FC4T Series
Metal Foil Low Value Chip
The FC4T 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. Ohmite’s proprietary Metal Foil technology offers an excellent Temperature Coefficient of Resistance (TCR) even for very low resistance values ( down to 50ppm).
