APPLICATION CIRCUIT
APPLICATION NOTES
• 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.
