Description
H.E.I. Axial Lead Resistors are constructed with steatite ceramic cores or alumina, terminated with welded cap and lead assemblies and wound with the finest alloy resistance wires welded to the cap and lead assemblies. Our special formula of vitreous enamel (ALVR) or silicone (ALSR) coatings are then used to insulate the resistors. This construction insures long life, durability, and reliability.
