CIT-A Series
Transformers
For Modem
SMD, PC Card, Pin Terminal
FEATURES
• SMD, pin-terminated, and PC Card (PCMCIA, TYPE-II) are
available for ITU-T V.32bis (14,400bps) and V.22bis (2400bps)
applications.
• The bobbin features a double insulation structure.
• The wire terminations and soldering terminals are physically
separate. This prevents wire breakage or pin lifting during the
mounting/soldering process.
• The use of TDK ferrite cores results in a maximum thickness of
4.3mm, making these transformers suitable for PC Card use.
