NICHICON Develops the GYE Series of High-Capacitance Conductive Polymer Hybrid Aluminum Electrolytic Capacitors

2020-10-15 | Return

NICHICON CORPORATION developed the high-capacitance GYE series of conductive polymer hybrid aluminum electrolytic capacitors featuring superior performance at high temperatures, long life, high ripple current, and low equivalent series resistance (ESR), which have seen increasing demand from the automotive and industrial equipment fields.

The new series will be exhibited at CEATEC 2020 ONLINE from Tuesday, October 20, to Friday, October 23.

Overview and Development Background
NICHICON has launched the GYA series (operation guaranteed for 4,000 hours at 125°C) and GYC series (4,000 hours at 135°C) of conductive polymer hybrid aluminum electrolytic capacitors for use in products primarily for the automotive and industrial equipment sectors where high reliability is required.

We developed the new GYE series with higher capacitance ratings than the GYA series. Offering greater capacitance with the same size capacitors, we expect the GYE series to contribute to miniaturization and weight-saving and the further optimization of circuit designs.

Features
Conductive polymer hybrid aluminum electrolytic capacitors use both conductive polymers (low ESR, high heat resistance) and electrolytic solutions (oxide film restoration) for electrolytes. Combining the two types of electrolytes give characteristics of both aluminum electrolytic capacitors and conductive polymer aluminum solid electrolytic capacitors.

The GYE series achieves high capacitance through the use of a high-capacitance anode foil and optimization of the conductive polymer material and electrolyte. The series maintains the high reliability of the existing GYA series. It is guaranteed to perform at high temperatures (125°C) over a long life (4,000 hours) and is moisture resistant with a guaranteed 2,000 hours of operation at 85°C and 85% relative humidity. In addition, the rated ripple current is 1.2 times that of the original GYA series.
