Precision High Voltage Resistors

The MG precision high-voltage axial resistor range with extended values from Caddock offers a resistance range from 600Ω up to 10GΩ and a voltage rating up to 30kV with the possibility of 1.5 times maximum continuous operating voltage for 5 seconds. The power rating for these resistors is up to 15W with the possibility of 5 times rated power for 5 seconds (not exceeding maximum voltage). The MG series offers tolerances of ±1% and ±5% and has demonstrated stability of 0.01% per 1,000 hours in extended load life testing. Caddock’s Micronox^® resistance films are the source of their outstanding combination of performance features.
