Important notes at the end of this document.
Basic features
■ FPC is a composite material of polymer and ferrite
■ FPC film is a thin, mechanically flexible film
Technical benefits
■ Stable magnetic characteristics
■ Low weight: FPC film is 40% lower in density than ferrite
■ High mechanical strength
■ Shaping as required: customer-specific solutions possible
■ Economy: easy transport and storage,
simple, rationalized processing, low mounting volume
■ C351 film suitable for high-temperature applications (up to 200 qC)
■ Material C351 approved to UL 94-V0 (E 140 693)
■ Various film thickness (from 0.2 to 0.4 mm), thickness tolerance r15%
■ Self-adhesive versions (limited shelf life)
Applications
■ Implementation of low-profile coils, e.g. for
– identification systems
– security tags for electronic article surveillance
– sensors
– inductive reading of smart cards
■ Electromagnetic shielding of coils from metals to prevent interference
■ EMC: absorption of radiated emissions at frequencies t500 MHz
■ Compensation of deflection yokes to correct distortion at the corners of TV screens and monitors
■ Spacing between ferrite cores (as a substitute for air gaps or non-magnetic films) for
– suppression of the leakage field
– adjustment of the biasing curve
