By Ohmite 818
Ohmite's FC4T chip features four terminals also known as a Kelvin configuration enabling current to be applied through two opposite terminals and a sensing voltage to be measured across the other two terminals. This eliminates 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).
