.5±0.5 sec.
(Body of ø5mm and under: 5±0.5 sec.)
Post-treatment:
Capacitor should be stored for 1 to 2 hrs. at room condition*¹.
*¹ "room condition" Temperature: 15 to 35°C, Relative humidity: 45 to 75%, Atmospheric pressure: 86 to 106kPa
*² "C" expresses nominal capacitance value (pF).
