Unique-Bargains Aluminum Case Resistor 100W 0.25Ohm Wirewound Gold

High-Power Wirewound Resistor

This Unique-Bargains aluminum-cased wirewound resistor is rated at 100 W with a 0.25 Ω resistance and 5 % tolerance. The compact body measures 59 mm or 2.32 in long and uses copper, nickel and aluminium construction for reliable heat dissipation. Two 2 mm soldering rods and a 3.2 mm mounting hole suited to #2 or M2.3 hardware allow secure board attachment.

Engineers needing steady load handling

Designers replacing LED flush-mount drivers, building AC/DC converters, inverter stages or motor-speed controls will find the stable wirewound element a direct fit. Projects that demand surface-mount packaging, higher resistance values or lower power ratings should consider alternative component types instead.

Continuous dissipation via aluminium housing

The extruded aluminium case acts as the primary heatsink, so sustained 100 W operation relies on unrestricted airflow around the 59 mm body. Without adequate convection or forced air the element will reach thermal limits faster than the rated continuous power suggests, so mechanical mounting to a chassis or additional heatsinking becomes necessary for prolonged heavy-duty cycles.
