What makes Rubycon capacitors different from other brands?

Rubycon distinguishes itself through several key advantages developed over 70 years of capacitor manufacturing. Their proprietary electrolyte formulations provide extended operational life and excellent high-temperature performance. Rubycon's advanced sealing technology minimizes electrolyte evaporation, ensuring long-term reliability. The company's stringent quality control processes, including 100% testing of key parameters, result in consistently high-quality products. Rubycon offers one of the industry's broadest capacitance and voltage ranges, with specialized series for automotive, high-ripple, and long-life applications. Their global manufacturing footprint and vertical integration ensure supply stability and competitive pricing while maintaining Japanese quality standards.

How do I select the right Rubycon capacitor for my application?

Selecting the appropriate Rubycon capacitor requires evaluating several key parameters. First, determine the required capacitance value based on your circuit requirements. Next, select a voltage rating with appropriate derating - typically 20-30% above your maximum operating voltage. Consider the operating temperature range and select a series rated for your application's temperature extremes. For switching power supplies, calculate the ripple current requirements and select a capacitor with adequate ripple current rating and thermal characteristics. Lifetime requirements are critical - Rubycon offers standard, long-life, and ultra-long-life series. Physical constraints such as size, mounting type (radial, snap-in, screw terminal), and lead spacing must also be considered. Our FAE team can assist with detailed calculations and selection guidance.

What is the typical lifetime of Rubycon capacitors?

Rubycon capacitor lifetime varies by series and operating conditions. Standard series typically offer 2,000-5,000 hours at rated temperature (usually 85°C or 105°C). Long-life series such as the YXF and YXJ provide 10,000-12,000 hours at 105°C. Ultra-long-life series can achieve 15,000-20,000 hours at 105°C. Lifetime follows the Arrhenius equation - approximately doubling for every 10°C decrease in operating temperature. For example, a capacitor rated for 10,000 hours at 105°C can achieve 40,000 hours at 85°C and 160,000 hours at 65°C. Voltage derating also extends lifetime - operating at 80% of rated voltage typically doubles the expected life. Rubycon provides detailed lifetime calculation tools and application support.

Apply voltage derating and thermal management to maximize capacitor lifetime in your application.
