Precision Film Resistors

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:

Models with low inductance construction are in shaded areas

Models with Caddock’s non-inductance resistance pattern are in non-shaded areas

The continuous maximum applied voltage cannot exceed the maximum power rating and is ohmic value dependent.
Value range is case size dependent.
