INTrOdUCTION
The HVR Series High Voltage Resistors are manufac-
tured using vacuum sputtering system to deposit
multiple layers of mixed metals alloy and passivative
materials onto a carefully treated high grade ceramic
substrate. After a helical groove has been cut in the
resistive layer, tinned connecting leads of electrolytic
copper are welded to the end-caps. The resistors
are coated with layers of gray color lacquer.
deraTING CUrVe
For resistors operated in ambient temperatures above 70°C, power rating must be derated in
accordance with the curve below.
