Aluminium Chassis-Mount Wirewound Resistors

These 25W 12k ohm resistors use an aluminium housing for heat dissipation and mount directly to a chassis with screws. The wirewound construction handles high power loads and resists vibration in demanding environments. Supplied as a matched pair for balanced circuits.

12k Ohm ±5% Tolerance Value

The single specification that decides fit is the 12k ohm resistance with a ±5% tolerance band. Verify the schematic calls for this exact value and tolerance before ordering. A different resistance or tighter tolerance will change circuit behaviour.

25W Rating with Aluminium Heat Path

At 25W the part comfortably handles continuous power when bolted to a metal plate that acts as a heatsink. Without a solid thermal path the resistor will overheat well below the rated load. The 27mm body fits tight spaces but offers limited surface area for free-air cooling.

Questions about this item

Does 25 W mean the part can run that hot continuously inside a case?

The 25 W rating assumes the aluminium housing is bolted to a metal plate or chassis that can draw the heat away; without that thermal path the resistor will overheat well below the rated power.

What does the chassis-mount design with a 3.5 mm hole mean for wiring?

The resistor body is 27 mm wide and 53 mm long overall; the single 3.5 mm mounting hole lets you secure it to a panel or heatsink with a standard M3 screw while the two leads are soldered or crimped directly to the circuit.

Will the 27 x 16 x 15.5 mm body fit on a crowded board?

The ceramic-and-alloy body measures 27 mm long, 16 mm wide and 15.5 mm high, and the total length including terminals is 53 mm; allow at least that much clearance plus space for the mounting screw head.
