FC4L 4-Terminal Current Sense SMD Resistors

Ohmite FC4L 4-Terminal Current Sense Resistor Series includes 0.25W, 1W, 2W, and 5W packages. Ohmite has extended its FCSL Series product line with the 4-terminal, foil-type FC4L Series Current Sense SMD Resistors. The FC4L Series resistors from Ohmite have a foil construction that ensures a very stable TCR (Temperature Coefficient of Resistance) in a 5W package. In addition, FC4L resistors have a built-in Kelvin connection and 4-terminal design, which includes 2 larger electrodes capable of carrying large currents and 2 smaller electrodes for current measurement.
