Current sense resistor is also known as Shunt resistor.
Chassis mount current sense resistor has test points at both ends to facilitate connection of a testing instrument. This resistor is generally available in very low ohmic high precision values (from less than 0.05Ω to 100kΩ), so that only a very few voltage drop caused. It is ideal in measuring circuits and Whetstone bridge type applications.
You may find that this resistor is designed to be physically mounted onto heatsinks or metal plates to further dissipate the generated heat. The mounting of the resistor onto a heatsink increases their current carrying capabilities even further.
