APPLICATION NOTES
• These Bel part types have been designed for use in 100 Mbps TP-FDDI, 100Base-TX, 10/100Base-TX and ATM
155 Mbps applications over Category 5 UTP or STP cable.
• Each Bel part type is designed with high voltage isolation transformers and common mode chokes and can be
used on both the transmit and receive channels. The designs have been created to provide 350µH OCL with 8mA
DC bias applied. Consult the Bel short form catalog and applicable application circuit for the specific configuration
of each individual part type.
• Bel's low profile, surface mount packaging is ideal for high speed pick and place machinery. Parts can be shipped
on tape and reel for high speed placement. Construction processes have been implemented for thermal compatibility
with high temperature IR reflow assembly processing. Post dipping of leads assist with PC board solderability.
Each part is optically inspected to meet rigid coplanarity requirements.
