PRECISION METAL FILM RESISTORS FEATURES EIA RS-460 available DERATING Wide resistance range: 1.02 to 22.1 Meg TC +25 to + 100 PPM standard. Matching to 10 PPM Tolerances +.1% to + 1%. Matching to .02% Precision quality, excellent stability, reasonable cost Exceeds performance requirements of MIL-R-10509 & Extremely low noise, reactance, voltage coefficient Exclusive RCD SWIFT delivery available! Hi-Rel performance and Group A screening per MIL-R-55182 Flameproof and/or fusing characteristics available All sizes available on Tape-and-Reel RCD MF resistors have an operating temperature range of 65C to + 175C and must be derated as follows: 120 100 80 60 40 20 0 % OF RATED POWER 30 MIL-Grade Performance Levels! RCD MF Series Metal Film Resistors have been designed not only to meet but also surpass the performance specifications of MIL- R-10509F characteristics D, C, E. The film is a proprietary thin film nickel-chrome alloy, evaporated onto a high grade substrate using a high vacuum deposition process to insure low temperature coefficients and superb stability with time and temperature. The resistors are coated or encapsulated with an exclusive high-temperature epoxy to insure maximum seal integrity, solvent resistance, and mechanical strength. Special methods coupled with stringent controls are used in every step of production to ensure built-in reliability and consistent quality. Resistors are available with alpha-numeric or color band marking. ir = po ne L + .032 [.80] D + .025 [.64] d (MAX) H (MIN) MF50 150[ 3.8] | .065:[1.7] 018 [.4] 94 [24] MF55 .280[ 7.1] | .105 [2.7] .025 [.6] 1.00 [25] MF60 .380[ 9.6] | .140 [3.5] 025 [.6] 1.10 [28] MF65 575 [14.6] | .180 [4.6] 025[.6} | 1.125 [28.6] MF70 610 +.062 | 180 [4.6] 032[.8] | 1.125 [28.6] 50 70 90 110 130 150 170 190 AMBIENT TEMP.
