Comparing Nichicon and Rubycon Capacitors: Which One to Choose?

When it comes to selecting capacitors for electronic circuits, two popular brands stand out: Nichicon and Rubycon. Both brands offer high-quality capacitors that cater to different needs and applications. In this article, we'll delve into the world of Nichicon and Rubycon capacitors, highlighting their differences, similarities, and which one to choose for your specific requirements.

Overview of Nichicon Capacitors

Nichicon is a well-established Japanese company known for its extensive range of capacitors, including film, ceramic, and electrolytic types. With a strong focus on research and development, Nichicon continuously improves its products to meet the evolving demands of the electronics industry.

Overview of Rubycon Capacitors

Rubycon is another Japanese company that specializes in the manufacture of capacitors, particularly electrolytic and film types. Founded in 1952, Rubycon has built a reputation for delivering high-reliability capacitors that meet the stringent requirements of various industries, including automotive, industrial, and consumer electronics.

Key Differences

Quality and Reliability

Both Nichicon and Rubycon are known for their high-quality products, but Nichicon is often considered to have a slight edge in terms of reliability and durability. Nichicon's capacitors are built with rigorous quality control measures, ensuring that they can withstand harsh operating conditions.

Capacitance Range

Rubycon offers a wider range of capacitance values, making them a popular choice for applications that require specific capacitance values. Nichicon, on the other hand, focuses on providing a more limited range of capacitance values, but with a greater emphasis on precision and accuracy.

Temperature Rating

Nichicon capacitors are known for their high-temperature rating, making them suitable for applications that require operation in extreme temperatures. Rubycon capacitors, while still reliable, have a slightly lower temperature rating.


Rubycon capacitors are generally more affordable than Nichicon capacitors, making them an attractive option for budget-conscious projects.


Compliance with Industry Standards

Both Nichicon and Rubycon capacitors meet or exceed industry standards, such as RoHS and REACH compliance, ensuring that they are environmentally friendly and safe for use in various applications.

Wide Range of Applications

Both brands offer capacitors suitable for a wide range of applications, including power supplies, audio equipment, automotive systems, and more.

Choosing the Right Capacitor

So, which capacitor brand should you choose? Here are some general guidelines:

If You Need High-Reliability and Precision:

Choose Nichicon capacitors for applications that require high-reliability, low-ESR, and precise capacitance values.

If You Need a Wide Range of Capacitance Values:

Select Rubycon capacitors for applications that require a specific capacitance value not offered by Nichicon.

If You're on a Budget:

Consider Rubycon capacitors for cost-sensitive projects that still require reliable performance.


In conclusion, both Nichicon and Rubycon capacitors are high-quality options for your electronic projects. While Nichicon is known for its reliability and precision, Rubycon offers a wider range of capacitance values and a more affordable price point. By considering your specific requirements and choosing the right capacitor brand, you can ensure that your project meets its performance and reliability goals.
