This four-terminal version of Ohmites 10 Low Inductance (non-inductive below 0.25) Series resistor is specially designed for use in a Kelvin configuration, in which a current is applied Tinned Copper Leads through two opposite terminals and sensing voltage RoHS Compliant is measured across the other two terminals . The Kelvin configuration enables the resistance SerieS SpeCiFiCationS and temperature coefficient of the terminals to be Series Wattage Ohms effectively eliminated. The four terminal design 13 3 0.005-0.1 also results in a lower temperature coefficient of 14 4.5 0.005-0.1 resistance and lower self-heating drift which may be 17 7 0.005-0.1 experienced on two-terminal resistors. The require- ment to connect to the terminals at precise test points is eliminated, allowing for tighter tolerancing on the end application.
