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 thermal resistance, and minimal electromagnetic interference (EMI).
To minimize electromagnetic interference (EMI), keep the inductor at least 5 mm away from sensitive components, such as oscillators, antennas, or other inductors. You can also use shielding techniques, like copper tape or mu-metal shielding, to contain the magnetic field.
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 use online calculators or consult with Bourns' application engineers to determine the SRF and its potential impact on your design.
The PWR263S-35-50R0F has a maximum operating temperature of 125°C. Ensure good airflow around the inductor, and consider using thermal interfaces or heat sinks to maintain a safe operating temperature. You can also use thermal simulation tools to model the inductor's thermal performance.
