Pull test

External

appearance

Lead wire should not be cut off,

capacitor should not be broken.

As a figure, fix the body of capacitor,

apply a tensile weight gradually to each

lead wire in the radial direction of

capacitor up to 20 N, and keep it for



10 s ± 1 s.

Bending test

External

appearance

Lead wire should not be cut off,

capacitor should not be broken.

Bending each lead wire to 90° from the

lead egress with 2.5 N force, then back to

original position and bent again from the

same direction.



Totally 3 bends, 3 s each time.



1 bend: bending to 90° the return to

normal position is one bend.



Start from 1.6 mm to 3.2 mm from the



part body.
