FUSIBLE CHIP RESISTORS FC SERIES RESISTORSCAPACITORSCOILSDELAY LINES RoHS Term.W is RoHS compliant & 260°C compatible T t Industry’s broadest range of fusible chip resistors7 standard sizes from 0402 to 2512, widest resistance range- 1Ω to 10K standard Perform like conventional chip resistors under normal conditions but fuse when subject to overloads Standard tolerance: ±5%,10% (1%,2% available) See MBW Series for additional SM fuse resistors (1/4W-3W) W 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 when subjected to suitable continuous overload. Standard fusing characteristics can be altered to customer requirements.

If insufficient the resistor may reach elevated temp. For this reason, the fusing load must be relatively large compared to rated W, 30-60x is common for most circuits, and should be at least equal to the minimum fusing power listed in Performance Chart. Fusing may still occur at W levels below these but not as consistently (fast-blow models available). 2) Don’t exceed volt rating or 200x W rating, whichever is less. Customers should evaluate product for suitability under all possible overload scenarios. Customized fusing characteristics are available. Fusing times vary depending on the amount of “heat sinking” involved, i.e. PCB material, pad size, trace thickness, etc. 3) Customers should evaluate fusing in actual-use conditions. Exercise care when testing fuse resistors. CONSTRUCTION Environmental Seal Fusible Resistive film Marking available (specify Opt.
