Product Overview
The Caddock Type HVD Ultra-Precision Voltage Dividers are monolithic voltage divider networks featuring a robust, ceramic-sandwich construction designed for high-voltage DC applications. They offer ultra-precision performance with continuous voltage ratings up to 5000 VDC. Ideal for demanding applications in Test & Measurement Instruments, Medical Equipment, Industrial Equipment, Materials Analysis, and Laboratory Equipment, these dividers provide precise DC voltage division with excellent transient tolerance. Custom performance options are available, including tailored R2 resistance values for custom voltage divider ratios between 100:1 and 1,000:1, or optimized cost with reduced voltage ratings, looser tolerances, and extended temperature ranges.
