Unique-Bargains 25W 8 Ohm Aluminium Housing Chassis Mount Wirewound Power Resistors Green 5pcs
Pack of five 8 Ω, 25 W wirewound resistors in aluminium chassis-mount housings for heat dissipation
- 25 W power rating handles demanding circuits
- 8 Ω ±5 % tolerance for precise resistance
- Aluminium chassis-mount housing dissipates heat efficiently
- Compact 27 × 16 × 15.5 mm body fits tight spaces
- Pack of five resistors ready for multi-point installs
Aluminium-housed wirewound resistors
These 25 W, 8 Ω wirewound resistors come in a green aluminium housing rated for chassis mounting. The pack contains five new components with a ±5 % tolerance, intended for power-supply, transducer, elevator and professional-audio circuits that demand stable high-power dissipation.
Chassis-mount design with screw holes
Each unit measures 53 mm overall length and 27 mm body length, with a 3.5 mm mounting hole for direct screw fixing to a metal panel or cooling plate. The aluminium case transfers heat away from the ceramic-alloy core, freeing the builder from adding separate heatsinks in space-constrained enclosures.
Sustained 25 W dissipation
Rated for continuous 25 W operation, the resistor maintains its resistance value under prolonged load without the drift seen in short-pulse tests. The wirewound construction and high insulating capacity resist vibration-induced noise, making the parts suitable for equipment that runs continuously in harsh environments.

Questions about this item
At what power level does the 8 ohm resistor reach its thermal limit under sustained load?
The resistor is rated for 25 W continuous dissipation; exceeding that rating will cause the aluminium housing to exceed its safe temperature.
How hot does the aluminium chassis get when the resistor runs at full power all day?
At 25 W the housing becomes very hot — designed for mounting on a cooling plate to transfer heat away from the 27 x 16 x 15.5 mm body.
What mounting hardware must I already have to install these chassis-mount resistors?
You need a flat metal surface with two 3.5 mm clearance holes spaced for the 53 mm total length, plus screws to clamp each 69 g unit securely.
