Aluminium-housed 560 Ω 25 W wirewound pair

Two chassis-mount resistors rated at 560 Ω with ±5 % tolerance and a 25 W power rating. The aluminium housing provides heat dissipation and allows mounting on a cooling plate. Wirewound construction delivers stable performance in high-vibration environments. Supplied as a pack of two for replacement or prototype work.

Suits engineers fitting ring doorbells

Ideal for builders who need a compact, high-power resistor that can be bolted to a chassis or cooling plate. The 27 mm × 16 mm × 15.5 mm body fits tight spaces while handling 25 W. Not for buyers who require a different resistance value, tighter tolerance or a surface-mount package. Those needing inductive or non-inductive specification beyond the standard wirewound type should look elsewhere.

560 Ω at 25 W in aluminium chassis mount

The single deciding specification is the 560 Ω, 25 W rating in a screw-fix aluminium case. If your circuit calls for exactly that resistance and power level with through-hole mounting tabs, these two resistors match the requirement. Any other resistance, power rating or mounting style means this pack is not the correct part.

Questions about this item

How do I mount the aluminium housing resistor to a cooling plate and what hole size should I drill?

Drill a 3.5 mm clearance hole for the mounting screw; the housing measures 53 mm long, 27 mm wide and 15.5 mm high, so align the screw with the chassis tab before tightening.

Will the ceramic wirewound element need periodic replacement or can it run continuously at 25 W?

The wirewound element is rated for continuous 25 W dissipation; with proper heat-sinking to the aluminium case it has no scheduled replacement interval.

At what point does the 560 Ω resistance drift beyond the ±5 % tolerance during sustained 25 W operation?

The datasheet specifies ±5 % tolerance at rated power; sustained 25 W loading with adequate cooling keeps resistance within that band.
