TOKEN LSQ Open Air Current Sense Resistors Kelvin Four Terminal Resistors Token (LSQ) Family Four Terminal Resistors handle high-wattage applications Preview Providing ultralow resistance values (to 0.01 ohm) for relatively high current requirements, new four-terminal cement filling resistors from Token combine the advantages of a Kelvin configuration with PC board mounting capability. The Kelvin (or four-terminal) configuration enables current to be applied through two opposite terminals and a sensing voltage to be measured across the other two terminals, eliminating the resistance and temperature coefficient of the terminals for a more accurate current measurement. The four terminal resistors are a new version of Token’s (LSQ) Current Sense Family Series which was specially designed for use in a Kelvin configuration where a current is applied through two opposing leads and sensing voltage is measured across the other two leads. Token LSQ series is specifically designed for low resistance applications requiring the highest accuracy and temperature stability. The advantages of Kelvin configuration enable the resistance and temperature coefficient of the leads to be effectively eliminated. The need to connect to the leads at precise test points is eliminated, allowing for tighter tolerance on the end application. Also results in a lower temperature coefficient of resistance and lower self-heating drift which may be experienced on two-terminal resistors. Token will also produce low ohm resistor LSQ series outside these specifications to meet customer requirements. Contact us with your specific needs.
