IT143 datasheet by Schaffner

IT143 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the IT143?
  Schaffner recommends a symmetrical PCB layout with a solid ground plane and a minimum of vias to ensure low inductance and optimal performance. A reference design is available upon request.
• How do I ensure the IT143 is properly soldered to the PCB?
  Schaffner recommends using a soldering profile with a peak temperature of 260°C (500°F) and a dwell time of 30-60 seconds. Additionally, ensure the PCB is clean and free of oxidation to ensure a reliable solder joint.
• What is the maximum operating temperature range for the IT143?
  The IT143 is designed to operate from -40°C to 125°C (-40°F to 257°F), but derating may be necessary for high-temperature applications. Consult Schaffner's application notes for more information.
• Can the IT143 be used in high-vibration environments?
  Yes, the IT143 is designed to withstand high-vibration environments. However, it's essential to ensure the component is properly secured to the PCB and the PCB is mounted securely to the chassis to prevent mechanical stress.
• How do I troubleshoot common issues with the IT143, such as overheating or malfunction?
