About this product
A 3.9 Ω wire-wound resistor rated 25 W, housed in an aluminium case designed for chassis mounting. The metal housing provides heat sink capability, so it can be fixed to a cooling plate to dissipate heat in high-power circuits. Its ±5% tolerance and wire-wound construction suit power loads, dummy loads and current-limiting applications.

Can I mount it directly on a heatsink?
Yes. The aluminium housing is designed for chassis mounting and heat dissipation, so it can be fixed to a cooling plate or heatsink. Use a thermal compound for better heat transfer and tighten the mounting screws evenly.
How do I check the power margin?
Use P = V²/R or P = I²×R to confirm the dissipated power stays below the 25 W rating. Ratings are normally specified with good mounting and cooling, so derate the power when mounting is poor.
