ZJY Series
Common Mode Choke Coils for Signal Line and DC Power Line
DIP
FEATURES
• A common mode filter for distortion-free removal of noise from
transmitted signals. Best common mode filter for transmission of
high quality signals.
• Best filter for countering the common mode noise resulting from
data signal processing by PCs, phone equipment, etc.
• Highly appropriate for IC board mounting due to DIP type struc-
ture.
• Due to a maximum current tolerance of 3A, can also be used to
counter power line noise.
APPLICATIONS
Personal computers, telephones, LANs, ISDNs, digital PBXs, elec-
tronic games, CTVs, CD-ROM drives, 8mm video equipment, and
other electronic devices.
