Aluminium-Housed 100 W Wire-Wound Resistor

Two aluminium-cased wire-wound resistors rated at 100 W and 0.33 Ω with 5 % tolerance. The aluminium housing acts as a heatsink, allowing sustained high-power dissipation without an external cooler. Each unit measures 59 mm body length and includes 2 mm solder pins plus a 3 mm mounting hole for secure PCB or chassis attachment.

Replaces Lower-Power Through-Hole Resistors

A 100 W rating replaces standard 1 W to 10 W axial resistors that overheat in continuous-duty circuits. The jump is worth it when the load demands prolonged dissipation above a few watts, such as LED driver ballasts, inverter snubbers or motor-speed control networks where smaller parts would drift or fail.

Suits High-Current LED And Power-Supply Builders

Designers needing stable 0.33 Ω loading in AC/DC converters, inverter stages or dynamic braking circuits will benefit. Not for buyers who need surface-mount components, higher resistance values, or sub-5 W dissipation where a smaller part saves board space.

Questions about this item

What are the mounting hole size and spacing for the aluminum case resistor?

The resistor body is 59 mm long with a 3 mm diameter anchoring hole that fits #2 screws or M2.3 nuts for secure mounting.

How do I solder the connections on this wirewound resistor?

Two rods with 2 mm holes are provided for soldering; insert the wire through each hole and solder for a reliable electrical connection.

What long-term checks should I perform on a 100 W aluminum housed resistor?

Periodically verify the mounting hardware remains tight and inspect the aluminum case for discoloration or damage that could indicate overheating.
