Features

 

Pulse Withstanding Capacity

Operating Voltage=√(P*R) or Max. Operating Voltage listed above, whichever is lower.
Overload Voltage=2.5*√(P*R) or Max. Overload Voltage listed above, whichever is lower.
☑ Viking is capable of manufacturing the optional spec based on customer's requirement.

The single impulse graph is the result of 50 impulses of rectangular shape applied at one-minute intervals.

The limit of acceptance was a shift in resistance of less than 1% from the initial value. The power applied

was subject to the restrictions of the maximum permissible impulse voltage graph shown.

Continuous Pulse

The continuous load graph was obtained by applying repetitive rectangular pulses where the pulse period was adjusted so that the average power dissipated in the resistor was equal to its rated power at 70°C. Again the

limit of acceptance was a shift in resistance of less than 1% from the initial value.

Lightning Surge

Resistors are tested in accordance with IEC 60115-1 using both 1.2/50us and 10/700 pulse shapes. The limit of acceptance is a shift in resistance of less than 1% from the initial value.
