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 EMI, and high reliability.
To minimize magnetic field interference, keep the inductor at least 5 mm away from sensitive components, and orient the inductor to minimize the magnetic field's impact. You can also use shielding or mu-metal to contain the magnetic field.
The SRN8040TA-331M is rated for operation from -40°C to +125°C. However, derating may be necessary for high-temperature applications. Consult the datasheet and Bourns' application notes for more information.
The SRN8040TA-331M is designed to withstand moderate vibration and shock. However, for extreme environments, consider using a more ruggedized inductor or adding additional mechanical support to ensure reliability.
To minimize EMI and RFI emissions, use proper PCB layout techniques, such as separating the inductor from sensitive components, using ground planes, and adding EMI filters or shielding as needed.
