METAL FOIL/
KELVIN
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 FCSL 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 prod-
uct affords the user an added advantage of a built in 4-ter-
minal design with 2 larger electrodes for current manage-
ment and 2 smaller electrodes for current measurement.
