TKH45 product image

 

Features

  • Small size, low profile, surge capable film resistor
  • 55°C to +175°C temperature range provides for automotive applications.
  • Low thermal resistance under 3.0°C/W shows excellent cooling performance.
  • Easy to replace D-PAK power resistor.
  • Excellent rf characteristics for high speed pulse operation./li>
  • Applications include snubber, gate control, bleeder, filter, rush current protection, PV, UPS and motor control inverters.
