16 February 2015. Continuing on with out wire wound resistor selection series, this week we take the example of a high power resistor – namely a 500 watt power resistor. In this example our application calls for a 500 watt rated resistor that has a 5 percent tolerance and 470 ohm adjustable resistance.

A 500 watt rated resistor, by its very power rating, calls for a rugged, highly reliable method of construction, with the ability to dissipate significant amounts of heat from the body of the resistor. From our wire wound resistor product selection guide, we can see that the Y Series […]
