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.
