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.

Questions about this item

What board length and mounting holes does the 100W 0.25 ohm resistor need for installation?

The main body measures 59 mm or 2.32 inches and has two rods with 2 mm holes for soldering plus a 3.2 mm antisymmetric anchoring hole that fits #2 screws or M2.3 nuts.

Can the aluminum-housed wirewound resistor replace a flush LED in an existing AC DC circuit?

Yes, the supplier notes it solves flush-LED problems and works in AC DC circuits, converters, inverters, motor speed controls and drivers.

How can I verify the 100W 0.25 ohm resistor is operating correctly after wiring it?

Measure the resistance across the terminals — it should read 0.25 ohm within the 5 % tolerance — and confirm the aluminum case stays within safe temperature limits under load.
