Bourns provides a recommended PCB layout and land pattern in their application note AN204, which can be found on their website. It's essential to follow these guidelines to ensure proper performance and reliability.
The SDR1105-270ML has a high power rating, and thermal management is crucial. Ensure good airflow, use a heat sink if necessary, and follow the thermal derating guidelines in the datasheet. You can also consult Bourns' application note AN205 for more information.
Bourns recommends using a reflow soldering process with a peak temperature of 260°C (500°F) for a maximum of 20 seconds. Hand soldering is not recommended due to the device's high power rating and small size.
While the SDR1105-270ML is a robust device, it's essential to ensure that the PCB and component are properly secured to withstand vibrations. Consult Bourns' application note AN206 for guidance on designing for vibration and shock resistance.
Start by reviewing the datasheet and application notes to ensure proper usage and design. Check for proper PCB layout, thermal management, and soldering. If issues persist, contact Bourns' technical support for further assistance.
