Product Overview
TEPRO TM 5 watt, 2 Ohm 0.1% Black Aluminum Chassis-Mount Resistor
This black-painted aluminum power resistor provides a stable low ohm/Ω value for sensing, load, and damping roles in compact assemblies. The coated housing bolts to a panel or heatsink for dependable thermal transfer, and a practical installation tip is to ensure full surface contact beneath the finish. This helps maintain consistent performance under power.

Product Overview
The TEPRO TM series is a wirewound, chassis-mount family built for precise low-value resistance with rugged mounting options. This 2 Ω, 0.1% version features a black-painted aluminum housing that aids abrasion resistance while supporting efficient heat conduction when secured to a metal surface. The internal ceramic core and wirewound element contribute to stable operation across a range of temperatures, and the lug/tab terminals provide straightforward wiring in industrial or test setups.

Frequently Asked Questions
What is the purpose of the black painted finish?
The painted aluminum housing adds surface durability while retaining the thermal characteristics expected of a bolt-down power resistor.
Does the resistor still require mounting to a chassis?
Yes, full power handling depends on firm mounting to a metal panel or heatsink for thermal conduction.
Is this resistor suitable for precise sensing applications?
The 1% tolerance and stable wirewound construction support accurate low-value measurements.
Can it operate in varied environments?
The TM series supports use in air, oil, vacuum, or inert atmospheres, suitable for industrial and lab settings.
You can bolt the black aluminum housing to a metal panel for effective heat transfer and use its controlled 2 Ω value to build reliable current-sense or damping stages in compact power assemblies.
