Aluminium-housed wirewound resistor kit

Two 100 W 0.3 Ω wirewound resistors in aluminium cases suit engineers and hobbyists who need reliable power dissipation in LED replacement, converter or motor-speed-control circuits. Each unit carries a 5 % tolerance for consistent performance across builds.

Build integration and mounting

The 59 mm body length and 2.32 in board length let the resistor sit on standard PCBs, while 2 mm soldering rods and a 3.2 mm antisymmetric anchoring hole accept #2 screws or M2.3 nuts for secure mechanical fixing. The aluminium housing removes the need for a separate heatsink in many layouts.

Thermal behaviour and power handling

Rated at 100 W, the resistor uses the aluminium case to conduct heat away from the wound element, maintaining stability during continuous operation. The compact structure and qualified copper, nickel and aluminium construction support overload capability without forced-air cooling in typical applications.

Questions about this item

At what temperature does the 100 W aluminium housing reach its thermal limit under continuous load?

The aluminium case is designed to dissipate heat from the wire-wound element, but no specific thermal-limit temperature is published for this 100 W resistor.

How much noise or heat does the resistor produce when running at full power all day?

As a passive wire-wound component it generates no audible noise; the aluminium housing radiates the 100 W of heat, so adequate airflow or a heatsink is required for continuous operation.

What mounting hardware must I already have to secure the 59 mm resistor body?

You will need two #2 screws or M2.3 nuts to fit the 3.2 mm anchoring holes, plus solder or connectors for the two 2 mm terminal holes.
