AVT
WIREWOUND RESISTORS
AST
H.E.I. Adjustable Resistors are constructed with
steatite ceramic cores and terminated with welded terminals and wound with
the finest alloy resistance wires welded to the terminals. Our special formula
of vitreous enamel (AVT) or silicone (AST) coatings are then used to insu-
late 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.
