Precision Resistor Co., Inc. Percision Wire Wound Power Shunt Resistor - Rectangular Axial PLV Series

4-Terminal Rectangular Axial Precision Power Shunt - PLV Series Features: Lower self-heating-Low temperature rise per watt, Low TCR, and Low EMF for greater thermal stability Durable-Excellent overload and surge current handling capabilities. Dependable and repeatable measurements under load-Without this feature the voltage drop across a low value element will no longer be a linear function of current. Thru-Hole or SMD Designs- are ideal in amplifier circuits and accurate voltage drop applications. They also offer excellent thermal transfer to base and better overload and surge current handling capabilities Hot-Tinned Copper Terminals-for better solder wetting, longer shelf life and higher current-carrying capacities. Lower Ohmic Values-to one milliohm (0.001) ... and closer resistance tolerances to ±0.005%. Very Low TCR Characteristics-0±15 ppm (Standard) and Special TCRs to 0±10ppm for operation over a wider temperature span and provide greater stability under load Low Thermal EMF Construction - 1microvolt/°C. with respect to the copper terminals. This low EMF construction together with PRC's "single-joint" 4-terminal design will eliminate "lead-out" resistance variations, contact resistance and annoying thermal electric effects generally associated with very low resistance values. Premium Parts-All these design features combined enable all our parts to perform flawlessly, to ensure your precision application will do the same.
