Low Cost Circuit Protection!
RCD pioneered fusible film resistors in the early 1970’s as a
low cost approach to circuit protection in case of overload or
component failure. The component is designed to act as a
conventional resistor under normal operating conditions, but
open quickly under fault conditions. Series BW meets the
requirements of EIA RS-325 and can be useful in eliminating
circuit board damage and fire hazards. Standard fusing
characteristics can be altered to customer requirements.
OPTIONS
Modified fusing characteristics (fast blow, slow blow, etc.)
Increased pulse capability (Option P)
Dozens of additional options are available...
Mil-spec screening/burn-in, special marking, non-standard
values, custom lead forming, increased power or voltage, etc.
Customized components are an RCD specialty!

APPLIED POWER (WATTS)
APPLICATION NOTES:
1. Fault level must be suitable to safely open the resistor quickly, especially surface mount
MBW models. If insufficent, the resistor may reach elevated temp. For this reason, the
fusing overload must be relatively large compared to rated W, 20 to 50x is common for
most axial-lead applications, 40 to 100x for most SM circuits. SM fusing times vary due to
mounting geometry/materials, so each application needs to be evaluated by user. The fault
condition must be at least equal to the minimum W indicated in each of the above curves,
and preferably double for SM applications. Fusing may still occur at W levels below the
levels graphed above but not consistently (fast-blow models available). Don’t exceed volt
rating or 200x W rating, whichever is less (increased levels available).
2. For customized models, complete RCD’s Fuse Questionnaire or advise the desired fusing
wattage or current, min.& max. blow time, continuous wattage, ambient temp., pulse
conditions, physical constraints, voltage to be interrupted, frequency, etc.
3. Maintain clearance from any heat-sensitive or flammable materials.
4. Fusing times vary depending on resistance value. Typical fusing times are given above
for 1Ω - 3.9K. Low values tend to fuse slower. Consult factory for assistance.
5. Residual resis. is
≥50x
initial value after fusing at 20x rated W (30x for BW1/8F & MBW)
6. Verify selection by evaluating under the full range of fault conditions. Place resistors
inside a protective case when testing.
