PRC manufactures a comprehensive line of precision wire wound current sensing shunts in both surface mount and through-hole packages. Shunts are low-value precision resistors used to measure current flow by producing a known voltage drop proportional to the current passing through them.<\/p>

Our shunts are distinguished by their low EMF construction, pure copper terminals, low self-heating, and 4-terminal Kelvin measurement capability.<\/p>

Applications include battery management systems, power supply monitoring, motor drive current sensing, amplifier circuits, process control instrumentation, and precision metering. PRC offers values down to 1 milliohm (0.001\u03a9) with tolerances to \u00b10.005% and TCRs to 0\u00b115 ppm\/\u00b0C, delivering dependable and repeatable current measurements under load.\u00a0<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

4-Tab SMD Current Sensing Shunts<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

The LVS series is PRC\u2019s signature surface mount shunt, widely recognized for its 4-tab Kelvin configuration that eliminates solder joint and PCB trace resistance from the current measurement. Available in power ratings from approximately 1W to 5W+ (at 25\u00b0C), the LVS series uses a rectangular, solvent-resistant epoxy case that provides excellent thermal transfer to the PCB. Solderable hot-tinned pure copper tab terminals deliver low EMF construction and high current-carrying capacity.

Standard TCR is 0\u00b115 ppm\/\u00b0C, with a lower TCR option of 0\u00b110 ppm\/\u00b0C available (add \u201cLTC\u201d suffix to part number). The Low Temperature Coefficient option is sustainable when the combined temperature of self-heating and ambient operating temperature does not exceed +150\u00b0C. Stability is \u00b10.001%\/year at +25\u00b0C with no load. Available in tape-and-reel packaging for automated SMD assembly.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

The PLV series provides 4-terminal Kelvin measurement capability in a through-hole axial lead package, available in 1W, 3W, and 10W+ configurations (PLV1, PLV3, PLV10). These shunts are designed for applications requiring higher power handling than SMD packages can accommodate, while still eliminating lead resistance from precision current measurements.

Key design features include low self-heating (low temperature rise per watt), low TCR and low EMF for thermal stability, and excellent overload and surge current handling capabilities. The PLV series is ideal for amplifier circuits, precision voltage drop applications, and high-accuracy current sensing in industrial and instrumentation systems. The durable rectangular epoxy case offers excellent thermal transfer to the mounting surface.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
