APPLICATION & DESIGN NOTES:
1. Fusing current should be
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.
5. Thermal fuses are also available and are designed to “blow” when the resistor body or
6. Custom surge-tolerant fuses are designed not to “blow” due to short term voltage

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.
