TT Electronics' WMHP series radiator-mounted high-power resistors use non-inductive thick film technology to ensure low thermal resistance, making them suitable for high frequency and fast pulse use. They are available in TO-220 and TO-147 standard power packages and are rated from 20W to 100W.
These parts have high surge and frequency performance. Thick film technology across the entire ohm range provides stable reliability under surge conditions, reducing the cost of field failures. Powerful surge and high frequency performance make it ideal for fast switching power supply circuits in motor drive or power applications.
Their resistance ranges from 50mohm to 10kohm, which is suitable for low value current detection and general power resistor applications. The company says these products offer 1% and 50ppm / C accuracy and operating temperatures up to 175C.
