Wire Wound Resistors Requiring High Power And Precision

Certain applications in electrical or electronic design call for a combination of:

  1. High power rating
  2. Tight tolerance on the resistance winding
  3. Wire wound construction

Obtaining all three of these requirements in a resistor calls for a unique type of resistor construction. The ASW series precision wire wound resistors have been used extensively for applications in industries ranging from power conversion, U.P.S. manufacture, lighting control, motor drive circuits (both a.c. and d.c.) and transportation.

With power ratings available in 1.5 watts, 3 watts, 6.5 watts, 8 watts and 11 watts these power resistors have an available tolerance as low as one percent depending on the required resistance value. The electrical stability is excellent and the resistors display a very low temperature coefficient. Some applications required a non inductive option, This is available in the ASW series via a winding of the resistance wire that is wound back on itself virtually eliminating the inductance of the resistance wire.
