PRECISION METAL FILM RESISTORS MF SERIES RoHS RESISTORSCAPACITORSCOILSDELAY LINES Term.W is RoHS compliant & 260C compatible Wide resistance range: 1.0 to 22.1 Meg TC 25 to 100ppm standard, matching to 10ppm Precision quality, excellent stability, low cost Meets performance requirements of MIL-R-10509 and EIA RS-460 (screening per Mil-PRF-55182 available) Extremely low noise, reactance, voltage coefficient Available on exclusive SWIFT TM delivery program! All sizes available on Tape & Reel 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.
