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 Cad dock's Non-Inductive Design that provides for
neighboring lines to carry current in opposite
directions. This effi cient non-inductive construction is accomplished without
derating of any performance advantages.
