EMC-20 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal EMI performance?
  CUI recommends a multi-layer PCB with a solid ground plane, and to keep the input and output traces as short as possible. Additionally, it's recommended to use a common mode choke and to route the input and output cables away from each other.
• How do I ensure the EMC-20 meets my specific regulatory requirements?
  CUI recommends consulting the relevant regulatory standards (e.g. EN 55022, FCC Part 15, etc.) and performing testing to ensure compliance. Additionally, CUI can provide guidance on design and testing to help meet specific regulatory requirements.
• What is the maximum operating temperature range for the EMC-20?
  The EMC-20 is rated for operation from -40°C to +85°C, but derating may be required for high-temperature applications. Consult the datasheet and CUI's application notes for more information.
• Can I use the EMC-20 in a high-vibration environment?
  Yes, the EMC-20 is designed to withstand vibrations up to 10G, but it's recommended to consult CUI's application notes and perform testing to ensure reliability in specific high-vibration environments.
• How do I troubleshoot EMI issues with the EMC-20?
  CUI recommends using a spectrum analyzer to identify the frequency of the EMI issue, and then using techniques such as shielding, filtering, and layout optimization to mitigate the issue. Consult CUI's application notes and technical support for guidance.
