In order to meet the high performance requirements of aluminum electrolytic capacitors in the automotive and industrial equipment fields, Nichicon Co., Ltd. has launched a "GYA series" conductive polymer hybrid aluminum electrolytic capacitor that supports high temperature, long life, and high ripple. .

This product will be exhibited at the 32nd Power System Exhibition held at Makuhari Messe from April 19th (Wednesday) to 21st (Friday).

Overview / development background

In recent years, the development of electronic control and miniaturization in the automotive and industrial equipment fields has advanced rapidly. As a result, the performance and high-density mounting of substrates and electronic units equipped with aluminum electrolytic capacitors have continued to develop. In addition, it is common for engines such as engine ECU units to be installed in the engine room of high-temperature environments. Therefore, aluminum electrolytic capacitors are required to have higher temperature, longer life, and higher ripple than conventional ones. As the main product, Nichicon produces non-solid aluminum electrolytic capacitors using an electrolyte as an electrolyte and conductive polymer aluminum solid electrolytic capacitors using a conductive polymer as an electrolyte. This time, it incorporates the electrolyte development technology cultivated so far. We developed a conductive polymer hybrid aluminum electrolytic capacitor with a film-forming technology of conductive polymer and put it on the market. With this product, it is expected to contribute to higher performance and longer life in various applications such as automotive applications.

Specialty

"By using conductive polymers and electrolytes as electrolytes, conductive polymer hybrid aluminum electrolytic capacitors have both low ESR performance and high heat resistance, which are the characteristics of conductive polymers, as well as the oxide film repair performance. Compared with non-solid aluminum electrolytic capacitors, the "GZA series" has achieved a long life of more than 1,000 hours at 125 ° C, and has a ripple current that is 4 times higher than the allowable ripple current. On the other hand, compared with conductive polymers Aluminum solid electrolytic capacitors reduce leakage to approximately one-fifth, contributing to the power saving of the unit. In addition, the electrolytic solution penetrates deep into the corrosion holes of the electrode foil, so it is compared with ordinary conductive polymer aluminum solid electrolytic capacitors It can obtain about 4 times the appearance rate of capacitance. By developing an electrolyte that matches the physical properties of Nichicon ’s conductive polymer film formation technology and the properties of conductive polymer films, the industry ’s highest level at 125 ° C is guaranteed. 4,000 hours of operation, achieving high reliability.
