Industry’s widest range of 4-terminal power resistors! Standard tolerances to 0.1%, TC’s to 5ppm Welded & fireproof construction Available on exclusive SWIFTTM 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.
