2.13 RJ45 Integrated Network Transformer Lightning Protection Scheme
Advantages of the solution: To meet the dual requirements of compact PCB layout and electrostatic surge protection, this solution selects the FC62115BNL-LM integrated network transformer interface and combines it with the anti-static component ULC332010T8. While achieving efficient use of space, it can effectively ensure the signal integrity of the network port. The protection performance of this solution fully complies with international standards: it meets the IEC61000-4-2 Level 4 standard, can withstand contact discharge of 30kV and air discharge of 30kV electrostatic shocks; it conforms to the IEC61000-4-5 standard, can resist surge shocks of 8/20μs waveform and 20A, and builds a reliable defense line for the stable operation of the network port in harsh environments.
