Guangdong Haoer Electronics Co., Ltd. and Foshan Pin'er Electronics Co., Ltd. are sister enterprises operating under an integrated technical and management framework, strategically located in the Guangdong-Hong Kong-Macao Greater Bay Area, the core of China's manufacturing industry. Together, we are dedicated to the research, development, manufacturing, and sales of high-frequency transformers and capacitors, providing high-performance, highly reliable magnetic components and capacitor solutions for the global power electronics sector.
Our dual specialization ensures comprehensive coverage of critical component needs. Haoer Electronics concentrates on high-frequency transformers, filters, and inductor coils, while Pin'er Electronics runs its own factory focused on thin-film capacitors and industrial capacitors, producing CBB series, safety-standard compliant capacitors, and special capacitors for induction cookers. This complementary structure allows us to offer a one-stop resource for diverse power conversion applications.
Since our inception, we have adhered unwaveringly to the core values of customer centricity, technology as our foundation, and quality as our guarantee of survival. We recognize that in fast-evolving fields such as new energy, industrial power supplies, communication equipment, and automotive electronics, the performance of core components directly dictates the efficiency, power density, and reliability of end products. Therefore, we position ourselves not merely as a component manufacturer, but as a comprehensive technology solution partner that customers can trust.
Our experienced R&D and engineering team excels in high-frequency magnetics and dielectric material applications. From product selection and parameter optimization to simulation support, we actively engage in our customers' circuit design stages, offering customized solutions for various topologies including LLC and PSFB, and we respond swiftly to prototype sample requests. At the same time, we have established a rigorous quality control system that covers every step from incoming inspection to outgoing inspection. Each transformer and capacitor undergoes strict electrical performance tests—such as inductance, withstand voltage, insulation, and loss measurements—to ensure consistency, stability, and full compliance with international safety standards.
Beyond products, we have built a complete service chain covering pre-sales, in-process, and after-sales support. Pre-sales activities include professional consultation and value engineering analysis; during the sales phase, we ensure transparent production scheduling and on-time delivery; and post-sales, we provide rapid technical responses, quality assurance, and long-term product lifecycle management. What we deliver is not just a component, but a reliable commitment and a lasting partnership.
Our products are widely applied in switching power supplies, photovoltaic and storage inverters, on-board power supplies and charging facilities for new energy vehicles, telecom base-station power supplies, and industrial controls—helping customers address the industry's pressing challenges of efficiency, miniaturization, and intelligence. Looking ahead, Guangdong Haoer and Foshan Pin'er will continue to deepen our focus on high-frequency magnetic components and capacitor technology, with sustained investment in R&D and smart manufacturing upgrades. We eagerly look forward to working with global customers and partners, advancing side by side in the wave of power electronics technology, and jointly promoting the development of green energy and efficient power conversion. Choose us, and you will gain a stable, professional, and responsible core component partner, allowing you to concentrate on the core innovation of your own systems.
