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, to contain the magnetic field.
Bourns recommends derating the voltage by 10-20% to ensure reliable operation and prevent overheating. For the PWR263S-35-R500F, the maximum allowed voltage is 35V, so a safe operating voltage would be around 28-31V.
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-R500F has a maximum operating temperature of 125°C. Ensure good airflow around the inductor, and consider using thermal interfaces or heat sinks to dissipate heat. You can also use thermal simulation tools to optimize your design.
