| Type THV Precision High Voltage Divider Networks Ratio TC to 10 ppm/C, Ratio Tolerance to 0.25%, Voltage Ratings of 10 KV, 15 KV or 20 KVDC 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(R) 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 from -55C to +125C. * Ratio Tolerances of 0.25%, 0.5%, 1.0% or 2.0% at Rated Voltage. * Voltage Ratings of 10 KVDC, 15 KVDC or 20 KVDC at +125C. * 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.
