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 produce 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 values. 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)
