Common Mode Choke Coils for Signal Line
SMD
FEATURES
• A common mode filter for distortion-free noise removal from
transmitted signals. Optimized for transmission of high quality
signals.
• Best filter for countering the common mode noise resulting from
data signal processing by PCs, phone equipment, etc.
• SMD-type designed for surface mounting.
• Due to a maximum current tolerance of 5A, can also be used to
counter power line noise.
• The ZJYS81R5-2PL is a high inductance common mode filter
designed to use with a CAN-BUS.
• The “T” designation at the end of the product code indicates
tape mounting.
ZJYS Series ZJYS51, ZJYS81 Types
APPLICATIONS
Personal computers, telephones, LANs, ISDNs, digital PBXs, elec-
tronic games, CTVs, CD-ROM drives, 8mm video equipment, and
other electronic devices.
