The anti-jamming magnetic ring is part of the overall design of any electronic device and system. It is far more cost effective than other methods that try to make products reach EMC. EMC's main design techniques include: electromagnetic shielding methods, circuit filtering techniques, and grounding designs that include grounding components that should be specifically noted.

1. Application of good electrical and mechanical design principles

First, the foundation of an excellent EMC design is the application of good electrical and mechanical design principles. This includes reliability considerations such as the satisfaction of design specifications within acceptable tolerances, good assembly methods, and various test techniques being developed.

In general, devices that drive today's electronic devices are mounted on a PCB. These devices consist of components and circuits that have potential sources of interference and are sensitive to electromagnetic energy. Therefore, PCB EMC design is the next most important issue in EMC design. The location of the active components, the traces of the traces, the matching of the impedance, the design of the ground, and the filtering of the circuit should all be considered during EMC design. Some PCB components also need to be shielded.

2, the internal cable connection

Again, internal cables are typically used to connect PCBs or other internal subassemblies. Therefore, the internal cable EMC design, including the routing method and shielding, is important for the overall EMC of any given device.

After the EMC design of the PCB and the internal cable design are completed, special attention should be paid to the shielding design of the enclosure and the handling of all gaps, perforations and cable through-holes.

3, power and cable filters

Finally, you should also consider input and output power and other cable filtering issues.
