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. The S558-

5999-90 also includes an impedance matched common mode termination. For background details concerning the

proper implementation or complete elimination of this termination circuit, please request Bel's separate application

note available on this subject. All designs have been created to provide 350µH OCL with 8mA DC bias applied.

Consult the Bel short form catalog and recommended application circuit for the specific configuration of each

individual part type.

• The surface mount packages are designed 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.
