Aluminum Housed Power Resistors

	A resistor encased in an aluminium housing normally having a flat base for mounting. Aluminium encased resistors are wound with Copper Nickel or Nickel Chromium wire, on a ceramic core fitted with end caps, to obtain required resistance. The winded assembly is then encapsulated in a anodized heat sink using high temperature moulding compound.
	Our high power wire wound resistors exhibit high performance life and are extensively used across industry. These resistors comply to international quality & safety standards.
	A wide range of Resistance available in 5w to 300 w.
	Small dimension & excellent heat transfer.
	Good Electrical Stability, Reliability & Mechanically strength.
	Values from E01 to 100 k.
	Non inductive version available.
	Customized termination, mounting arrangements available on request.
	Higher wattage resistors for special applications can be made.
