THV10-A100M-1.0-25 fiche technique
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 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%, ±1.0% or ±2.0% at
Rated Voltage.
Voltage Ratings of 10 KVDC, 15 KVDC or 20 KVDC at +125°C.
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.
