Two 25W 33k Ohm wirewound resistors

This pack contains two chassis-mount wirewound resistors rated at 33k Ohm with a 5% tolerance and a 25W power rating. They are built for circuits that need stable, high-power resistive loads such as power supplies, transducers or industrial audio equipment. The aluminium housing aids heat transfer to a mounting surface.

Check voltage and mounting clearance

Verify that your circuit never exceeds the 25W dissipation limit and that the 33k Ohm value matches the design specification. The body measures 27 x 16 x 15.5mm and the total length with mounting tabs is 53mm; ensure the enclosure has space for these dimensions. A 3.5mm mounting hole is required for the single screw fixing.

Aluminium housing enables cooling-plate use

The green anodised aluminium casing conducts heat to a chassis or cooling plate, allowing sustained 25W operation in harsh environments. Two resistors are supplied so you can populate dual-channel or redundant designs without sourcing a second pack. The wirewound construction provides good vibration resistance for elevator or arena installations.

Questions about this item

What comes in the package and do I need any extra hardware to mount these resistors?

The box contains two aluminium-housed 33 kΩ 25 W wirewound resistors. Each unit has a 3.5 mm mounting hole for screw fixing; screws are not included.

Should I pick the 33 kΩ 25 W version or is there another value I might need?

This listing only offers the 33 kΩ ±5 % 25 W model. Choose it when your circuit calls for that exact resistance and power rating; other values would require a different product.

Will the 25 W rating hold up when the resistor is bolted to a metal chassis inside a doorbell transformer?

Yes. The aluminium housing is designed for chassis mounting and heat-sink contact, so the 25 W rating is achieved when the body is firmly screwed to a metal plate that can draw away heat.
