HIGH SPEED LAN MAGNETICS
960008A
• Quad, 4-port designs offer best design layout and per
port cost efficiencies
• Tested for use with multiple 10/100 Mbps and 100
Mbps PHY transceivers requiring 1:1 Tx and Rx
transformers
• Impedance matched common mode termination not
required
• Internal crossover design optimizes board layout for
use with stacked RJ-45 connectors
• Low profile, SMT packaging, rated to withstand 225ºC
peak IR reflow temperature
• 2000 Vrms isolation
