Vishay: New EDGU Universal Edgewound Power Resistor

Vishay Intertechnology, Inc. introduces a new universal edgewound power resistor. Providing a convenient drop-in replacement for competing solutions, the universal-mounted EDGU combines a high-reliability design with continuous duty operation up to 85 A and a short-time overload of 10x rated power for five seconds.

  • Features a resistance-alloy ribbon wire that is coiled on edge and supported on specially designed porcelain insulators
  • Open coil construction allows for efficient heat dissipation and easily accommodates overloads and surges
  • Insulators provide proper turn-to-turn spacing and insulation from support bars
  • Terminals are welded to the resistive wire for a reliable electric connection
  • Wirewound
  • Can be mounted on Vishay Milwaukee frames or in NEMA 1, 2, or 3R enclosures

Product Benefits:

  • Current ratings up to 85 A
  • Power ratings to 1600 W
  • Short-time overload of 10x rated power for five seconds
  • Wide resistance range from 0.053 Ω to 5.44 Ω, with tolerance of ± 10 %
  • High-reliability design
  • Customizable
  • RoHS compliant

Market Applications:

  • Pre-charge, discharge, dynamic braking, load testing, and heater applications in locomotives, wind turbines, and harmonic filters


  • Samples and production quantities of the EDGU are available now, with lead times of four weeks for larger orders.
