Each module includes a 400 ohm transmit and 100 ohm receive filter, impedance matched to the Microlinear chipset for signal shaping, high voltage isolation transformers, and center taps for grounding. An optional common mode choke is available for further EMI and noise suppression. • 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.
