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.
