In the microscopic context of the electronic world, inductors, as the cornerstone of electronic components, play the role of the "heart", silently supporting the beating of signals and the flow of energy. With the booming development of emerging industries such as 5G communication and new energy vehicles, the demand for inductors in the market has surged, especially for integrated inductors that are gradually replacing traditional products due to their excellent performance. Chinese inductor companies have rapidly risen in this process, achieving breakthroughs in the high-end market and demonstrating significant development potential.
Inductors are basic electronic components that can convert electrical energy into magnetic energy and store it, also known as chokes, reactors, or inductive coils
It is one of the three essential passive electronic components in electronic circuits, and its working principle is based on the generation of alternating magnetic fields in and around wires when alternating current passes through them. The main functions of inductors include signal filtering, signal processing, and power management. According to different functions, inductors can be divided into high-frequency inductors (also known as RF inductors),
power inductors (mainly power inductors), and general circuit inductors. High frequency inductors are mainly used in coupling, resonance, and choke; The main uses of power inductors include changing voltage and choke current; And general circuits use inductors to provide a wide range and size of inductors, which are used for ordinary analog circuits such as sound and video, resonant circuits, etc.
According to different process structures, inductors can be divided into plug-in inductors and chip inductors. Chip inductors have the advantages of small size, light weight, high reliability, and easy installation, and have gradually replaced plug-in inductors as the mainstream. Chip inductors can also be divided into four categories: wound type, laminated type, thin film type, and braided type. Among them, winding type and laminated type are the most common. A modified version of the integrated inductor has been developed for winding type, which solves the problems of size standardization and coil leakage of traditional winding type. It has a smaller volume, larger current, and more stable temperature rise current, and its market share is rapidly increasing.
According to different materials, inductors can be divided into ceramic core inductors, ferrite inductors, and metal soft magnetic powder core inductors. Ferrite has the advantage of low loss, but can tolerate low saturation current and poor temperature stability, making it suitable for high-frequency and low-power working environments. The metal soft magnetic powder core is made of a mixture of ferromagnetic powder particles and insulating medium, which has high resistivity, low loss, and can withstand higher saturation current, making it suitable for relatively high-frequency and high-power working environments.
