Test Methods And Results

Test Item

Test Method

Specification

DC Spark-over

Voltage Vs(V)

Add and measure the DC Voltage gradually Maxto get the discharge threshold

voltage. The measuring current is 1mA/1 second max.

It depands on each spec.

Insulation

Resistance

Measure the insulation resistance of two end of leadwire under the specified DC

voltage.

100M

Ω min.

Capacitance Cj(pF)

Measure the Electrostatic Capacitance under the test condition of 1KHz,DC

6V(max).

1pF max.

Life(JSE)

Apply a standard impulse voltage (8X20

μsec)of 100A for 5 times with intervals of 30

sec., and then change the polarity of the surge and apply a impulse again. Then

measure DC spark-over voltage, IR & Capacitance.

DC spark-over voltage

JSE:∣△ Vs/Vs ∣

≤30%

Life(JSE)

Apply 10 KV voltage charged in 1500pF condenser and apply the current to the

specimen,200 times at 10 seconds of intervals

Insulation Resistance &

Capacitance to meet the

specified value. Appearance:

No cracks or failures.

Cold Resistance

Measurement after -40℃ /1000 HRS & normal temperature/2 HRS.

Features are conformed to

rated spec.

Heat Resistance

Measurement after 125℃ /1000 HRS & normal temperature/2 HRS.

Humidity Resistance

Measurement after humidity 90~95 ℃ (45 ℃ ) /1000 HRS & normal

temperature/2 HRS.

Temperature Cycle

10 times repetition of cycle -40 ℃ /30min

→normal, temp/2 min →125℃ /30min,

measurement after normal temp/2 HRS.

Pull Strength

Apply 0.5kg load for 10sec.

Lead shall not pull out to snap.

Flexural Strength

Bend lead wire at the point of 2mm from body under 0.25 load and back to its

original point. Repeat 1 time.
