PM2120-821K-RC - Bourns

PM2120-821K-RC Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Bourns recommends a symmetrical PCB layout with a solid ground plane to minimize electromagnetic interference (EMI) and ensure optimal performance. A minimum of 2 oz copper thickness is recommended for the PCB.
• How do I ensure reliable soldering of the PM2120-821K-RC?
  To ensure reliable soldering, Bourns recommends using a soldering iron with a temperature range of 250°C to 260°C, and a solder with a melting point of 180°C to 200°C. The component should be soldered within 3 seconds to 5 seconds to prevent thermal damage.
• What is the maximum operating temperature range for the PM2120-821K-RC?
  Although the datasheet specifies an operating temperature range of -40°C to 125°C, Bourns recommends derating the component's power rating by 1.5% per degree Celsius above 85°C to ensure reliable operation.
• Can I use the PM2120-821K-RC in a high-vibration environment?
  Yes, the PM2120-821K-RC is designed to withstand high-vibration environments. However, Bourns recommends securing the component to the PCB using a suitable adhesive or mechanical fastening method to prevent damage or dislodging.
• How do I handle electrostatic discharge (ESD) protection for the PM2120-821K-RC?
  Bourns recommends handling the PM2120-821K-RC with ESD-protective equipment and following proper ESD-handling procedures to prevent damage. The component should be stored in an ESD-protective package or bag when not in use.
