The MG precision high voltage axial resistor series from Caddock offers a voltage rating of up to 30kV (standard series) or 48kV (-15 variant), power rating of up 15W and a resistance range from 200Ω up to 2GΩ (standard series) or 10GΩ (extended range), all in a cylindrical axial leaded through-hole package. Caddock's Micronox® resistance films are the source of their outstanding combination of performance features. The MG series offers tolerances from ±1.0% down to ±0.1% across the standard series or ±1.0% for both -15 and extended ranges.
The exceptional performance of the Caddock MG series has been proven through many years of use in equipment that demands the highest reliability and stability, including TWT amplifiers, X-ray systems, geophysical instruments and medical electronics.
Most models of the MG series are manufactured with Caddock's non-inductive design which uses a serpentine resistive pattern that provides for neighbouring lines to carry current in opposite directions, thereby achieving maximum cancellation of flux fields over the entire length of the resistor. The efficient non-inductive construction is accomplished without derating of any performance advantages.
Additional options to the standard resistor range includes extended resistance values and the -15 option for increased maximum operating voltages.
