Stackpole SP Fusing Wirewound Resistors

Stackpole SP fusing wirewound resistors use a high-temperature silicone coating, welded terminations, and tinned copper leads. All listed SP3A parts share through-hole mounting, ±5% tolerance, a 4 W rating at 25 °C, and a ±20 ppm/°C temperature coefficient. Compare resistance values below.

The operating temperature range is −55 to +350 °C, with power derating required at elevated temperature. The 4 W rating describes normal operation at 25 °C, not fusing power. Consult the datasheet for fusing behavior, voltage limits, and mounting requirements.
