Bourns provides a recommended PCB layout and land pattern in their application note AN164, which can be found on their website. It's essential to follow these guidelines to ensure optimal performance and minimize parasitic effects.
The inductor's thermal derating is critical to ensure reliable operation. Bourns provides thermal derating curves in the datasheet. Engineers should consider the maximum operating temperature, ambient temperature, and the inductor's power rating to determine the derating factor. Additionally, proper PCB design, thermal vias, and heat sinks can help mitigate thermal issues.
The SRF is not explicitly stated in the datasheet, but it can be estimated using the inductor's inductance and capacitance values. The SRF typically occurs at a frequency where the inductor's impedance peaks. Engineers should ensure that the operating frequency is below the SRF to avoid unwanted resonances and losses.
Bourns offers a range of inductors with different core materials, shielding options, and saturation currents. Engineers should consider their specific application requirements, such as operating frequency, current, and voltage, to select the most suitable inductor. Bourns' application notes and selection guides can provide valuable insights to aid in the selection process.
Bourns recommends following standard ESD handling procedures, storing the inductors in their original packaging, and avoiding mechanical stress, moisture, and extreme temperatures. Engineers should also follow proper soldering and assembly techniques to prevent damage during the manufacturing process.
