FM Fusible Flameproof Resistors FM Series: Axial Leaded, Film FEATURESINTRODUCTION FUSING CHARACTERISTICS DERATING CURVE 70 C 155 C o o Co High stability, accuracy, and reliability Noncombustible coating Uniform fusing time Low temperature coefficient (350ppm/ ) For wire wound version, see FKN Co The fusible resistor contains two functions in one package. It’s a resistor under normal conditions and a fuse (with a predictible fusing time) when subjected to higher than normal current. 01-MAR-2023 Page 1 of 2 RFE International • Tel (949) 833-1988 • Fax (949) 833-1788 • E-mail sales@rfeinc.com Standard tolerance is 5% and 10% for values below 0.5 Ω. • SPECIFICATIONS L ± 1.0 D ± 0.5 C ± 3 d ± 0.05 1/4W FM25 6.5 2.3 30 0.55 0.1~10K 200 250 5 1/2W FM50M 6.5 2.3 30 0.55 0.1~10K 200 250 5 1/2W FM50 9 3.2 30 0.65 0.1~10K 250 250 5 1W FM100M 9 3.2 30 0.65 0.1~10K 250 250 5 1W FM100 11.5 4.5 30 0.78 0.1~10K 300 350 5 2W FM200M 11.5 4.5 30 0.78 0.1~10K 250 350 5 2W FM200 15.5 5.0 30 0.78 0.1~10K 350 400 5 3W FM300M 15.5 5.0 30 0.78 0.1~10K 250 400 5 Std.
