AVT Adjustable Wirewound Resistors


Huntington Electric’s AVT resistors give designers the ability to adjust to specific resistance values


Huntington Electric’s AVT resistors give designers the ability to adjust to specific resistance values while still providing the larger power ratings that are common on fixed wirewound resistors. These adjustable resistors are constructed with steatite ceramic cores, terminated with welded terminals, and wound with the finest alloy resistance wires welded to the terminals.

The AVT series has a vitreous enamel coating used to insulate the resistors. A section of the windings are made bare for connecting to a band terminal that implements the adjustment function. This construction insures long life, durability, and reliability. Datasheet
AVT Adjustable Wirewound Resistors

Applications Features
  • Instances where a power resistor should be used but an odd resistance value is needed
  • Instances that require power resistors but also require occasional resistance adjustments (e.g. moving to a place with differing supply voltage)
  • Highly adjustable
  • Power ratings from 12~225W
  • Separate brackets allow for easy mounting
  • RoHS compliant
