SF SERIES
RoHS
ꢀ Industry’s widest range! Values from .001Ω-5KΩ,
tolerances to ±0.01%, TC’s to 5ppm, 1W to 3W
ꢀ Excellent for current sensing applications
ꢀ Available on exclusive SWIFTTM delivery program!
RCD’s Series SF resistors feature an all-welded “Kelvin” 4-
terminal design in a surface mount package, reducing the
effects of lead resistance. High -temperature case provides
excellent environmental protection. Series SF utilizes the
same technology as our popular Series LVF leaded
resistors with over 30 years of proven experience.
OPTIONS
ꢀ Option X: Low inductance design
ꢀ Option P: Increased pulse capability
ꢀ Option E: Low thermal EMF design
ꢀ Also available: burn-in, leaded version, custom-marking,
increased current rating, matched sets, etc.
