Designed within each module are transmit and receive filter networks, high voltage isolation transformers and high performance EMI suppression common mode chokes. Each module fully meets the IEEE 802.3 standards for 10 Mbps data rates over 100 meters of media cable. • This Bel part type has been designed to provide signal performance optimization, maximum noise reduction and minimum crosstalk interference. Careful board layout and grounding techniques are also critical to control jitter and signal reflections. • 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.
