• 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 part type provides high voltage isolation, wave shaping, superior EMI and noise suppression and fast rise times. All parts meet IEEE 802.3, ANSI X3T9.5 and ATM Forum Committee standards.
• Each Bel part type is designed with high voltage isolation transformers and common mode chokes. The S558-5999- 43 and -44 also contain an impedance matched common mode termination. For background information on the proper implementation or complete elimination of this termination consult Bel's separate application note available on this subject. All designs have been created to provide 350H OCL (inductance) with 8mA DC bias applied. Consult the Bel short form catalog and recommended 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  ith high temperature IR reflow assembly processing. Post dipping of leads assist with PC board solderability. Each  art is optically inspected to meet rigid coplanarity requirements.
