Unique-Bargains Aluminum Case Resistor 100W 0.33Ohm 2Pcs

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.
