Type THV Precision High Voltage Divider Networks0 pages
Type THV Precision High Voltage Divider Networks
Ratio TC to 10 ppm/°C, Ratio Tolerance to ±0.25%, Voltage Ratings of 10 KV or 15 KV
The Type THV Precision High Voltage Divider Networks
introduce Caddock's advanced high voltage resistor technology 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 lasergenerated 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.
• Ratio Temperature Coefficients of 10 ppm/°C or 25 ppm/°C t
from -55°C to +125°C.
• Ratio Tolerances of ±0.25%, ±0.5%, or ±1.0% at
Rated Voltage.
• Voltage Ratings of 10 KVDC or 15 KVDC
• Standard Voltage Division Ratios of 1,000:1 or 100:1, with t
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.

evaluation and production quantities, contact Caddock

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.
