Caddock THV15 Series

  • Caddock

Product Features

  • Precision through-hole high voltage divider network
  • Total resistance of 150MΩ
  • Ratios of 100:1 or 1,000:1
  • Tighter ratio TCR and ratio tolerances than with standard high voltage divider products
  • Utilises Caddock’s Tetrinox® resistance films


The THV15 series from Caddock are precision high voltage divider networks, have a voltage rating of 15KVDC, with a total resistance of 150MΩ across the 2 resistors and a voltage division ratio of 1,000:1 or 100:1. They have a tighter ratio TCR and ratio tolerances than with standard high voltage divider product, The THV15 series introduces 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 laser generated V-Notch Geometry which optimizes the voltage gradient over the length of the resistance pattern.

  • Precision through-hole high voltage divider network
  • Resistance values available R1 = 149.85MΩ or 148.5MΩ to R2 = 150kΩ or 1.5MΩ with a total resistance of 150MΩ
  • Absolute TCR of ±30 ppm/°C (between -55°C and +125°C) and ratio TCR of ±25 ppm/°C or ±10 ppm/°C (between -55°C and +125°C)
  • Absolute tolerance of ±1.0% and ratio tolerance of ±0.25%, ±0.5% and ±1.0%
  • Maximum voltage rating of 15kVDC
  • Standard voltage division ratios of 1,000:1 or 100:1, with custom ratios available
  • Utilises Caddock’s Tetrinox® resistance technology
