Bourns provides a recommended PCB layout and land pattern in their application notes. It's essential to follow these guidelines to ensure optimal performance, low inductance, and minimal signal degradation.
To minimize magnetic field interference, keep the inductor at least 5 mm away from sensitive components, such as oscillators, antennas, or magnetometers. You can also use shielding materials or orient the inductor to minimize the magnetic field's impact.
Bourns recommends derating the voltage by 10-15% to ensure reliable operation. For the PEL12D-4225S-S2024, the maximum allowable voltage is approximately 85% of the rated voltage (2.5V).
The PEL12D-4225S-S2024 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 Bourns' application notes for guidance on high-temperature operation.
To minimize EMI and RFI emissions, use proper PCB layout techniques, such as grounding the inductor's shield (if applicable), using a common-mode choke, and implementing EMI filters or shielding. Consult Bourns' application notes and relevant industry standards for guidance.
