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, thermal management, and reliability.
To minimize electromagnetic interference (EMI), keep the inductor at least 5 mm away from sensitive components, and consider using shielding or a mu-metal shield around the inductor. Additionally, orient the inductor to minimize the magnetic field's impact on nearby components.
While the datasheet specifies a maximum voltage rating, it's essential to derate the voltage based on the application's requirements. A general rule of thumb is to derate the voltage by 10-20% to ensure reliable operation and prevent premature failure.
The SRF is typically not a concern in most applications, but if you're operating near the SRF, it's essential to ensure the inductor is not resonating. You can use impedance analysis tools or consult with Bourns' application engineers to determine the best approach for your specific design.
The PWR163S-25-20R0J has a maximum operating temperature of 125°C. Ensure good airflow around the inductor, and consider using thermal interfaces or heat sinks if the inductor is expected to operate at high temperatures or with high current densities.
