Basic features

I FPC is a composite material of polymer and ferrite

I FPC film is a thin, mechanically flexible film

Technical benefits

I Stable magnetic characteristics

I Low weight: FPC film is 40% lower in density than ferrite

I High mechanical strength

I Shaping as required: customer-specific solutions possible

I Economy: easy transport and storage,

simple, rationalized processing, low mounting volume

I C351 film suitable for high-temperature applications (up to 200

°C)

I Material C351 approved to UL 94-V0 (E 140 693)

I Various film thickness (from 0,2 to 0,4 mm)

I Self-adhesive versions

I C351 film with optional copper coatings 35 to 75

µm thick

Applications

I Implementation of low-profile coils, e.g. for

– identification systems

– security tags for electronic article surveillance

– sensors

– inductive reading of smart cards

I Electromagnetic shielding of coils from metals to prevent interference

I EMC: absorption of radiated emissions at frequencies

≥ 500 MHz

I Compensation of deflection yokes to correct distortion at the corners of TV screens and monitors

I 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
