Bourns provides a recommended PCB layout and land pattern in their application notes. It's essential to follow these guidelines to ensure proper thermal management, minimize parasitic inductance, and optimize performance.
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.
While the datasheet specifies a maximum rated current, it's essential to consider the voltage across the inductor as well. As a general rule, keep the voltage across the inductor below 1.5 times the maximum rated voltage to prevent saturation and ensure reliable operation.
The SRF is typically not a concern in most applications. However, if you're operating near the SRF, ensure your design includes proper damping mechanisms, such as resistors or capacitors, to prevent oscillations and ensure stability.
The 3590S-2-103L has a maximum operating temperature of 125°C. Ensure good airflow, use thermal interfaces or heat sinks if necessary, and follow proper PCB design guidelines to minimize thermal resistance and ensure reliable operation.
