Military-grade performance at commercial grade price!

RCD MF Series metal film resistors have been designed to meet or

surpass the performance levels of MIL-R-10509 characteristics D,

C, and E. The film is a nickel-chrome alloy, evaporated onto a high

grade substrate using a high vacuum process to ensure low TC’s

and superb stability. The resistors are coated or encased with a

high-temp epoxy to ensure utmost moisture and solvent protection.

Stringent controls are used in each step of production to ensure

‘built-in’ reliability and consistent quality. Resistors are available

with alpha-numeric or color band marking.

OPTIONS

Custom marking, formed leads, matched sets, burn-in, in-

creased power/voltage/pulse capability, flameproof, etc.

Mil-spec Group A or A&B screening available
