Aluminium-Housed 100 W Wirewound Resistor

This two-piece set supplies 100 W, 4 Ω wirewound resistors in aluminium cases. They suit LED replacement converters, AC/DC circuits, inverters, motor-speed controls and driver boards where stable power dissipation is required. Each unit offers a 5 % tolerance for consistent circuit behaviour.

Verify Voltage, Current and Mounting Space

Confirm that your circuit never exceeds the 100 W rating at 4 Ω before installation. The body measures 59 mm long with a 3.2 mm mounting hole for M2.3 or #2 screws, so check available board area and screw clearance. Two 2 mm solder rods provide the electrical connection points.

Aluminium Case Dissipates Heat Without a Fan

The aluminium housing acts as the heatsink, eliminating the need for forced airflow in most enclosed builds. Qualified copper, nickel and aluminium construction gives overload capability within a compact structure. Direct chassis mounting through the 3.2 mm hole improves thermal transfer and mechanical security.

Questions about this item

What comes in the package and is any mounting hardware included?

The package contains two aluminum-housed 100 W 4 Ω wire-wound resistors. Each unit has a 3.2 mm mounting hole that accepts #2 screws or M2.3 nuts, but screws and nuts are not supplied.

How do I decide between different power or resistance options for this part?

This listing is fixed at 100 W and 4 Ω with 5 % tolerance; no other power ratings or resistance values are offered for this model.

Will the 100 W rating hold up when the resistor is installed on a typical PCB?

The 100 W rating assumes the aluminum case is properly bolted to a heatsink; without adequate mounting the safe dissipation drops well below 100 W.
