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 rated voltage of 200V, the maximum allowable voltage is typically 1.5 to 2 times the rated voltage. However, it's essential to consult with Bourns' application engineers or refer to their voltage derating guidelines for specific use cases.
The SRF is typically above the operating frequency range. To avoid resonance issues, ensure your design's operating frequency is below the SRF. You can also use impedance analysis tools or consult with Bourns' application engineers for guidance.
The inductor's thermal resistance (Rth) is specified in the datasheet. Ensure your PCB design provides adequate thermal dissipation, such as using thermal vias, heat sinks, or thermal interface materials, to keep the inductor within its operating temperature range.
