Electronic circuit noise and point-of-load power conversion are important topics in today’s advanced electronics landscape. At the heart of solutions that combat these problems is the timeless fixed inductor. Single stage buck converters rely heavily on inductors to store and transfer energy in power supplies as well as filtering noise or blocking high frequencies while passing DC current in choke circuits.

Among the design considerations are the inductor’s self-resonant frequency, component ratings, test frequency and other features such as material makeup and core type/material, inductance value, tolerance, inductance and self-resonant frequency, current rating, and shielding.

Whether you are an engineer, student, or maker this academic component reference guide will aid in the decision making in determining which type, style, or configuration of fixed inductor is best for your application.
