With over a decade of deep industry expertise, we’ve firmly established core barriers in the inductor field.

Founded in 2007, Topsun has spent over a decade meticulously cultivating its expertise and has now grown into a full-chain inductor component service provider integrating R&D, manufacturing, and sales. It is a leading domestic supplier of monolithic power inductors. Based in the industrial hub of Bao'an, Shenzhen, the company closely follows trends in the electronic information industry, focusing on the R&D and manufacturing of high-end inductors. Based on its exceptional product quality and reliable delivery capabilities, it has successfully risen to the forefront of the industry.

As a key player in the semiconductor passive component sector, Topsun has deeply cultivated the high-end manufacturing field. Its products cover a wide range of applications—including AI servers, computers, intelligent driving, robotics, and network communications—precisely meeting the stringent demands of the next-generation information technology industry for high-end inductors. Thanks to its core advantages such as high current handling capability, stable electromagnetic characteristics, consistent temperature rise, low noise, and shock resistance, the company’s products have successfully entered top-tier international supply chains, breaking down overseas technological barriers in the high-end inductor segment and showcasing the robust strength of domestically produced passive components.

Technological innovation drives development, with continued intensification of R&D efforts and focused breakthroughs.

Innovation is the core driving force behind enterprise development. Topsun has consistently adhered to the development philosophy of “building the enterprise on technology and prioritizing quality,” continuously increasing its R&D investment and establishing a comprehensive, independently developed R&D system. The company has obtained numerous national invention patents and boasts industry-leading technological strength. Since 2025, the company has successively been granted multiple invention patents, including “A Preparation Method for Integrated Inductors with High Frequency Response Speed,” “A Formulation Design and Preparation Method for High Permeability Soft Magnetic Composite Powders,” and “A High-Voltage Molding Copper-Iron Co-Sintered Inductor and Its Preparation Method.” These patents represent key breakthroughs in material formulations, production processes, and product performance, further enhancing the company’s core competitiveness and enabling it to meet the high-end demands of emerging industries such as AI and computing power.

To align with the development trend of intelligent manufacturing, Topsun is actively promoting “intelligent transformation and digital upgrading.” We have introduced advanced MES systems to build a full-process digital production management system, enabling refined control and information-based collaboration across all production stages, thereby significantly enhancing production efficiency and product consistency. At the same time, the company continues to optimize its capacity layout by establishing branch offices such as the Kunshan subsidiary, thus creating a nationwide network for production, sales, and service. This enables us to provide customers with efficient, stable, and one-stop solutions, solidifying our leading position in the industry.

Upholding the original aspiration of craftsmanship to empower high-quality industrial development.

From tackling technological challenges to perfecting the industrial chain, Topsun has always remained true to its original commitment to manufacturing, focusing intently on its core business and cultivating it with meticulous care. We break through barriers through innovation and win the market with superior quality. Looking ahead, the company will continue to uphold the corporate spirit of "pursuing excellence and driving long-term success through innovation," seizing the opportunities presented by the development of the electronic information industry and the computing power economy. We will further strengthen technological innovation, optimize our industrial layout, and enhance our service capabilities, striving to become a globally leading provider of inductor component solutions and making solid contributions to the rise of China’s domestic semiconductor industry.
