APPLICATION NOTES
• These parts have been developed for use with multiple IC transceivers for 100Base-T4 category 3, 4, or 5 UTP cable
applications. There are multiple design options available for optimization of the specific application.
• 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.
