The recommended land pattern for the SER2014-402MLD is a rectangular pad with a size of 2.5 mm x 1.5 mm, with a non-solder mask defined (NSMD) pad shape.
The SER2014-402MLD has a maximum operating temperature of 125°C. Ensure good airflow around the inductor, and consider using a thermal interface material (TIM) to improve heat transfer between the inductor and the PCB.
The SRF of the SER2014-402MLD is not explicitly stated in the datasheet, but it can be estimated using the inductor's inductance and capacitance values. A rough estimate is around 100-150 MHz.
While the SER2014-402MLD is suitable for high-frequency applications, its performance may degrade above 50 MHz due to the inductor's internal capacitance and resistance. Consider using a more specialized high-frequency inductor for applications above 100 MHz.
To ensure reliability, follow proper PCB design and assembly guidelines, including using a robust soldering process, avoiding excessive mechanical stress, and implementing adequate thermal management. Additionally, consider using a more reliable inductor with a higher temperature rating and better moisture resistance.
