Surge withstand capability

Surge life test

In the glass tube ends in 8/20 us surge tester, applying the model that

corresponds to the impact resistance current, time interval for the

60 s of plus or minus the test 5 times. Test the dc voltage,

insulation resistance, static capacitance and check the appearance.

Apply 10KV voltage charged in 1500pF condenser and

apply the current to the specimen,200 times at 10

seconds of intervals.

Bend the lead wire, with jig which radius is 0.75~0.8mm, at the point

of 2mm from the body, under 0.25 kgs load applied at the right angle

the direction of theamis and get the bent lead wire back to its

original poing after the procedure was repeated 2times.

Apply flux and immerse in molten solder, up to the point of

3mm from the body,for 5 sec. (235

). Wash

the leadwire and check for soldering adhesion.

Lead wire is evenly covered by

solder over 90%.
