Stackpole MWW Molded Wirewound Resistors

Stackpole MWW wirewound resistors use completely molded construction with welded terminations and tinned copper axial leads for through-hole mounting. Compare resistance, tolerance, and power ratings at both 125 °C and 70 °C.

Power ratings depend on temperature: MWW1 is 1 W at 125 °C and 1.3 W at 70 °C; MWW3 is 3 W and 3.2 W; MWW5 is 5 W and 5.5 W; MWW10 is 10 W and 11 W. Parts outside the standard resistance ranges retain their ordering-code values, with unverified TCR left blank. Consult Stackpole for these options and the datasheet for derating.
