The MM high temperature precision axial leaded resistor series from Caddock offers a resistance range from 30Ω up to 10MΩ, a power rating of up to 1W (MM215 model) and a voltage rating of up to 800V (MM215 model). The MM series has a tolerance of ±1.0% as standard, with options down to ±0.1% on special order, and also a TCR of ±50 ppm/°C (between -15°C and +105°C). These resistors are produced with Caddock’s proven Micronox® resistance films.

  • High temperature high voltage precision axial leaded resistor
  • Available in any resistance between 30Ω and 10MΩ
  • Utilises Caddock’s Micronox® resistance film technology
  • The MM215 model utilises Caddock’s non-inductive design
  • Tolerance of ±1.0% as standard with options down to ±0.1% on special order
  • TCR of ±50 ppm/°C (between -15°C and +105°C)
  • Maximum working voltage of up to 800V (model dependent)
  • Maximum power rating of up to 1W (model dependent)
  • Maximum operating temperature to +275°C


Some models of the MM series are manufactured with Caddock’s non-inductive design that provides for neighbouring lines to carry current in opposite directions. This efficient non-inductive construction is accomplished without derating of any performance advantages.

MM high temperature high voltage precision resistors have a proven performance history in industrial and military applications.


The below table gives the specifications available for the complete MM resistor series:
