60 Series Four Terminal Bare Element Ohmites Four Terminal Bare Element Resistors provide ultra low resistance values (to 0.0005) for relatively high current requirements, with the advantages of a Kelvin configuration and PC Board mounting capability. These shunt resistors are specifically designed for low resistance applications requiring the highest accuracy FeatureS and temperature stability. This Four Terminal version of Ohmites 60 Series Resistor is specially designed for use Ideal for current sensing applications in a Kelvin configuration, in which a current is applied 1% tolerance standard, others available through two opposite terminals and sensing voltage is Low inductance (non-inductive below measured across the other two terminals. 0.05) The Kelvin configuration enables the resistance and temperature coefficient of the terminals to be effectively RoHS compliant eliminated. The four terminal design also results in a Radial, self-supporting, design is ideal for lower Temperature Coefficient of Resistance and lower PC board mounting self heating drift which may be experienced on two ter- High Power-to-size ratio minal resistors. The requirement to connect to the ter- minals at precise test points is eliminated, allowing for Decimal marked, silicone coated (650 tighter tolerancing on the end application.
