NICHICON Develops and Launches the GYF Series of High-Capacitance Conductive Polymer Hybrid Aluminum Electrolytic Capacitors

2022-07-19 | 返回

NICHICON CORPORATION has developed and launched the GYF series of high capacitance conductive polymer hybrid aluminum electrolytic capacitors with high ripple current and low ESR performance, which are increasingly demanded in automotive and telecommunications applications.

NICHICON will exhibit the series at TECHNO-FRONTIER 2022’s 37th Power System Japan Expo.

Overview and Development Background

Previously, NICHICON had launched the GYE series (guaranteed for 4,000 hours at 125°C). The GYF is one rank higher in capacity than the GYA series (guaranteed for 4,000 hours at 125°C) of conductive polymer hybrid aluminum electrolytic capacitors. The GYF series was developed for to markets where high reliability is required, such as automotive, industrial machinery and telecommunications markets.

GYF series offers higher capacity in the same case size as the GYE series. The GYF series will contribute to advancements in circuit design by reducing the number of capacitors resulting in lighter and smaller units.

Features

Conductive polymer hybrid aluminum electrolytic capacitors use both conductive polymers and electrolytic solutions as electrolytes and thus retain both the low ESR performance and high heat resistance characteristic of conductive polymers and the oxide film repair performance of electrolytic solutions. The GYF series combines the features of both aluminum electrolytic capacitors and conductive polymer aluminum solid electrolytic capacitors.

In terms of capacitance, the GYF series outranks the GYA series by two levels thanks to its use of high-capacitance anode foil and thin separators.

The GYF series retains the heat resistance and long life (guaranteed for 4,000 hours at 125°C of the current GYA series in addition to moisture resistance (guaranteed 2,000 hours at 85°C and 85 % RH). Its rated ripple current is 1.44 times that of the GYA series.
