What factors should be considered when selecting EMI filters for a system?

When selecting EMI filters for a system, consider factors like the type and level of electromagnetic interference the system encounters. Understanding the frequency range of the interference is crucial for choosing the right filter design. Evaluate the system's voltage and current ratings to ensure compatibility with the filter's specifications. The environment, such as industrial or residential settings, also impacts the filter's requirements. Space constraints and ease of installation should be considered, especially for compact systems. Additionally, certifications and compliance with regulatory standards ensure reliable performance. Choosing the right EMI filters enhances device functionality and minimizes electromagnetic interference effectively.
