The Type THV Precision High Voltage Divider Networks

introduce Caddock's advanced high voltage resistor tech-

nology which doubles the allowable working voltage over the

length of the high voltage section. This technology combines

Caddock's Tetrinox® resistance films with a patented laser-

generated V-Notch Geometry which optimizes the voltage

gradient over the length of the resistance pattern.

Type THV networks provide tighter ratio temperature

coefficients and tighter ratio tolerances than have previously

been available in standard high voltage divider products.

custom ratios available.

These specifications can provide important improvements

in performance in many types of advanced electronic systems,

including, TWT power supplies, radar systems, X-ray systems,

analytical equipment, and high resolution CRT displays.

Precision High Voltage Dividers: For assistance in specifying precision high voltage dividers

for your application please contact Caddock Applications engineering. We can offer high

voltage divider solutions based on the combination of catalog high voltage resistors, or by using

our well established capability to provide more precision in a Matched Resistor Set. Depending

on the performance you require, a precision high voltage divider solution can be formed using

Caddock Type USG and USF resistors, or Caddock Type TG and TK resistors, or a combination

of Type MG resistors.
