100W 2 Ohm Wire Wound Resistor

This aluminium-housed wire wound resistor delivers 100 W of power dissipation at a 2 ohm resistance with a 5 % tolerance. The green anodised casing is designed for mounting on a cooling plate, making it suitable for industrial power supplies, transducers, elevator controls and high-demand audio equipment. Buyers who need a different resistance value or a lower power rating will not find those options in this listing.

Screw tap terminals and aluminium housing

The resistor body measures 59 x 15 mm with an overall size of 81 x 21 x 15 mm, providing two mounting holes of 1.8 mm and 3 mm diameter for secure fixing. Screw tap connections allow multiple wiring modes and quick installation without soldering. The aluminium shell gives high insulation and good vibration resistance, while the non-inductive winding option supports clean signal handling.

100 W continuous load headroom

At 100 W the component handles sustained high-power loads in harsh environments, provided adequate thermal transfer to a cooling plate is maintained. The 30 g weight and compact footprint leave little margin for overloads beyond the rated dissipation, so designs requiring higher continuous power or forced-air cooling without a mounting surface will need a different solution.

Questions about this item

Does the aluminum housing need any maintenance or replacement over time?

The aluminum housing is built for heat dissipation and harsh environments; no routine maintenance or replacement is expected under normal use.

What limit appears first when the resistor runs at 100W continuously?

The 100W power rating is the primary limit; sustained operation at full load will push the body temperature to its design maximum.

How much noise, heat or power draw occurs when it runs all day?

Wire-wound construction is silent; the 59 x 15mm aluminum body dissipates heat for 100W continuous load, and the component only draws the circuit's required power.
