FEATURES:
Industry’s widest range of 4-terminal power resistors!
Standard tolerances to 0.1%, TC’s to 5ppm
Welded & fireproof construction
Available on exclusive SWIFT^TM delivery program!
4-terminal “Kelvin” design eliminates contributing error
due to lead resistance
Standard current ratings to 40A (up to 100A on custom basis)
For surface mount design up to 3W see SF series
Four-Terminal Current Sensing as low as 0.0005Ω
RCD’s Series LVF resistors feature a 4-terminal “Kelvin”
design to eliminate the effects of lead resistance. Precision
resistive element is potted inside a ceramic case for excellent
durability and environmental protection. Series LVF resistors
are well-suited for current sensing applications including test
instrumentation, power supplies, and power amplifiers.
Specify option E when circuits require low thermal EMF.
OPTIONS:
Option X: Non-inductive design
Option E: Low thermal EMF design
Numerous other options available including custom
marking, lead forming, lead diameter, burn-in, etc.

SUGGESTED MOUNTING
Bend leads approximately 1/8” from body. If operating at or
near rated power, standoffs are suggested to prevent
overheating of the PCB. Utilize heavy duty copper traces
adequate for intended current levels.
