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 voltage of 50 V, the inductor can withstand voltage stress up to 1.5 times the rated voltage for short durations. However, it's essential to derate the voltage according to the operating frequency and temperature to ensure reliability.
The SRF is typically not specified in the datasheet, but you can estimate it using the inductor's inductance and capacitance values. The SRF can affect the inductor's impedance and Q factor, so it's essential to consider it when designing filters or impedance-matching networks.
The inductor's thermal resistance (Rth) is specified in the datasheet. Ensure good thermal conductivity by using a thermally conductive PCB material, and consider adding thermal vias or heat sinks to dissipate heat efficiently.
