Bourns provides a recommended PCB layout and land pattern in their application note AN204, which can be found on their website. It's essential to follow these guidelines to ensure optimal performance, low inductance, and minimal parasitic effects.
To select the correct current rating, consider the maximum current required by your circuit, taking into account any potential surge currents or inrush currents. Also, consider the operating temperature range and the desired level of reliability. Bourns provides a current rating selection guide in their datasheet, which can help with this process.
While the datasheet specifies an operating temperature range of -40°C to +125°C, it's essential to note that the inductor's performance may degrade at higher temperatures. For optimal performance, it's recommended to operate the inductor within a temperature range of -20°C to +100°C.
To minimize EMI, it's recommended to use a shielded inductor or add a shield around the inductor. Additionally, ensure that the PCB layout is designed to minimize radiation and that the inductor is placed away from sensitive components. Bourns provides EMI reduction techniques in their application note AN205.
To prevent damage, it's essential to store the inductors in a dry, cool place, away from direct sunlight and moisture. Avoid bending, flexing, or twisting the leads, and handle the components by the body, not the leads. Follow the ESD precautions outlined in the datasheet to prevent electrostatic discharge damage.
