Industry Overview
Inductors are electronic components that operate based on the principle of electromagnetic induction. Power inductors, as passive electronic components, are primarily designed to store energy in the form of a magnetic field when current flows through them. Power inductors are widely used in various power supply circuits, playing a key role in energy storage and conversion, as well as stabilizing current and voltage. They ensure the stable operation and electromagnetic compatibility of electronic device circuits by smoothing fluctuating currents (filtering) and suppressing interference signals (anti-interference).
Industry Development Background
As inductive components specifically used in power management circuits, the core task of power inductors is to handle energy rather than signals. They are mostly used in power conversion and high-current circuits, emphasizing high current tolerance, low loss, saturation resistance, and high heat dissipation. In 2024, the sales revenue of inductor devices in China was approximately 38 billion RMB.
Industry Chain Structure
Looking at the industry chain, the upstream consists of raw materials and equipment supply, involving magnetic materials (ferrite powder, magnetic cores, etc.), conductive materials (copper materials, silver paste, etc.), packaging auxiliary materials (glue, insulating films, etc.), and production equipment (winding machines, molding equipment, etc.). The midstream involves design and manufacturing, covering processes such as inductor winding, magnetic core assembly, molding, and testing. The downstream is the application segment, including but not limited to consumer electronics, automotive electronics, communications, computing power, industrial, and new energy sectors.

Market Development Status
On the one hand, as core passive components for power conversion and power management, power inductors continue to evolve in tandem with the high-frequency transition of electronic circuits, the increase in power density, and the iteration of power architectures. On the other hand, the electrification of New Energy Vehicles (NEVs), the construction of AI (Artificial Intelligence) and computing power infrastructure, and the upgrading of photovoltaic and energy storage systems jointly drive the demand for high-reliability, high-current, and high-frequency inductors. In terms of sales revenue, the global power inductor market size was approximately 32.4 billion RMB in 2024.
Key Enterprises
Shenzhen Sunlord Electronics Co., Ltd., founded in 2000, is a high-tech enterprise specializing in the R&D, production, and sales of various chip electronic components. The main products of Sunlord Electronics include four major categories: magnetic devices, microwave devices, sensitive devices, and precision ceramics, which are widely used in communications, consumer electronics, computers, automotive electronics, new energy, network communications, and industrial electronics. In the field of power inductors, Sunlord possesses the most comprehensive product categories and industry-leading design and manufacturing platforms in the industry, involving multilayer platform power inductors, coated platform power inductors, assembled platform power inductors, and molded platform power inductors. In 2025, the total operating revenue of Sunlord Electronics was 6.745 billion RMB.
Industry Development Trends
In the future, metal composite magnetic materials with higher saturation characteristics may accelerate the substitution of traditional ferrite materials to adapt to high-frequency and high-current working environments. Meanwhile, the integrated molding process is expected to gradually develop into the mainstream technical route in the power inductor industry, thanks to its low loss and strong electromagnetic interference resistance. At the same time, the application of flat wire winding technology is becoming more common, which is expected to effectively reduce DC resistance, thereby improving the efficiency and current-carrying capacity of power electrical products.
