Product Description

 Aluminium High Frequency Resistors are wound with Nickel Copper or Nickel Chromium wire for obtaining required resistance on a ceramic core fitted with end caps. The winded assembly is then encapsulated in a anodised Heat sink using high temperature moulding compound.


Features of Aluminium High Frequency Resistors 

  • Low Cost, Light weight &Compact.
  • Non-inductive Type available.
  • Custom Values available.


Application

These Resistors are applied where high wattage dissipation is required in a small space. The metal heat sink ensures good heat dispersal & allows a low hot-spot temperature. Major application include Induction furnace, Medical equipments, Humidity Chambers etc.
