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.
