SRN4018BTA-220M Frequently Asked Questions (FAQs)
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 dedicated ground plane is also recommended.
To ensure reliability in high-temperature applications, it is recommended to derate the component's power rating according to the temperature derating curve provided in the datasheet. Additionally, ensure good thermal conductivity between the component and the PCB, and provide adequate airflow to dissipate heat.
Bourns recommends a soldering profile with a peak temperature of 260°C (500°F) for a maximum of 10 seconds, and a minimum temperature of 217°C (423°F) for a minimum of 90 seconds. The soldering process should be done in a nitrogen atmosphere to prevent oxidation.
Yes, the SRN4018BTA-220M is designed to withstand high-vibration environments. However, it is recommended to follow the recommended mounting and soldering procedures to ensure the component's reliability. Additionally, it is recommended to perform vibration testing according to the IEC 60068-2-6 standard to ensure the component's performance in the specific application.
To troubleshoot issues with the SRN4018BTA-220M, start by checking the component's input and output voltages, currents, and temperatures. Verify that the component is properly soldered and mounted, and that the PCB layout is correct. Check for any signs of physical damage or overheating. If the issue persists, contact Bourns' technical support for further assistance.
