APPLICATION NOTES

APPLICATION CIRCUIT

· All designs meet IEEE 802.3 standards.

· Additional common mode chokes are available in separate packaging.

· Quad designs with integrated transmit and receive transformers, with or without common mode chokes, are

available.

· 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.
