What are some low-cost EMC optimization solutions for concentrators?

While ensuring the basic EMC performance of the concentrator, low-cost EMC optimization can be achieved through optimized design and selective component use. Solutions include: prioritizing optimized PCB layout and grounding, a zero-cost but highly effective measure; selectively using filtering components: locally adding ferrite beads (PBZ series) and capacitors near noise sources (such as switching power supply outputs) and sensitive circuit entry points (such as ADC inputs); using connectors with integrated filtering and protection functions, which may be more economical than separate designs; implementing digital filtering and fault-tolerant algorithms in software to replace some hardware filtering; selecting cost-effective domestic EMC components, such as the CMZ, CML, and PBZ series from Yinte Electronics; conducting thorough pre-testing to accurately locate out-of-specification points and avoid blindly adding components; and replacing expensive shielding materials through structural design (such as utilizing the casing itself for shielding). These measures can ensure the concentrator meets mainstream EMC standards while controlling costs.
