Riedon’s pulse rating assumptions are based on a single pulse of 10mS or less, with no energy absorbed by the coating material or core, and the resistance material temperature is 25ºC before the pulse and 450ºC after the pulse. Riedon does not publish transient or pulse data for the catalog resistors, but can usually meet or exceed the published ratings of other suppliers and provide an optimum pulse rated resistor for a specific application.
