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.

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.
