Unique-Bargains Aluminum Case Resistor 10W 120 Ohm Wirewound Rod Post

10W 120 Ohm Wirewound Resistor

This aluminum-housed wirewound resistor handles 10 watts at 120 ohms with a 5% tolerance. It is suited for LED converter circuits, speed-control boards and other power-dissipation tasks where a compact chassis-mount part is required.

Rod-Terminal Mounting

Two rod terminals with 2.5 mm screw holes are spaced 14 mm centre-to-centre and accept #2 or M2.3 hardware. The 1.9 cm body leaves a small footprint, but the rods are only 7.7 mm long so verify that your board or bracket thickness allows full thread engagement before committing to a layout.

Steady-State Thermal Behaviour

The aluminum case acts as the heatsink; sustained 10 W operation demands secure mechanical contact to a metal panel or chassis to keep the element within safe temperature limits. Without that thermal path the resistor will exceed its rating during continuous load, unlike brief pulses where the case mass absorbs the energy.
