FCSL Series
Metal Foil Current Sense
Ohmite continues to add to its complement of
Current Sense offerings with the FCSL Series. FCSL
incorporates proven metal foil technology to pro-
duce the ultimate in a current sense resistor. FCSL
features the effective combination of very low and
stable TCRs (Temperature Coefficient of Resistance)
available in a wide selection of very low ohmic val-
ues. Power ratings up to 5 Watts makes FCSL the
ideal choice for your current sensing applications.
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)
