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

Description
• Low insertion loss design for lower gain
dispersion in transceiver applications.
Features
• Compact and low profile (ideal for slimline sets)
• Low temperature coefficient and dispersion for
reliable response
• High selectivity
• Low spurious response
• Independent terminal structure
• Lead-free terminations
Applications
• Cordless telephones, tuner packs, radio cassettes,
car radios, compact portable radios
• Wireless data communication equipment
