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.
While the datasheet specifies a maximum rated voltage, it's essential to consider the voltage stress during switching, surge, and fault conditions. As a general rule, keep the voltage stress below 1.5 times the rated voltage to ensure reliability and prevent premature failure.
When selecting an inductor, consider factors such as operating frequency, current rating, inductance value, and physical size. Consult Bourns' selection guides and application notes to ensure the SRU5028-100Y meets your application's requirements.
The SRU5028-100Y has a maximum operating temperature of 125°C. Ensure proper heat dissipation by providing adequate airflow, using thermal interfaces or heat sinks, and keeping the inductor away from heat sources.
