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 of 30 V, it's essential to derate the voltage based on the operating frequency, temperature, and other environmental factors to ensure reliable operation.
The SRF can affect the inductor's performance. To mitigate this, use a series resistor or capacitor to dampen the resonance, or choose an inductor with a higher SRF than your operating frequency.
Store the inductors in their original packaging, away from direct sunlight, moisture, and extreme temperatures. Handle the components by the body, not the leads, to prevent damage and electrostatic discharge.
