Hongyi Electronics: An Innovative Leader in New Energy Capacitor Field

In the wave of vigorous development of the new energy industry, Hongyi Electronics has become a leader in the industry with its outstanding performance in the R&D, manufacturing, and production of film capacitors. Since its establishment in 2000, Hongyi Electronics has always focused on the field of film capacitors, deepening its cultivation with firm determination and unremitting efforts.

, Focus on R&D, Driven by Technological Innovation

Hongyi Electronics attaches great importance to R&D investment. For nearly a decade, annual R&D investment has accounted for nearly 4% of sales revenue, a ratio that leads the industry. In 2015, the company boldly transformed its production R&D model from "copy-based R&D" to "original R&D", fully investing in original innovative R&D.

Technological innovation has achieved remarkable results. In the field of metallized film capacitors, the company′s independently developed "self-healing technology" is unique, which can automatically repair the capacitor when a short circuit occurs, with technology leading the industry by more than one generation. At present, Hongyi Electronics has more than 30 patent layouts, and technical personnel account for more than 30% of the total. The strong R&D team has become a powerful support for technological innovation. These patents cover multiple key links from material innovation to production process optimization, laying a solid foundation for the continuous upgrading of the company′s products.

Facing the harsh requirements of film capacitors in the new energy vehicle field, such as withstanding extreme temperatures (-40° C to 125° C), high voltage (above 1000V), and other harsh environments, Hongyi Electronics has not only enabled its products to easily meet these challenges through continuous R&D and improvement but also maintained a yield rate of over 99% all year round. The developed film capacitors adopt the "double-sided metallization + end-face welding" process, which increases the current carrying capacity to more than 1500A, successfully meeting the requirements of the 800V high-voltage platform and injecting strong impetus into the development of the new energy vehicle industry.

, Quality First, Strictly Controlling Production Processes

- Specialized Solutions: Industrial capacitors for frequency converters, photovoltaic capacitors with anti-harmonic design, and DC link capacitors tested for 10, 000+ hours of high-temperature operation. Each product undergoes 58 quality checks to ensure performance from -40º C to +125º C.

R&D & Quality Control

Our R&D lab features advanced equipment like Zwick testers and Keysight analyzers, simulating 20+ harsh conditions. With 15% annual R&D investment, we hold 27 patents, including the innovative "edge gold spraying process" improving self-healing by 30%. A "double-blind testing + big data traceability" system maintains a defect rate <0.03%.

Future Vision

Focused on new energy, we develop capacitors for EV powertrains and energy storage, aiming to reduce product size by 40% via ultra-thin metallized film tech. Our "capacitor + intelligent monitoring" solutions enable real-time equipment health tracking. Committed to sustainability, we adopt lead-free processes and recyclable materials, cutting carbon emissions by 500+ tons annually. Driven by the vision of "thriving enterprise, happy employees, satisfied customers", we lead in smart capacitor manufacturing for global energy efficiency and green development.
