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. You can also use shielding techniques, such as copper tape or mu-metal shielding, to contain the magnetic field.
Bourns recommends derating the voltage by 10-15% to ensure reliable operation. For the PWR163S-25-5R00FE, the maximum allowable voltage is 25V, so the derated voltage would be around 22-23V.
The PWR163S-25-5R00FE is rated for operation up to 125°C. However, it's essential to consider the inductor's temperature coefficient and potential degradation of performance at elevated temperatures. Consult with Bourns or a thermal management expert for specific guidance.
To select the correct inductor value, consider factors such as the operating frequency, current requirements, and desired inductance value. You can use Bourns' online inductor selection tools or consult with their application engineers for guidance.
