Nichicon Develops the GYA Series of Conductive Polymer Hybrid Aluminum Electrolytic Capacitors

Nichicon Corporation announces the introduction of its GYA Series of capacitors. These high temperature, long-life, high ripple current, conductive polymer hybrid aluminum electrolytic capacitors meet automotive and industrial machinery sector demands for high-performance aluminum electrolytic capacitors.

These products will be displayed at CEATEC JAPAN 2016, held October 4 (Tuesday) to 7 (Friday) at Makuhari Messe.

Overview/Development Background

In recent years, amid electronic control and miniaturization advances in the automotive and industrial machinery sectors, circuit boards and units with aluminum electrolytic capacitors have also advanced in terms of performance and high-density mounting.

In addition, engine ECU (Engine Control Unit) units and other components are frequently installed in the engine compartment, a high temperature environment. Thus, aluminum electrolytic capacitors with a longer life and higher ripple current are now in greater demand than ever. Nichicon manufactures non-solid aluminum electrolytic capacitors using electrolyte electrolytic solution, and solid aluminum electrolytic capacitors using conductive polymer, as its core products.

Nichicon developed conductive polymer hybrid aluminum electrolytic capacitors by combining electrolyte development technologies and conductive polymer film deposition technologies. Nichicon's GYA Series is expected to contribute to higher performance and longer life in the automotive sector, other applications.

Features

Conductive polymer hybrid aluminum electrolytic capacitors use electrolyte conductive polymer and an electrolytic solution that, in addition to the high heat resistance and low ESR performance of conductive polymer, offers oxide film restoration performance utilizing electrolytic solution. Compared to non-solid aluminum electrolytic capacitors, this product has a long life of more than 1,000 hours at 125 °C and four times the ripple current. At the same time, current leakage is reduced to 1/5 that of solid aluminum electrolytic capacitors, contributing to unit energy conservation. Also, the electrolytic solution penetrates deep into etch pits, increasing capacity by approximately four times, compared to standard solid aluminum electrolytic capacitors. Nichicon’s development of electrolytic solutions with proprietary deposition technologies means a highly reliable product guaranteed for 4,000 hours at 125 °C, the highest level in the industry.
