Type MM and ML Precision Film Resistors High Temperature Resistors for Geophysical, Aerospace and Industrial Requirements Type MM and ML resistors have a proven performance history in industrial, computer, military and space applications. Utilizing our proven Micronox resistance films, these resistors are available with power ratings up to 3 watts and resistance values to 15 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. Most 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: Non-Inductive performance at a low cost. TC of 50 ppm/C from -15C to +105C.
