About Haoer Electronics - China Professional Manufacturer of High-frequency Transformer and Magnetic Components

Our History

A Legacy of Excellence in Electronic Components

Guangdong Haoer Electronics Co., LTD and Foshan Pin'er Electronics Co., Ltd. are sister enterprises under the same technical and management system. They focus on the research, development, manufacturing and sales of high-frequency transformers and capacitors. We are based in the core area of China's manufacturing industry - the Guangdong-Hong Kong-Macao Greater Bay Area. We are committed to providing high-performance and highly reliable core magnetic components and capacitor solutions for the global power electronics industry.

Gooder Electronics specializes in the research, development and manufacturing of high-frequency transformers, filters and inductor coils. While Piller Electronics focuses on thin-film capacitors and industrial capacitors, it has its own factory and mainly produces products such as the CBB series, safety standards compliant capacitors and special capacitors for induction cookers.

Since our establishment, we have always adhered to the core values of "putting customers at the center, taking technology as the foundation, and seeking survival through quality" . We are well aware that in the rapidly developing fields of new energy, industrial power supplies, communication equipment, and automotive electronics, the performance of core components directly determines the efficiency, power density and reliability of the end products. Therefore, we are not merely a component manufacturer; we also aspire to become a "comprehensive technology solution partner" that customers can trust.

Technology-driven and deeply collaborative

We have an experienced R&D and engineering team that is proficient in high-frequency magnetism and the application of dielectric materials. From product selection, parameter optimization to simulation support, we can deeply participate in the circuit design stage of our customers, providing customized solutions for various topologies such as LLC and PSFB, and responding quickly to prototype sample requirements.

Quality first, fully controllable

We have established a comprehensive quality control system from IQC (incoming inspection) to OQC (outgoing inspection). Each transformer and capacitor undergoes strict electrical performance tests (such as sensitivity, withstand voltage, insulation, loss, etc.) to ensure the consistency and stability of the factory products and comply with domestic and international safety standards.

Full-chain service, win-win cooperation

We have constructed a complete service system covering "pre-sales - in-process sales - post-sales". Pre-sales provide professional consultation and value engineering analysis; in-process sales ensure transparent production and efficient delivery; post-sales offer rapid technical response, quality assurance, and long-term product lifecycle management. What we sell is not just products, but a reliable commitment and a lasting partnership.

Focus on specific fields, wide application

Our products are widely used in switching power supplies, photovoltaic/storage inverters, vehicle-mounted power supplies and charging facilities for new energy vehicles, communication base station power supplies, industrial control and other cutting-edge fields, helping customers address industry challenges of efficiency, miniaturization and intelligence.

Looking to the future, Guangdong Haoer and Foshan Pin'er will continue to deeply focus on high-frequency magnetic components and capacitors technology, and will continue to invest in research and development as well as the upgrading of intelligent manufacturing. We look forward to working together with global customers and partners in the wave of power electronics technology, moving forward side by side, and jointly promoting the development of green energy and efficient power conversion businesses.

Choose us and you will obtain a stable, professional and responsible core component partner, allowing you to focus more on the core innovation of your own system.
