Bending: (Test Ub)

Performance:

While a load of 500g applied to the lead wire, the body of the capacitor shall bent 90˚ and returned to

the original posi�on. This opera�on shall be conducted in a few seconds. Then the body shall be bent

90˚ in the opposite direc�on and returned to the original posi�on.

There shall be no such mechanical damage as terminal damage, etc.

MECHANICAL CHARACTERISTICS

Terminal strength (Tes�ng method IEC 68-2-21)

Tensile: (Test UaI)

A load of 10N (1.0kg) shall be gradually applied to the terminal in the axial direc�on and held thus for

10 seconds.

Rapid change of temperature. (Tes�ng method IEC 68-2-21)

ELECTRICAL CHARACTERISTICS (continued)

The test capacitor shall be kept in the tes�ng oven and be kept at condi�ons of the following table, and it shall be repeated for 5 cycles

successfully. A�er the test, the capacitor shall be le� alone at the ordinary condi�ons for 2 hours.

Test condi�ons:

20˚C ±5˚C

1 minute

100 Vdc

Test voltage between terminals:

Dielectric strength:

Between terminal and enclosure

Method of the test as described below:

Put the 1mm diameter of small metallic balls in a vessel.

Performance:

The test capacitor shall be submerged with the small metallic balls. Distance of the metallic balls and the terminals shall be kept about

The test voltage shall be applied between the short-circuited terminals and the metallic balls

There should be no dielectric breakdown or other damage

Performance:

1.6 x Vg applied for 2 sec, at 20˚C ±5˚C (cut off current 10mA)

There shall be no dielectric breakdown or other damage.

Apply 200% of rated voltage between terminals and enclosure for 2 to 5 seconds.
