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.
Industry’s widest resistance range: 1.0Ω to 22.1 Meg
TC ±25 to ±100ppm standard, available to 10ppm
Precision quality, excellent stability, low cost
Meets general performance requirements of
MIL-R-10509 and EIA RS-460
Extremely low noise, reactance, voltage coefficient
Numerous values available from stock in each type
Available on exclusive SWIFT TM delivery program!
All sizes available on Tape & Reel
