Type MM and ML Precision Film Resistors
High Temperature Resistors for Geophysical, Industrial, and Military Requirements
Type MM and ML resistors have a proven performance history in industrial and military applications. Utilizing
our proven Micronox ® resistance films, these resistors are available with power ratings up to 1 Watt
and resistance values to 10 Megohms. These resistors are ideal for applications requiring tolerances as close as 0.1% and
extended life stability of 0.1% per 1,000 hours.
Some models of Type MM and ML resistors are manufactured with Caddock's Non-Inductive Design that provides for
neighboring lines to carry current in opposite directions. This efficient non-inductive construction is accomplished without
derating of any performance advantages.
Type MM features:
• Max. Operating Temperature to +275°C.
• High Power Rating at +125°C.
• TC of 50 ppm/°C from -15°C to +105°C.
• Non-Inductive Performance Available.
