FC4L Series Datasheet

FC4L Four Terminal Current Sense Metal Foil Construction

Features

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 offers the low TCR FC4L series in 0.25 watts up to 5 watts and values down to 1 milli-ohm. Great stability is achieved by employing Ni-Cu-Mn resistive element. The FC4L series 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.
