Chassis-mounted 50 W audio resistor

The Unique-Bargains unit is a gold-tone aluminium-clad power resistor rated at 50 W with an 8 Ω nominal value and ±5 % tolerance. It is intended for live-sound amplifier builders and repair technicians who need a chassis-mountable load or damping component.

Heat dissipation through direct chassis contact

The aluminium case includes screw tabs that fasten the body directly to a chassis or heatsink, allowing sustained power handling by conducting heat away from the resistive element. Stable performance is maintained at high operating temperatures and high ultimate voltage thanks to the extensive resistance track and compact 7.3 × 2.2 × 1.5 cm outline.

Verify mounting geometry and electrical fit

Confirm that the 1.8 mm mounting-hole diameter and 2.9 × 0.9 × 0.6 inch overall footprint match your chassis layout before ordering. Ensure the 8 Ω value and 50 W rating suit the amplifier stage you are designing or servicing, as no alternative impedances or power levels are offered in this listing.

Questions about this item

How much heat can the 50W aluminum-clad resistor dissipate when mounted to a chassis?

The 50W power rating is achieved when the aluminum case is screwed tightly to a chassis or heatsink, using the mounting tabs to transfer heat away from the resistive element.

What mounting hardware is required to install the 1.8mm diameter mounting holes?

You need screws or bolts that fit a 1.8mm / 0.07" diameter hole, plus a flat metal surface such as a chassis panel or heatsink to clamp the resistor against for thermal transfer.

Will the 7.3cm length fit alongside older crossover components in a vintage speaker cabinet?

At 7.3cm long, 2.2cm wide and 1.5cm high, the resistor is compact enough to sit beside legacy crossover parts, provided the cabinet has a flat area for the mounting tabs.
