Guangdong Haoer Electronics Co., Ltd. and Foshan Pin’er Electronics Co., Ltd.—sister enterprises operating under an integrated technical and management framework—are jointly dedicated to the research, development, manufacturing, and global distribution of high-frequency magnetic components and precision capacitors. Headquartered in the Guangdong–Hong Kong–Macao Greater Bay Area—the nation’s premier advanced manufacturing hub—the two companies deliver high-performance, high-reliability passive component solutions to the global power electronics industry.
Within this strategic technical alliance, Haoer Electronics specializes in high-frequency transformers, EMI filters, and custom inductor coils, while Pin’er Electronics focuses on film capacitors and industrial-grade capacitors. Pin’er operates its own certified production facility, manufacturing CBB series film capacitors, safety-certified X- and Y-class capacitors, and application-specific capacitors for induction cooking systems.
The group adheres to the core principles of “customer-centricity, technology leadership, and uncompromising quality.” As renewable energy systems, industrial power supplies, telecommunications infrastructure, and automotive electronics advance rapidly, the performance of passive components has become a critical determinant of end-product efficiency, power density, thermal management, and long-term reliability. In response, the group positions itself not merely as a component supplier, but as a trusted total technical solutions partner—collaborating with customers across the entire product lifecycle.
Technology-led collaboration: A seasoned R&D and applications engineering team—possessing deep domain expertise in high-frequency magnetics and advanced dielectric materials—supports customers from initial component selection and parametric optimization through electromagnetic simulation, thermal modeling, and topology-specific design validation. Custom solutions are offered for prevalent power architectures—including LLC resonant converters, phase-shifted full-bridge (PSFB), and other high-efficiency topologies—with rapid prototyping capabilities and agile time-to-sample delivery.
Rigorous quality assurance: A fully integrated quality management system—spanning incoming quality control (IQC), in-process inspection, and outgoing quality control (OQC)—ensures comprehensive electrical and environmental testing for every unit. Tests include inductance and coupling coefficient verification, dielectric withstand voltage, insulation resistance, dissipation factor (tan δ), capacitance stability under temperature and frequency variation, and accelerated life testing. All products comply with relevant national (e.g., GB/T) and international standards (e.g., IEC, UL, EN, AEC-Q200 where applicable).
End-to-end value delivery: The group provides seamless support across the customer journey—pre-sales technical consultation and value engineering analysis; real-time production visibility, robust scheduling discipline, and on-time-in-full (OTIF) delivery; and post-sales technical support, warranty administration, failure analysis, and lifecycle extension services. This holistic approach transforms transactional supply into enduring, outcome-oriented partnership.
Guangdong Haoer Electronics Broad application scope: Products serve mission-critical applications across switched-mode power supplies (SMPS), photovoltaic and energy storage inverters, electric vehicle onboard chargers (OBCs) and DC fast-charging infrastructure, 5G base station power systems, industrial automation and motor drives, and intelligent home appliances—enabling customers to achieve higher efficiency, miniaturization, thermal resilience, and intelligent system integration.
Guangdong Haoer and Foshan Pin’er will continue to intensify investment in next-generation R&D—including wide-bandgap-compatible magnetics, ultra-stable high-temperature capacitor materials, and AI-augmented design automation—as well as smart manufacturing upgrades aligned with Industry 4.0 principles. Committed to advancing sustainable electrification, the group seeks to deepen strategic partnerships with global OEMs, ODMs, and Tier-1 suppliers to accelerate innovation in green energy conversion and high-density power electronics.
