1224 SMD電阻- 1224 0.003ohm 1%

Four Terminal High Precision Current Sense

Current sense resistors enable the measurement of current flow

in a circuit by monitoring a voltage drop across a precisely 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

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.

Isolating the voltage and current terminals (see schematic)

facilitates a very accurate current measurement. 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 environments.
