Development History and Corporate Vision

Rubycon's history can be traced back to 1952, when the company was founded and established a strategic direction to focus on the research and development and manufacturing of capacitors. Over the past few decades, Rubycon has gone through several stages of development:

• Initial stage (1952-1970s): Rubycon initially focused on the production of 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 enter 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 occupy the high-end market.
• Globalization stage (2000 to present): With the advancement of globalization, Rubycon actively expanded overseas markets and established a sales network covering Asia, Europe and North America. At the same time, the company continued to optimize production processes to further improve 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 focusing on environmental protection and social responsibility. The company has obtained ISO 9001 quality management system certification and ISO 14001 environmental management system certification to ensure that all products meet international standards and are sustainable.

Core product and technology advantages

Rubycon's core products mainly include aluminum electrolytic capacitors and plastic film capacitors. The following is a detailed introduction to these two types of products and their technical features:

Aluminum electrolytic capacitors

Aluminum electrolytic capacitors are one of Rubycon's most representative products and are widely used in power circuits, signal processing and other electronic systems. This type of capacitor has the following significant features:

• 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 low ESR series capacitors launched by the company can effectively reduce power loss in the circuit and improve overall efficiency.
• Wide Temperature Range: Rubycon's aluminum electrolytic capacitors can operate stably in the temperature range of -55°C to +150°C, suitable for applications in extreme environments.
• Long life design: Through the optimization of electrolyte formula and sealing structure, the service life of Rubycon capacitors can reach thousands of hours or even longer.

Rubycon also provides a variety of packaging forms according to customer needs, including radial pin type, axial pin type and surface mount type (SMD) to meet the requirements of different application scenarios.

Plastic film capacitors

Plastic film capacitors are another core technology area of ​​Rubycon, mainly used in high-frequency filtering, power factor correction (PFC) and motor starting. The characteristics of this type of capacitor include:

• Low loss: Plastic film capacitors have extremely low dielectric loss tangent (tanδ), suitable for high-frequency applications.
• High withstand voltage capability: Rubycon's film capacitors can withstand working voltages up to several thousand volts and are 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 environmentally friendly materials that comply with the RoHS directive to ensure that the impact of the product on the environment is minimized throughout its 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 high attention to technological innovation. The company has invested a lot of resources in R&D and established a dedicated R&D center equipped with advanced experimental equipment and an experienced team of engineers. The following are several key areas of Rubycon's technological innovation:

Materials Science

The improvement of capacitor performance depends largely on the application of new materials. Rubycon has conducted in-depth research in anode foil corrosion technology, electrolyte formulation and thin film materials, and has achieved a number of breakthrough results. For example, the company has developed a new solid electrolyte that significantly improves the frequency characteristics and reliability of capacitors.

Process Improvement

In order to improve production efficiency and product quality, Rubycon continuously optimizes the manufacturing process. The application of automated production lines not only reduces human errors, but also significantly shortens the delivery cycle. In addition, the company has introduced a real-time monitoring system that can promptly detect and solve potential problems in the production process.

Application Development

Rubycon is not only a component supplier, but also a comprehensive solution provider. The company works closely with customers to deeply understand their specific needs and develop the most suitable capacitor products. For example, in the field of new energy vehicles, Rubycon cooperates with many vehicle manufacturers and provides them with customized capacitor solutions.

Market performance and global layout

Rubycon's products are widely recognized by customers around the world for their excellent performance and reliability. At present, the company has established branches or agencies in many countries and regions, forming a strong sales and service network. The following are some important performances of Rubycon in the global market:
