non-PoE transformer

From the center tap, Bob Smith terminal to PCB layout, the system sorts out the most common pitfalls of the Ethernet port, and provides selection suggestions based on VOOHU full-rate network transformers and supporting components.

The network port function and EMC have passed, but it is stuck in the final Hi-Pot voltage test? Starting from the isolation nature of Ethernet transformers, VOOHU dissects the real causes of sparking and excessive leakage current (center tap capacitor withstand voltage, PCB creepage distance, GDT malfunction), and provides a safety selection table for isolation voltage withstand voltage of 1500V~5000V full-range network transformers and integrated magnetic RJ45.
