CD143A-SR3.3 Frequently Asked Questions (FAQ)

  • A good PCB layout for the CD143A-SR3.3 involves keeping the input and output traces short and separate, using a solid ground plane, and placing the input and output capacitors close to the device. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.

  • To ensure the CD143A-SR3.3 operates within its specified temperature range, provide adequate heat sinking, avoid overcrowding the PCB, and ensure good airflow around the device. Additionally, consider using thermal interface materials and heat sinks to reduce thermal resistance.

  • To minimize EMI, use a shielded enclosure, keep the input and output cables short and twisted, and use EMI filters or common-mode chokes on the input and output lines. Additionally, consider using a metal can or shielded package for the CD143A-SR3.3.

  • The CD143A-SR3.3 is a commercial-grade device, but Bourns Inc offers high-reliability versions of the device that meet the requirements of aerospace and defense applications. Contact Bourns Inc for more information on their high-reliability products.

  • To troubleshoot issues with the CD143A-SR3.3, start by checking the input voltage, output voltage, and current. Verify that the device is properly soldered and that the PCB layout is correct. Use an oscilloscope to check for noise, ringing, or oscillations on the input and output lines.
