Development History and Corporate Vision

Rubycon's history dates back to 1952, when the company established a strategic focus on the research and manufacturing of capacitors. Over the past few decades, Rubycon has undergone several stages of development:

• Early Stage (1952-1970s): Rubycon initially focused on producing small aluminum electrolytic capacitors to meet the needs of the home appliance market. As market demand grew and technology advanced, the company gradually expanded its product line and began to venture into industrial applications.
• Expansion Phase (1980s-1990s): During this period, Rubycon increased its R&D investment and launched a variety of high-performance capacitor products, including low ESR (equivalent series resistance) aluminum electrolytic capacitors and high-temperature stable products. These innovations enabled Rubycon to quickly capture the high-end market.
• Globalization Phase (2000-Present): With the advancement of globalization, Rubycon actively expanded into overseas markets, establishing a sales network covering Asia, Europe, and North America. Simultaneously, the company continuously optimized its production processes, further improving product quality and cost-effectiveness.

Rubycon's corporate vision is to become a leading global capacitor supplier, providing customers with efficient and reliable solutions while prioritizing environmental protection and social responsibility. The company is ISO 9001 quality management system certified and ISO 14001 environmental management system certified, ensuring that all products meet international standards and are sustainable.

Core Product and Technological Advantages

Rubycon's core products mainly fall into two categories: aluminum electrolytic capacitors and plastic film capacitors. The following is a detailed introduction to these two product types and their technical characteristics:

Aluminum electrolytic capacitors

Aluminum electrolytic capacitors are among Rubycon's most representative products, widely used in power supply circuits, signal processing, and other electronic systems. These capacitors have the following key characteristics:

• High capacitance density: Rubycon's aluminum electrolytic capacitors use advanced anode foil processing technology to achieve higher capacitance values ​​within a limited space.
• Low ESR characteristics: The company's low ESR series capacitors can effectively reduce power loss in circuits and improve overall efficiency.
• Wide temperature range: Rubycon's aluminum electrolytic capacitors can operate stably in a temperature range of -55°C to +150°C, making them suitable for applications in extreme environments.
• Long life design: By optimizing the electrolyte formulation and sealing structure, Rubycon capacitors can last for thousands of hours or even longer.

Rubycon also offers a variety of package types to meet customer needs, including radial lead type, axial lead type and surface mount type (SMD) type, to meet the requirements of different application scenarios.

Plastic film capacitors

Plastic film capacitors are another core technology area for Rubycon, primarily used in high-frequency filtering, power factor correction (PFC), and motor starting. These capacitors are characterized by:

• Low loss: Plastic film capacitors have extremely low dielectric loss tangent (tanδ), making them suitable for high-frequency applications.
• High voltage withstand capability: Rubycon's film capacitors can withstand operating voltages of up to several kilovolts, making them suitable for high-voltage power conversion equipment.
• Excellent stability: These capacitors exhibit good parameter stability during long-term use and are not easily affected by temperature changes.
• Environmentally friendly materials: Rubycon uses RoHS-compliant environmentally friendly materials to ensure that the product's environmental impact is minimized throughout its entire life cycle.

In addition, Rubycon has developed specialized capacitors for specific applications, such as DC support capacitors for new energy vehicle drive systems and energy storage capacitors for photovoltaic inverters.

Technological innovation and R&D investment

Rubycon's success is inseparable from its strong emphasis on technological innovation. The company invests heavily in research and development, establishing a dedicated R&D center equipped with advanced experimental equipment and a team of experienced engineers. Below are some of Rubycon's key areas of technological innovation:

Materials Science

Improvements in capacitor performance largely depend on the application of new materials. Rubycon has conducted in-depth research in areas such as anolyte etching technology, electrolyte formulation, and thin film materials, achieving several breakthroughs. For example, the company has developed a novel solid electrolyte that significantly improves the frequency characteristics and reliability of capacitors.

Process improvement

To improve production efficiency and product quality, Rubycon continuously optimizes its manufacturing processes. The application of automated production lines not only reduces human error but also significantly shortens delivery cycles. Furthermore, the company has introduced a real-time monitoring system that enables the timely detection and resolution of potential problems during production.

Application Development

Rubycon is more than just a component supplier; it's a comprehensive solutions provider. The company works closely with its customers to deeply understand their specific needs, thereby developing the most suitable capacitor products. For example, in the new energy vehicle sector, Rubycon collaborates with several OEMs, providing them with customized capacitor solutions.

Market performance and global layout

Rubycon's products are widely recognized by customers worldwide for their superior performance and reliability. Currently, the company has established branches or agencies in many countries and regions, forming a strong sales and service network. Below are some of Rubycon's key achievements in the global market:

• Asian Market: As Rubycon's traditional strength, the Asian market accounts for a large share of the company's sales. Particularly in China, South Korea, and Southeast Asian countries, Rubycon's products are widely used in consumer electronics and industrial control.
• In the European and American markets, Rubycon has won the favor of many well-known companies with its high-end products and technical support. The company has established long-term partnerships with several multinational corporations to jointly promote technological innovation.
