Surface Mount Circuit Protection!
RCD Series FC resistors offer a low cost approach to
circuit protection in case of overload or component failure.
The resistor is designed to act as a conventional resistor
under normal operating conditions, but will quickly open
under continuous overload. Standard fusing characteris-
tics can be altered to customer requirements.

APPLICATION NOTES:
1. Fuse resistors may reach elevated temperatures prior to
opening, particularly if subjected to insufficient overloads.
Customers should evaluate product for suitability under
all possible overload scenarios.
2. Exercise care when testing fuse resistors, i.e. place the
resistors inside a flameproof protective case, etc.
3. Fusing time varies depending on the amount of “heat sinking”
involved, i.e. PCB material, pad size, trace thickness, etc.
Customers should evaluate fuse resistors in actual-use
conditions. Modified fusing characteristics are available.
