  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.

•

 Ratio Temperature Coefficients of 10 ppm/°C or 25 ppm/°C  

  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  

  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.
