FC4L Series FC4L Four Terminal Current Sense Metal Foil Construction FeatureS Foil Construction ensures a ver y stable TCR (Temperature Coefficient of Resistance) Designed for automatic insertion 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 Industr y standard sizes achieved by employing a Ni-Cu-Mn resistive element. The High heat resistant use FC4L series affords the user an added advantage of a built in Low heat electromotive use 4-terminal design with 2 larger electrodes for current man- Color: white (top) and green (bottom) agement and 2 smaller electrodes for current measurement.
