Coilcraft provides a recommended PCB land pattern in their documentation, which includes a rectangular pad with a size of 3.8 mm x 2.5 mm and a thermal relief pattern to ensure good thermal dissipation.
To handle the high current rating of the CS1750L, ensure that your PCB design includes a sufficient copper thickness and width to handle the current, and consider using multiple vias to connect the inductor to the power plane. Additionally, ensure that your thermal design can dissipate the heat generated by the inductor.
Coilcraft provides a derating curve in their documentation, which shows the maximum current rating of the inductor at different ambient temperatures. The derating curve is typically provided in the datasheet or in a separate application note.
To select the correct inductance value, consider the specific requirements of your application, including the operating frequency, current rating, and desired impedance. Coilcraft provides a range of inductance values for the CS1750L, and you can use their online tools or consult with their application engineers to select the optimal value for your design.
The self-resonant frequency of the CS1750L is typically not specified in the datasheet, but it can be estimated using the inductor's inductance value and the parasitic capacitance of the component. Coilcraft's application engineers can provide guidance on estimating the self-resonant frequency for your specific application.
