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 assembly and to minimize parasitic inductance.
To select the correct inductor, consider factors such as operating frequency, current rating, inductance value, and DC resistance. Bourns offers a product selection guide and online tools to help engineers choose the right inductor for their application.
The SRF of the SRN2010TA-R47Y is not explicitly stated in the datasheet, but it can be estimated using the inductance and capacitance values. The SRF is typically above the operating frequency range, but it's essential to consider it in high-frequency designs to avoid unwanted resonances.
The SRN2010TA-R47Y has a rated operating temperature range of -40°C to +125°C. While it can tolerate high temperatures, it's essential to consider the derating curves and temperature coefficients to ensure reliable operation in extreme environments.
To minimize EMI issues, use proper shielding, keep the inductor away from sensitive components, and consider using a shielded inductor or a common-mode choke. Bourns also provides guidance on magnetic field reduction in their application notes.
