FC4L Series FC4L Four Terminal Current Sense Metal Foil Construction F e at u r e s •Foil Construction ensures a very stable TCR (Temperature Coefficient of Resistance) •Designed for automatic insertion •Industry standard sizes •High heat resistant use •Low heat electromotive use •Color: white (top) and green (bottom) Ohmite extends its FC4L Series with this 4-terminal Kelvin type FC4L derivative in 2 watt and 5 watt package sizes. Employing the same Ni-Cu-Mn resistive element this product affords the user an added advantage of a built in 4-terminal design with 2 larger electrodes for current management and 2 smaller electrodes for current measurement.
