The CST0612 is a new four-terminal current sense resistor from Bourns that comes in a miniature 0612 size footprint.
It offers low resistance values of 0,5 m to 2 m and can handle a maximum power rating of up to 1 W.
Current sense resistors are growing in popularity due to their high measurement accuracy and relatively low cost compared to other technologies. These resistors detect and convert current to an easily measured voltage which is proportional to the current through the device.
The four-terminal design of the CST0612 series allows for high-precision four-wire (also known as Kelvin) resistance measurement. Its metal alloy current sensing element allows for low thermal EMF and temperature coefficient of resistance (TCR).
