50 W 33 Ω chassis-mount wirewound resistor

This aluminium-housed wirewound resistor is rated at 33 Ω with a 50 W power rating and ±5 % tolerance. It is built for engineers, technicians and hobbyists who need a rugged, chassis-mounted load that can dissipate heat through a cooling plate in demanding environments.

Replaces lower-power or through-hole resistors

The 50 W rating and aluminium housing allow it to substitute smaller wirewound or film types that cannot handle sustained high-power loads or vibration. The upgrade is worth it when the application requires secure screw mounting, a 3.5 mm mounting hole and reliable operation in harsh conditions such as power supplies, transducers or elevator controls.

Check mounting space and thermal path before

Verify that the 49.8 × 27 × 15.5 mm body and 73.5 mm total length fit your chassis layout. Ensure a flat mounting surface with M3 hardware for the 3.5 mm hole so heat can transfer to the cooling plate. Confirm the 33 Ω value and 50 W rating match the circuit design; this pack contains two gold-tone resistors.
