Utilization of the S553-3873-23 with the BCM 5000 requires additional differential filtering placed as discrete components externally on the PCB layout. Bel can provide information regarding the required circuit and component values. Both of these Bel parts can be used in 100Base-T4 adapter card or multi-port repeater applications with category 3, 4 or 5 UTP/STP media cable. • 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.
