Features and Applications
140W high power resistor in TO-247 molded package.
Only 0.9 °C/W heat resistance between resistor and flange for excellent cooling.
Wide 10mΩ to 510kΩ resistance range, non-inductive design fit for high frequency circuit and wide
band amplifiers.
Small size and thin shape provides for high density design of power electronics.
Complete thermal conduction and heat dissipation design will be available.
Applications include power electronics / inverter of automotive, rail traction, wind turbine, PV, UPS and
industrial motor control as harmonic filter, dumping, snubber, gate control, bleeder resistor and rush
current protection,
