Stackpole WWF General Purpose Fusing Wirewound Resistors

Stackpole WWF axial wirewound resistors combine normal resistive operation with fusing behavior under sustained overload. The listed parts use through-hole mounting and ±5% tolerance. Compare resistance and power ratings at 25 °C and 70 °C to select the appropriate type. The series uses a high-temperature silicone coating.

The table shows normal power ratings, not fusing power. Fusing time depends on applied overload and must be checked against the datasheet for the intended circuit. Consult the datasheet for resistance-dependent applicability, temperature coefficient, voltage limits, and derating. Non-standard resistance values require confirmation of the applicable characteristics.
