Current sense resistors

21 March 2018 Passive Components

The FC4T chip resistor series from Ohmite features four terminals, in what is 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.

Ohmite’s proprietary metal foil technology offers an excellent temperature coefficient of resistance (TCR) even for very low resistance values (down to 50 ppm). The resistors come in a 1206 chip package with a 0,5 W power rating, and are offered in values from 5 to 100 mΩ and tolerances of 1% or 0,5%.

Power management, over-current protection and voltage regulation modules are among the potential applications of FC4T current sense resistors.
