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.
