What are some low-cost EMC optimization solutions for power FTUs?

FTU's low-cost EMC optimization reduces costs while maintaining performance. The solution includes:

1. Using integrated filter connectors to reduce discrete filters;

2. Replacing expensive inductors with PBZ1608E600Z0T surface-mount ferrite beads;

3. Optimizing PCB layout to reduce shielding;

4. Replacing some hardware filters with software filtering;

5. Replacing imported components with high-quality domestic ones, such as using CMZ series common-mode inductors from Etymotic.

Through optimization, EMC costs are reduced by more than 30%, while meeting the requirements of GB/T 17626 and GB/T 9254 standards, significantly improving cost-effectiveness.
