10 Series
Axial Wire Element Current Sense
Four Terminal Axial
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 temperature coefficient of the terminals to be
effectively eliminated. The four terminal design
also results in a lower temperature coefficient of
resistance and lower self-heating drift which may be
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.
