MOMENTARY OVERLOAD

1. Momentary overload (> 2 s):

See example in table below. In all cases, it should be understood that:

- The 12 Pn overload applies only to ohmic values 0.1.

- The overload voltage shall not be higher than that used for the dielectric strength test (see Standard Electrical Specifications).

2. Short time overload (< 2 s):

For times shorter than 2 s, higher overloads can be sustained in some cases. Consult Vishay Sfernice.
