Bourns provides a recommended PCB layout and land pattern in their application notes. It's essential to follow these guidelines to ensure proper thermal management, minimize parasitic inductance, and optimize performance.
To avoid damage, follow the recommended soldering profile, and ensure the inductor is properly aligned on the PCB. Use a solder paste with a high melting point, and avoid excessive soldering temperatures or prolonged exposure to heat.
While the datasheet specifies a maximum voltage rating, it's essential to derate the voltage based on the application's operating conditions. As a general rule, derate the voltage by 10-20% to ensure reliable operation and prevent premature failure.
The SRF is typically not specified in the datasheet, but it can be estimated using the inductor's inductance and capacitance values. You can also use simulation tools or consult with Bourns' application engineers to determine the SRF and its impact on your design.
The inductor's thermal resistance (Rth) is specified in the datasheet. Ensure proper heat dissipation by providing adequate airflow, using thermal interfaces or heat sinks, and following proper PCB design guidelines for thermal management.
