FAILSAFE FUSE RESISTORS
1/2 WATT to 50 WATT
FR SERIES
Precision 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, emitter
resistors 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 CHARACTERISTICS
FUSING 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), <1
Ω = 40 x W
25.
FR3 & FR5
≥5Ω = 25 x W
25 , <5
Ω = 50 x W
25.
Faster fusing is available. Max. fault condition not to exceed 300x W25. 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.
