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 resis-
tor. 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 4 Watts makes FCSL the ideal choice for your current sensing
applications.
FeaTuReS
• 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)
