METAL OXIDE RESISTORS, 1/2W to 9W RSF SERIES- Standard RMF SERIES- Miniature Low cost! Delivery from stock (standard E-24 values, 5%) Flameproof construction (UL94V-0) 0.1Ω to 1 Meg, standard tolerances: ±1%, ±2%, ±5% All sizes avail. on horizontal tape, ½-3W avail. on vertical tape Options include increased voltages, custom marking, cut & formed leads, Sn-Pb solder leads (Opt. Q), high pulse (Opt. P), etc. L H* d D RoHS Term.W is RoHS compliant & 260°C compatible RESISTORSCAPACITORSCOILSDELAY LINES RCD‘s oxide film resistors are ideally suited for medium-power applications. Surge levels exceed that of other film constructions. A thick complex-oxide material is deposited on a ceramic core for optimum heat dissipation, low inductance, and high stability even after extended periods. Series RMF (mini version) utilizes highest grade cores and special processing for increased power density. Flameproof coating offers excellent environmental protection and is resistant to solvents and humidity.
