EMC Components ZCYS Series
Common Mode Choke Coils for Signal Line
SMD
FEATURES
• The ZCYS series common mode choke coils provide highly
effective noise rejection characteristics without distorting the
transmission signal. Especially, most available for USB interface
circuit.
• Well suited as a countermeasure against high-frequency radia-
tion noise in small signal interface lines, this product is a space-
efficient solution for multiple-line cable applications.
• A high level of miniaturization has been achieved with a maxi-
mum height of 2.5mm.
APPLICATIONS
Personal computers, telephones, LANs, ISDNs, digital PBXs, word
processors, electronic games, palm-sized computing devices,
CTVs, CD-ROM drives, 8mm video cameras.
