Bourns provides a recommended PCB layout and land pattern in their application notes and design guides. It's essential to follow these guidelines to ensure optimal performance, low noise, and minimal electromagnetic interference (EMI).
To minimize magnetic field interference, keep the inductor at least 5 mm away from sensitive components, such as oscillators, antennas, or magnetometers. You can also use shielding materials or orient the inductor to minimize the magnetic field's impact.
Although the datasheet specifies a rated voltage of 10V, the maximum allowable voltage is typically 1.5 to 2 times the rated voltage. However, it's essential to consult with Bourns' application engineers or refer to their documentation for specific guidance on voltage derating and maximum allowable voltage.
The SRF is typically above the operating frequency range. To minimize the impact of SRF, ensure your operating frequency is below the SRF, and use impedance matching techniques to minimize reflections and resonances.
The inductor's thermal resistance (Rth) is specified in the datasheet. Ensure your design provides adequate thermal management, such as heat sinks or thermal vias, to keep the inductor's temperature within the recommended operating range.
