ConstructionAluminium housed Resistor 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 Low Cost, Light weight & Compact. Non-inductive Type available. Custom Values available. ApplicationThese 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.   Deratings Deratings required for reduced chassis Mounted area and for high ambient temperatures. Derate to zero Power Linearly at 250oC ambient. Derating necessary for unmounted resistors at ambient
