Thick Film Power
Due to their non-inductive design, these resistors are
ideally suited for high-frequency and pulse-load applications. Available in 120- or 200-watt sizes, this resistor
is designed for direct mounting onto a heatsink. Popular
applications include variable speed drives, power supplies, control devices, telecom, robotics, motor controls,
and other switching designs.

THIS PRODUCT IS DESIGNED FOR
USE WITH PROPER HEATSINKING.
Maximum base plate temperature of the resistor must
be monitored and kept within specified limits to establish the power rating. Best technique is to attach a
thermocouple to the side of the base plate of the resistor. Temperature of plastic housing or heat sink cannot
be used to establish rating of the resistor.
