Appearance and Dimensions

No visible defect, and dimensions are

within specified range.

To be easily legible

The capacitor should be visually inspected for evidence of

defect.

Dimensions should be measured with slide calipers.

Marking

The capacitor should be visually inspected.

No failure

No failure

The capacitor should not be damaged when DC voltage of

200% of the rated voltage (DC1kV) or DC voltage of 250% of

the rated voltage (DC500V) is applied between the lead wires

for 1 to 5 sec.

(Charge/Discharge current

V50mA)

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

V50mA)

Insulation

Resistance (I.R.)

The insulation resistance should be measured with

DC500±50V within 60±5 sec. of charging.

Capacitance

The capacitance should be measured at 20°C with 1±0.2kHz

and AC5V(r.m.s.) max.

Within specified tolerance

0.3% max.

The dissipation factor should be measured at 20°C with

1±0.2kHz and AC5V(r.m.s.) max.

8

Temperature Characteristics

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.

9

Strength of Lead

Pull

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 and keep

it for 10±1 sec.

Bending

Each lead wire should be subjected to 5N 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.

10

Vibration

Resistance

Appearance

No marked defect

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.

Per item 4.

The lead wire should be immersed into the melted solder of

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.*
