English Name: Rubycon
Manufacturer: Japan RUBYCON CORPORATION. This is a professional company with over 40 years of experience in producing aluminum electrolytic capacitors. Known for its strict production management and high-quality products, RUBYCON develops and produces the main raw materials—aluminum foil and electrolyte—internally, ensuring consistent quality across all its capacitors. As a well-known international brand, RUBYCON capacitors are widely used in energy-saving lamps, ballasts, electric meters, switching power supplies, and more.



Main Series of Capacitors: - SMD Electrolytic: SEV (40~85°C), SGV (2000 hours) (-40~105°C) - Special Meter Series: YXA, YXF (High Frequency Long Life) (-55~105°C) - Energy-Saving Lamp Series: YXA, BXA (1000~12000 hours), BXC (5000~1000 hours), CFX (5000 hours) (-55~105°C) - Switching Power Supply Dedicated Series: YXA, YXF, YXG, MXR, MXG, MXC, AXW, WXA, ZL, ZLH (-40~85°C) - Standard Series: YK, USR (-40~85°C)

In the fields of personal computers and audio equipment, components using Rubycon capacitors are highly regarded for their reliability and performance.

How to Distinguish Real from Fake Rubycon Capacitors: 1. **Appearance**: Genuine Rubycon capacitors have a smooth, dark surface with strong reflectivity under sunlight. The anti-storm shading has a "K" mark, and the one on the left is authentic. 2. **Product Markings**: The genuine product is clearly marked as "Rubycon," while counterfeits may show "Rukycon" or similar variations. Pay attention to the middle letter, which should be "b" instead of "k." 3. **Series Identification**: Genuine Rubycon capacitors follow specific series standards. For example, the imported YK series is rated for 85°C, whereas fake versions might claim 105°C. A deeper understanding of the technology is needed to identify such differences. 4. **Price Point**: Counterfeit capacitors are often sold at significantly lower prices—2–3 times cheaper than real ones. They usually match the price of domestic capacitors (commonly called "sapphire"). However, some unscrupulous sellers may counterfeit them to look like the real thing, even selling them at the same price. Always be cautious when purchasing to avoid unnecessary losses due to low prices.
