25 W 12 Ω chassis-mount wirewound resistor

This aluminium-housed wirewound resistor provides a precise 12 Ω value with ±5 % tolerance and a 25 W power rating. It is built for engineers and technicians who need reliable power dissipation in industrial equipment, power supplies, transducers or audio systems.

Aluminium housing with mounting hole

The gold-tone aluminium case measures 28 × 16 × 15.5 mm body size and 53 × 28 × 15.5 mm overall, with a 3.5 mm mounting hole for screw fixation. This construction enables direct attachment to a cooling plate, improving thermal transfer and vibration resistance in harsh environments.

25 W continuous power rating

The single figure that determines suitability is the 25 W power rating; circuits demanding higher continuous dissipation must choose a different component. Buyers needing lower power or surface-mount packaging will not be served by this through-hole part.

Questions about this item

Will the aluminium housing need re-torquing or thermal-paste renewal after long service?

The aluminium housing is a single-piece chassis mount with a 3.5 mm fixing hole; no moving joints or thermal-interface pads are specified, so no scheduled re-torquing or paste renewal is required.

At continuous 25 W dissipation, which limit appears first — resistance drift or case temperature?

The 25 W rating is the design ceiling; sustained operation at that level will reach the maximum allowed case temperature before the ±5 % tolerance band is exceeded.

How hot and noisy does the gold-coloured resistor get when mounted on a plate and run all day?

The aluminium case acts as the heatsink; it runs warm but silent, with no fan or moving parts, and is described as suitable for cooling-plate installation in harsh environments.
