The lead wire should be immersed into the melted solder of

350

±10°C up to about 1.5 to 2mm from the main body for

3.5

±0.5 sec.

Pre-treatment:

Capacitor should be stored at 125

±3°C for 1 hr., then placed

at room condition* for 24

±2 hrs. before initial measurements.

Post-treatment:

Capacitor should be stored for 24

±2 hrs. at room condition.*

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.

Solderability of Leads

Lead wire should be soldered with

uniform coating on the axial direction

over 3/4 of the circumferential direction.

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.

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

sec.

Strength of Lead

Pull

Lead wire should not be cut off.

Capacitor should not be broken.

Bending

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 capacitance measurement should be made at each step

specified in the Table.

Pre-treatment: Capacitor should be stored at 125

±3°C for 1 hr., then placed at

room condition* for 24

±2 hrs. before measurements.

Temperature Characteristics

The dissipation factor should be measured at 20

°C with

±0.2kHz and AC5V(r.m.s.) max.

Dissipation Factor (D.F.)

Char. R: 0.2% max.

The capacitor should not be damaged when DC voltage of

200% of the rated voltage (DC1 to 3.15kV) or DC voltage of

250% of the rated voltage (DC500V) is applied between the

lead wires for 1 to 5 sec.

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.

(Charge/Discharge current

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.
