Industry’s broadest range of fusible chip resistors-
7 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)
FUSIBLE CHIP RESISTORS
FC SERIES
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.

Fault level must be suitable to safely open the resistor. 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).
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.
Customers should evaluate fusing in actual-use conditions.
Exercise care when testing fuse resistors.
