Ohmite’s Four-terminal Current-sense Resistors are specifically
designed for low-resistance applications requiring the highest
accuracy and temperature stability. This four-terminal version
of Ohmite’s 10 Series resistor is specially designed for use in a
Kelvin configuration, in which a current is applied through two
opposite terminals and sensing voltage is measured across the
other two terminals .
The Kelvin configuration enables the resistance and tempera-
ture coefficient of the terminals to be effectively eliminated. The
four terminal design also results in a lower temperature coef-
ficient of resistance and lower self-heating drift which may be
experienced on two-terminal resistors. The requirement to con-
nect to the terminals at precise test points is eliminated, allowing
for tighter tolerancing on the end application.
