TEH140
TEH140 is 140 Watt TO-247 Power Resistors manufactured by OHMITE.
TEH140 Series
140 Watt TO-247 Power Resistors for High Frequency and Pulse Loading Applications
F e a t u r es
- 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
- plete 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
