Unique-Bargains 25W 7.5k Ohm Wirewound Resistor Aluminium Housing Green 1pcs
A 25 W wirewound resistor rated at 7.5 kΩ ±5 %, housed in a green aluminium chassis-mount case measuring 53 × 27 × 15.5 mm with a 3.5 mm mounting hole
- Featurescool plate Chassis Mount Aluminum Housing resistor;high powe
- 25 W power rating supports demanding circuits
- Aluminium housing draws heat away from the windings
- Chassis-mount design with 3.5 mm fixing hole secures the resistor
- Compact 27 × 16 × 15.5 mm body fits tight spaces
- ±5 % tolerance on 7.5 kΩ value ensures predictable performance
25 W 7.5 kΩ Chassis-Mount Resistor
This aluminium-housed wirewound resistor is rated for 25 W continuous dissipation at 7.5 kΩ with a ±5 % tolerance. It is built for engineers and technicians who need a single, rugged power resistor for industrial or repair work.
25 W Power Rating Decides Suitability
The 25 W rating is the figure that determines whether this part can handle your circuit's thermal load. If your design demands higher continuous power or a different resistance value, this component will not meet the requirement.
Simple Screw Mounting With One Fixed Hole
The resistor body measures 27 x 16 x 15.5 mm and the total length including tabs is 53 mm. A single 3.5 mm mounting hole allows direct chassis attachment; the main installation issue is ensuring the mating surface is flat so the aluminium housing can transfer heat effectively.

Questions about this item
What does the 25 W rating mean once the resistor is mounted in a real circuit?
The 25 W rating is the continuous power the resistor can dissipate when its aluminium housing is firmly bolted to a metal chassis or cooling plate that can carry the heat away; without that thermal path the safe dissipation drops sharply.
What mounting interface does the chassis-mount design use and what does it limit?
The resistor has a single 3.5 mm mounting hole for a screw; the mechanical fixing also serves as the main thermal interface, so the chassis material and flatness limit both vibration resistance and heat flow.
What physical space and hole pattern are needed to fit this resistor?
The body measures 27 x 16 x 15.5 mm and the overall length including tabs is 53 mm; a 3.5 mm clearance hole is required for the mounting screw.
