Aluminium-Housed Wire-Wound Resistor

This 100 W wire-wound resistor uses an aluminium case to dissipate heat without an insulated cover that would trap it. The construction combines copper, nickel and aluminium in a compact body rated for overload capability. It is intended for engineers and hobbyists who need a stable 0.3 Ω load in power circuits.

Suits DC converters, inverters

The part fits applications such as LED driver correction, AC/DC converters, inverters and motor-speed controllers where a 100 W, 5 % tolerance resistor is specified. Builds requiring a different resistance value, a higher power rating or a surface-mount package should look at other components.

0.3 Ω at 100 W in a 59 mm aluminium body

The single deciding specification is the 0.3 Ω resistance combined with a 100 W power rating housed in a 59 mm long aluminium case with 2 mm solder rods and a 3.2 mm mounting hole. If your design calls for that exact resistance and power level, this resistor matches the requirement.

Questions about this item

Does the 100 W 0.3 Ω resistor ship with mounting hardware or only the aluminum-cased body?

Only the resistor body is supplied; two 2 mm solder rods and a 3.2 mm anchoring hole for M2.3 or #2 screws are built in, so you provide your own fasteners.

I see a single 0.3 Ω 100 W variant — are other resistance or power options available on this listing?

This listing covers only the 0.3 Ω 100 W wire-wound model; different ohm values or wattages would be separate items.

Will the 59 mm aluminum case dissipate the full 100 W without an extra heatsink in a typical LED driver?

The case is designed as the primary heat path; at 100 W you must mount it firmly to a metal chassis or heatsink with thermal compound to keep the element within safe temperature.
