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.
