The Complete Handbook of Inductors
Essential Knowledge for Engineers, Technicians, and Circuit Designers Who Specify, Install, and Maintain Inductive Components
by Alumigogo Books
non-fiction
Understand inductors from selection through troubleshooting—practical guidance for engineers and technicians who work with these critical passive components.
About this book
Inductors are fundamental passive components found in every switching power supply, RF filter, and energy storage circuit—yet many engineers and technicians lack a clear, practical understanding of how they work and how to choose the right one for the job.
This handbook cuts through the confusion. It explains what inductors actually do in a circuit, how their specifications translate to real-world performance, and how to select, install, and troubleshoot them correctly. Whether you are designing a DC-DC converter, filtering harmonic noise from a motor drive, suppressing EMI in a communications system, or debugging a circuit that is underperforming, you will find concrete examples, real failure modes, and practical decision criteria.
Written for professionals, businesses, and serious hobbyists who want to understand their components rather than guess, this reference covers inductor types and grades, how to read datasheets, how to avoid common installation mistakes, how to diagnose saturation and core loss, and what brands and suppliers actually deliver on their specifications. Whether you are in the field for thirty years or building your first switching circuit, this book is a resource you will return to.

★★★★★I've been a field technician for twelve years and grabbed this because I kept running into switching supplies with inductor problems I couldn't diagnose quickly. Chapter 1 alone clarified why core loss matters and how to spot saturation in the field—that's worth the price. The troubleshooting section is solid. Only minor gripe is it could use a few more circuit schematics in the selection chapter, but otherwise this is the reference I've been looking for.

★★★★★As someone who designs DC-DC converters, I found this handbook invaluable. It explains the practical side of inductor selection that datasheets and application notes dance around. The concrete examples in Chapter 1 (especially the switching supply discussion) immediately connected what I'd been doing intuitively to actual physics. Chapters 2 and 3 saved me hours on my last two designs by clarifying what specifications actually matter for my power levels. Highly recommended for anyone who builds circuits instead of just buying them.

★★★★★Good overview of inductors and the chapter on troubleshooting has some useful fault modes. That said, I found some of the later chapters (especially on business opportunities) felt a bit thin and didn't add much for me as an engineer. The first few chapters are genuinely helpful, but I expected more depth on advanced topics like core material trade-offs and high-frequency performance. Still a solid desk reference, just not the comprehensive deep-dive I was hoping for.
