Features and Applications
50W high power resistors in TO220 style mold package for and screw mount.
Non-inductive design suits high frequency applications and high-speed pulse circuits.
Low, 2.3 deg °C/W heat resistance from resistor hot spot to flange and long life performance are
presented with thin film metallization technology and rejection of plastic adhesive joint.
Wide 20 milli Ohm to 510kOhm resistance range, non-inductive impedance characteristic and heat
conduction through the insulated metal flange aids circuit designers.
Small size and thin profile suit high-density compact installations.
Complete thermal conduction, heat dissipation design and vibration durable design also available.
Applications include snubber, gate control, bleeder, filter, rush current protection, braking resistors of
automotive, rail traction, wind turbine, PV, UPS and motor control inverters.
