The lead wire of a capacitor should be dipped into molten
solder for 2
±0.5 sec.
The depth of immersion is up to about 1.5 to 2.0mm from the
root of lead wires.

Solderability of Leads
Lead wire should be soldered with uniform coating
on the axial direction over 3/4 of the circumferential
direction.
As in Figure 1, discharge is made 50 times at 5 sec. intervals
from the capacitor (Cd) charged at DC voltage of specified.

First, the terminals of the capacitor should be connected
together. Then, as shown in the figure at right,
the capacitor should be immersed
into 10% salt solution up to a position
of about 3 to 4mm apart from the
terminals.
Finally, AC1500V(r.m.s.) is applied
for 60 sec. between the capacitor lead
wires and electrode plate.
The insulation resistance should be measured with
DC500
±50V within 60±5 sec. of charging.

Dissipation Factor
(D.F.)
The capacitance should be measured at 20˚C with 1
±0.1kHz
and AC5V(r.m.s.) max.

Capacitance
Within specified tolerance
The capacitor should be visually inspected.

Marking
To be easily legible
The capacitor should be visually inspected for evidence of
defect.
Dimensions should be measured with slide calipers.
