Latest Inductor and Inductor Specifications I. Introduction Inductors are fundamental components in electronic circuits, playing a crucial role in energy storage, filtering, and signal processing. As passive components, they store energy in a magnetic field when electrical current flows through them. This article aims to provide a comprehensive overview of inductors, their specifications, the latest trends in inductor technology, and guidance on selecting the right inductor for various applications. II. Understanding Inductors A. Basic Principles of Inductance 1. Definition of Inductance Inductance is the property of an electrical conductor that opposes a change in current. It is measured in henries (H) and is defined as the ratio of the induced electromotive force (EMF) to the rate of change of current. When the current through an inductor changes, it generates a magnetic field that induces a voltage in the opposite direction, according to Lenz's Law. 2.

Lower DCR values are preferred as they result in reduced power losses and improved efficiency. D. Quality Factor (Q) The quality factor (Q) measures the efficiency of an inductor, defined as the ratio of its inductive reactance to its resistance at a specific frequency. A higher Q indicates lower energy losses and better performance. E. Self-Resonant Frequency (SRF) Self-resonant frequency is the frequency at which the inductor's reactance equals its resistance, causing it to behave like a resistor. It is crucial for high-frequency applications, as operating near or above this frequency can lead to performance degradation. F.
