Current sense resistors enable
the measurement of current
flow in a circuit by monitoring
a voltage drop across a pre-
cisely calibrated resistance.
The LVK chip features four
terminals, also known as a
“Kelvin” configuration. This
configuration enables current
to be applied through two
opposite terminals and a sens-
ing voltage to be measured
across the other two terminals,
eliminating the resistance and
temperature coefficient of the
terminals for a more accurate
current measurement.
and current terminals (see
schematic) facilitates a very
accurate current measure-
ment. Ohmite’s proprietary
technology offers an excellent
Temperature Coefficient of
Resistance (TCR) even for
very low resistance values.
The resistive element consists
of a durable, anti-corrosive
metal alloy that combines
reliable performance with the
ability to withstand harsh envi-
ronments.
