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.

ꢀ 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^TMdelivery program

ꢀ Custom design available for increased surge capability

(specify Option P)

ꢀ Also available: Hi-Rel screening, burn-in, custom marking, etc.

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.

FUSING CHARACTERISTICS: Standard FR resistors are designed to fuse within 10 seconds as follows:

FR1/2 to FR2 ≥1Ω = 20 x W₂₅(20 times the 25°C wattage rating), <1Ω = 40 x W_25.FR3 & FR5 ≥5Ω = 25 x W₂₅, <5Ω = 50 x W_25.

Faster fusing is available. Max. fault condition not to exceed 300x W₂₅. Following chart depicts custom design capabilities.

APPLICATION & DESIGN NOTES:

P/NDESIGNATION:

FR1

- 101 - J B

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.
