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 parasitic effects.
To handle the high current rating, ensure your PCB design includes a robust power distribution network, adequate copper thickness, and sufficient thermal management. You may also need to consider heat sinks or thermal interfaces to prevent overheating.
To minimize EMI and RFI, use proper shielding, grounding, and filtering techniques in your design. Bourns recommends following good electromagnetic compatibility (EMC) design practices, such as using a Faraday cage or shielding cans, and placing the inductor away from sensitive components.
While the SDR1105-220ML is rated for operation up to 125°C, it's essential to consider the derating curves and thermal management in your design. Ensure your system can maintain a safe operating temperature to prevent overheating and premature failure.
Choose an inductor value based on your application's specific requirements, such as current rating, frequency, and impedance. Consider the tolerance of the inductor, as it affects the overall performance and reliability of your design. Consult Bourns' application notes and technical support for guidance on selecting the optimal inductor value and tolerance.
