FUSIBLE CHIP RESISTORS RESISTORS w COILS w DELAY LINES FC SERIES L T t FEATURES W r Industry's widest range of fusible chip resistors! r Perform like conventional chip resistors under normal conditions but fuse when subject to overloads r 7 standard sizes from 0402 to 2512 r Wide resistance range: 1 to 10K standard 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 characteristics can be altered to customer requirements.

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.
