Nantong HUAYU Electronics Co., Ltd.
Established in 1987 as Nantong HUAYU Capacitor Factory in Zhangzhishan Town, Tongzhou District, Nantong, Jiangsu Province, China, our company has grown from a small workshop into a professional manufacturer specializing in large-format aluminum electrolytic capacitors.
For over three decades, we have focused exclusively on snap-in terminal and screw terminal aluminum electrolytic capacitors. This unwavering specialization has allowed us to develop deep expertise in capacitor design, raw material selection, manufacturing processes, and quality control.
Today, HUAYU capacitors are trusted by manufacturers of frequency inverters, welding equipment, UPS systems, power supplies, and industrial automation equipment across more than 50 countries worldwide.
Our History
The Beginning — Founded in Nantong, China
Company founded as Nantong HUAYU Capacitor Factory, beginning production of aluminum electrolytic capacitors in Zhangzhishan Town, Tongzhou District, Nantong, Jiangsu Province.
Expansion & Quality System
Expanded product lines to include screw terminal capacitors. Established formal quality management systems and began serving domestic industrial equipment manufacturers.
Going Global
Developed snap-in terminal capacitor series for frequency inverter applications. Started international export operations, gained CE certification, and began establishing relationships with overseas customers.
Innovation & Market Expansion
Launched multiple new series (CD293–CD298) targeting high-ripple-current and extended-life applications. Significant expansion of export markets to Europe, Southeast Asia, the Middle East, and the Americas.
Trusted by Manufacturers Worldwide
Operating with 17 product series, serving 500+ customers in 50+ countries. Continuing to invest in R&D for next-generation capacitor technology while maintaining our core strength in custom specification manufacturing.
Our Core Strength: Custom Specifications
While many capacitor manufacturers focus on standard products, HUAYU's true competitive advantage lies in our ability to produce capacitors to your exact specifications.
Custom Capacitance & Voltage
Need a non-standard capacitance value or voltage rating? We can adjust formulations and winding parameters to meet your specific electrical requirements.
Custom Case Dimensions
From diameter to height, we can produce capacitors in case sizes that fit your exact PCB layout or enclosure constraints.
Application-Optimized Design
Tell us your application conditions and we will design a capacitor optimized for those specific conditions.
Extended Life Options
We offer extended life versions with enhanced electrolyte formulations and sealing technologies.
Temperature Ratings
Standard 85°C and 105°C rated products. For extreme environments, we can develop capacitors with special electrolyte systems.
Engineering Partnership
We don't just sell capacitors — we partner with your engineering team throughout the design and qualification process.
Quality Assurance
Quality is the foundation of everything we do at HUAYU. Every capacitor that leaves our factory has passed through our comprehensive quality control system:
- Raw Material Inspection: All incoming materials are tested against strict specifications before entering production.
- In-Process Control: Automated monitoring at every critical production stage.
- Aging & Screening: All finished capacitors undergo accelerated aging to screen out early failures.
- Final Testing: 100% testing of capacitance, ESR, leakage current, and impedance.
- Traceability: Full batch traceability from raw materials through production to final shipment.
Application Fields
HUAYU capacitors are engineered for the most demanding industrial applications where reliability cannot be compromised:
