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.

The capacitance measurement should be made at each step

specified in Table 3.

The capacitor should not be damaged when the test voltages

from Table 1 are applied between the lead wires for 60 sec.

First, the terminals of the capacitor

should be connected together. Then,

as shown in the figure at right, a metal

foil should be closely wrapped around

the body of the capacitor to the

distance of about 3 to 6mm from

each terminal.

Then, the capacitor should be inserted

into a container filled with metal balls

of about 1mm diameter. Finally, AC

voltage from Table 2 is applied for 60 sec. between the

capacitor lead wires and metal balls.

<Table 2>

The insulation resistance should be measured with

DC500

±50V within 60±5 sec. of charging.

The voltage should be applied to the capacitor through a

resistor of 1M

Ω.

The capacitance, dissipation factor and Q should be measured

at 20˚C with 1

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.
