MKW20-12S12M Frequently Asked Questions (FAQs)

  • The recommended PCB layout involves placing the module on a 4-layer PCB with a solid ground plane, using thermal vias to dissipate heat, and keeping the surrounding components at a safe distance. A heat sink or thermal pad can be added to improve thermal management.
  • To ensure EMC, follow proper PCB design guidelines, use shielding, and keep sensitive components away from the module. Additionally, use a common mode choke or ferrite bead to filter out noise on the input lines.
  • The maximum allowable ripple voltage on the input is typically 10% of the nominal input voltage. Exceeding this value may affect the module's performance and reliability.
  • The MKW20-12S12M is designed for general industrial applications, but it may not be suitable for high-vibration or high-shock environments. If your application requires such conditions, consider using a module with specific vibration and shock ratings or consult with the manufacturer for custom solutions.
  • The typical efficiency of the MKW20-12S12M is around 85-90% at full load. Efficiency may vary with load, with a slight decrease at lower loads. Consult the datasheet or manufacturer for detailed efficiency curves.
