SRU3028-101Y - Bourns

SRU3028-101Y Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the SRU3028-101Y?
  Bourns recommends a symmetrical PCB layout with a solid ground plane, and keeping the input and output traces as short as possible to minimize parasitic inductance and capacitance. A 4-layer PCB with a dedicated power plane and a solid ground plane is also recommended.
• How do I ensure the SRU3028-101Y is properly soldered and mounted on the PCB?
  Bourns recommends using a reflow soldering process with a peak temperature of 260°C (500°F) for 10-15 seconds. The device should be mounted on a PCB with a solder mask and a clearance of at least 0.5 mm around the device. A soldering iron with a temperature of 350°C (662°F) can also be used for manual soldering.
• What is the maximum operating temperature range for the SRU3028-101Y?
  The SRU3028-101Y is rated for operation from -40°C to 125°C (-40°F to 257°F), but derating is required for temperatures above 85°C (185°F). Consult the datasheet for specific derating curves.
• Can I use the SRU3028-101Y in a high-vibration or high-shock environment?
  Yes, the SRU3028-101Y is designed to withstand high-vibration and high-shock environments. It meets the IEC 60068-2-27 vibration test and the IEC 60068-2-29 shock test. However, it's recommended to consult with Bourns' application engineers for specific guidance on using the device in extreme environmental conditions.
• How do I troubleshoot issues with the SRU3028-101Y, such as output voltage instability or overheating?
  Common issues with the SRU3028-101Y can be caused by incorrect PCB layout, inadequate heat sinking, or incorrect input voltage. Consult the datasheet and application notes for troubleshooting guidelines, and contact Bourns' technical support for further assistance.
