Product News September 29, 2016

Nichicon Corporation announces the addition of a 600V miniature snap-in terminal aluminum electrolytic capacitor to the LGN Series. Developed primarily for use in industrial machinery and high voltage inverter circuits. Marketed to the renewable energy market, mass production of this product began in April 2016.
 These products will be displayed at CEATEC JAPAN 2016, held October 4 (Tuesday) to 7 (Friday) at Makuhari Messe.

Overview/Development Background

There is increasing demand for higher voltage resistance aluminum electrolytic capacitors for use in inverter power sources and other control circuitry. Because of advances being made in high voltage systems as a result of increasing demands for high-efficiency and energy conservation. Demand is particularly strong for solar and wind power generators in the renewable energy market. Prior to this introduction the LGN Series had a maximum voltage rating of 500V. The addition of the 600V ratings makes the LGN series the highest rated voltage in the industry. The LGN Series is the choice for power electronics devices that place a heavy emphasis on energy-efficient operation.


The LGN Series uses a highly reliable electrodes that has been formed with high withstand voltage oxide film. The LGN Series is the industry’s highest voltage employing electrolytic solution and high-withstand-voltage electrolysis paper with enhanced film restoring capacity at high voltages offering long-term stability. With a newly developed electrolytic solution that can withstand 600V at 105°C, we have been able to achieve approximately 20 to 30% of the high breakdown voltage. By increasing the rated voltage compared to our current products, customers who develop power conditioners used by large-scale solar power systems when the capacitors are connected in series a reduction in parts needed is achieved. For example, to generate 1,200V, three 400V units are required, but only two of these new 600V products are necessary. This enables the saving of space in circuit design.
