FC4L Four Terminal Current Sense
Metal Foil Construction
F e at u r e s

•tFoil Construction ensures a very stable TCR
(Temperature Coefficient of Resistance)
•tDesigned for automatic insertion
•tIndustry standard sizes
•tHigh heat resistant use
•tLow heat electromotive use
•tColor: 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 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.
