Datasheet

The MG precision high-voltage axial standard resistor range from Caddock offers a resistance range from 200Ω up to 2GΩ 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 from ±1% down to ±0.1% 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.
