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. The maximum allowable voltage is typically 2-3 times the rated voltage. Exceeding this may cause core saturation or even damage the inductor.
The self-resonant frequency (SRF) is typically not specified in the datasheet. To determine the SRF, use a network analyzer or impedance analyzer to measure the inductor's impedance vs. frequency. Then, design your circuit to avoid operating near the SRF to prevent unwanted resonances.
The tolerance on inductance value is typically ±5% or ±10%. This tolerance can affect the overall performance of your design, particularly in filter or resonant circuits. Be sure to consider the tolerance when designing your circuit and selecting components.
