Precision performance, flameproof design per UL94V-0 Fusing-to-Operating current ratios as low as 3:1!Fusing times available from 1 millisecond to 30 seconds Available on exclusive SWIFT TM delivery programCustom design available for increased surge capability (specify Option P)Also available: Hi-Rel screening, burn-in, custom marking, etc.FAILSAFE FUSE RESISTORS 1/2 WATT to 50 WATTFR SERIESPrecision Grade Fuse Resistors!RCD’s FR Series was designed to obtain the best from two devices. It combines the performance of a precision grade resistor with precisely controlled fusing characteristics. Typical applications include protection for zener diodes and other semiconductor components, emitterresistors for current sharing transistors, Squib circuits, and/or other circuits that require precision fusing chracteristics unobtainable with traditional fuses.Please note that due to the inherent compromise involved between resistive vs. fusing performance it is recommended that prior consulta-tion be made with RCD’s engineering department to obtain the optimum design. Parts intended for high-reliability applications are available with burn-in (opt. ER) and/or military screening.PERFORMANCE CHARACTERISTICSFUSING CHARACTERISTICS: Standard FR resistors are designed to fuse within 10 seconds as follows:FR1/2 to FR2 ≥1Ω = 20 x W 25 (20 times the 25°C wattage rating), <1Ω = 40 x W 25. FR3 & FR5 ≥5Ω = 25 x W 25 , <5Ω = 50 x W 25.Faster fusing is available. Max. fault condition not to exceed 300x W 25. Following chart depicts custom design capabilities.* Other sizes available up to 50 Watt on a custom basis.APPLICATION & DESIGN NOTES:1. Fusing current should be ≥ 4 times the continuous current for best performance.2. Resistors reach elevated temperatures prior to opening- elevate body above the PCB.3. Exercise care when testing fuse resistors.4. RCD can custom manufacture fuse resistors from 1/8W to 50W per customer req’t. Design objectives are achieved by element material (wirewound or film), insulation (silicone, ceramic, epoxy), and process (alloy & resistor geometry).5. Thermal fuses are also available and are designed to “blow” when the resistor body or the ambient temperature reaches preset temperature (110°C to 240°C).6. Custom surge-tolerant fuses are designed not to “blow” due to short term voltage transients, lightning surges, or capacitor discharges, but will fuse under longer term overloads. Consult factory for details.7. Please include the following information when customized design is required: Continuous wattage or current; ambient temperature; fusing wattage or current; minimum and maximum “blow” times; resistance value & tolerance; max. size; voltage level, AC or DC, wave form, & frequency; and a general description of the application. Include info as to any pulse or overload conditions that the resistor must withstand.SPECIFICATIONSD C R *e p y T e g a t t a W W (C °52@52)ec n a t s i s e R e g n a R L ]1[40.±D ]5.[20.±d p y t 2/1R F 5.060.Ω005o t Ω]4.7[92.]2.3[521.]5.[020.1R F 0.11.0ΩK 5.1o t ]2.51[06.]3.3[031.]5.[020.2R F 0.21.0ΩK 2o t ]5.71[96.]3.4[071.]8.[230.3R F 5.31.0ΩK 3o t ]7.41[85.]8.5[032.]8.[230.5R F 5.51.0ΩK5o t ]52[489.]2.8[323.]8.[230.e c n a r e l o T e l b a l i a v a %01-1.0,d r a d n a t s %5e r u t a r e p m e T )p y t (t n e i c i f f e o C 9.-1.0m p p 001±Ω1m p p 05±,Ω,p u &mp p 01±o t e l b a l i a v a h t g n e r t S c i r t c e l e i D CA V 057e c n a t s i s e R n o i t a l u s n I )y r d (.n i m s m h o g e m 000,1gn i t a r e D @r e w o p d e t a r l l u f m o r f y l r a e n i l e t a r e D )C °/%76.(C °571@r e w o p o r e z o t C °52g n i s u F t n e rr u C )s e r e p m A (M s s e L r o .c e S 1n i e s u F o t e u l a V e c n a t s i s e R m u m i n i s s e L r o .c e S 5n i e s u F o t e u l a V e c n a t s i s e R m u m i n i M 2/1RF 1R F 2R F 3R F 5R F 2/1R F 1R F 2R F 3R F 5R F 51.0063Ω027ΩK 44.1K 88.2K 67.5081Ω063Ω027ΩK 44.1K 88.252.0021Ω042Ω084Ω069Ω0291Ω06Ω021Ω042Ω084Ω069Ω5.003Ω06Ω021Ω042Ω084Ω51Ω03Ω06Ω021Ω042Ω0.15.7Ω51Ω03Ω06Ω021Ω8.3Ω5.7Ω51Ω03Ω06Ω5.13.3Ω7Ω31Ω62Ω35Ω7.1Ω3.3Ω7Ω31Ω62Ω0.20.2Ω4Ω8Ω61Ω23Ω0.1Ω2Ω4Ω8Ω61Ω0.30.1Ω2Ω4Ω8Ω61Ω5.0Ω1Ω2Ω4Ω8Ω0.55.0Ω1Ω2Ω4Ω8Ω52.Ω5.Ω1Ω2Ω4Ω0152.0Ω5.Ω1Ω2Ω4Ω31.Ω52.Ω5.Ω1Ω2Ω5151.0Ω3.Ω6.Ω2.1Ω4.2Ω80.Ω51.Ω3.Ω6.Ω2.1Ω021.0Ω2.Ω4.Ω8.Ω6.1Ω60.Ω01.Ω2.Ω4.Ω8.ΩTORS CAPACITORS COILS DELA↑FA062A Sale of this product is in accordance with GF-061.
