Aluminum housed 10 W 20 Ω resistor

This wire-wound resistor comes in an aluminium case that acts as its own heat sink. Rated at ten watts and twenty ohms with a five-per-cent tolerance it suits LED converters, speed-control circuits and similar power-dissipation tasks. The gold-coloured body measures 1.9 cm long and weighs 6 g.

Rod terminals with 2.5 mm screw holes

Two rod posts each 7.7 mm long include 2.5 mm clearance holes spaced 14 mm centre-to-centre so they accept M2.3 or #2 hardware. The through-hole rods allow direct PCB mounting or chassis bolting without extra brackets. No additional connector or socket is required.

Passive aluminium-case cooling

The aluminium housing transfers heat directly to the surrounding air so the resistor runs within its ten-watt rating without forced airflow. Silent operation is inherent because there are no moving parts. Power draw is determined solely by the applied voltage across the twenty-ohm element.

Questions about this item

At what power level does the 10 W aluminum-housed resistor reach its thermal limit?

The resistor is rated for 10 W continuous dissipation; its aluminum case transfers heat away from the wire-wound element so the thermal limit is reached at the rated 10 W.

How hot does the case get and what noise does it make when run at 10 W all day?

The aluminum case becomes hot to the touch at full 10 W load but the resistor has no moving parts and therefore produces no audible noise.

What mounting hardware must I already have to secure the 2.5 mm screw holes spaced 14 mm apart?

You need #2 or M2.3 nuts and bolts to fasten the resistor through its 2.5 mm mounting holes set 14 mm center-to-center.
