| 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 (R) 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 +275C. * High Power Rating at +125C. * TC of 50 ppm/C from -15C to +105C. * Non-Inductive Performance Available. Type ML features: * TC of 50 ppm/C from -15C to +105C. * Non-Inductive Performance Available.
