Caddock THV10 Series

The THV10 series from Caddock are precision high voltage divider networks, have a voltage rating of 10KVDC, with a total resistance of 100MΩ 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 THV10 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
