Due to their non-induc-
tive 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 mount-
ing onto a heatsink. Popular
applications include variable
speed drives, power supplies,
control devices, telecom, robot-
ics, motor controls, and other
switching designs.
