Rod & Tube Resistors

Rod & Tube Resistors

HVR Rod and Tube Resistors are manufactured from a carefully selected mixture of clays, alumina and carbon. After blending, the material is extruded into the required shape and then fired, in a controlled atmosphere, at high temperature.

Aluminium is then flame sprayed onto the barrel surfaces (as standard) to provide electrical contact. Alternative metallised contacts and corona shielded terminals are also available.

With High Surge Energy Rating and Low Inductance, typical applications for HVR Rod and Tube Resistors include Dummy Aerial Loads, Overvoltage Protection, Capacitor Discharge and Anti Parasitic Elements in the grid and anode circuits of power valves in induction heaters.
