CFSKNG Datasheet, PDF (1/1 Pages) TOKO, Inc – FM CERAMIC FILTERS

Description
• High grade filters controlling 0.5μS bandwidth.
Features
• Compact and low profile (ideal for slimline sets)
• Low temperature coefficient and dispersion for
reliable response
• High selectivity for excellent spurious response control
• Low spurious response
• Independent terminal structure
• Lead-free terminations
Applications
• Especially suited for digital cordless telephones
and high grade stereo sets.
• MIDI audio systems and car stereo
• Digital telecommunications equipment
