APPLICATION NOTES • These Bel part types have been designed for use in 100 Mbps or 10/100 Mbps data transmission systems over category 5 UTP/STP cable. Each Bel part type provides superior EMI noise suppression, high voltage isolation, wave shaping and fast, but controlled rise times. All parts meet IEEE 802.3 standards, which includes 350µH OCL (inductance) when 8mA of DC bias is applied. • Implementation of these part types with the QS6611 can be achieved and requires higher current created by changing the 5 volt resistors from 86ý to 100ý and the IREF resistor from 4.53Ký to 4.75Ký. • 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. Specifications subject to change without notice.
