NICHICON Expands Ratings for GYC Series ofConductive Polymer Hybrid Aluminum Electrolytic Capacitors
NICHICON CORPORATION has expanded the GYC series to include φ10×16.5L-sized capacitors. The GYC
series of highly heat-resistant conductive polymer hybrid aluminum electrolytic capacitors with high ripple current
and low ESR performance are increasingly required in the automotive and telecommunications.
NICHICON will exhibit this product at the Automotive Engineering Exposition 2024 to be held at PACIFICO
Yokohama from May 22 to 24.

Overview and Development Background
NICHICON previously launched the GYC series (guaranteed for 4,000 hours at 135°C or 125°C) and otherproducts that enable higher heat resistance and higher ripple current than the conductive polymer hybrid
aluminum electrolytic capacitors of the GYA series (guaranteed for 4,000 hours at 125°C). Nichicon introduced
these products to markets that demand high reliability, including the automotive, industrial equipment, andtelecommunications.
NICHICON has now added a new φ10×16.5L size (rated to 25V, 35V, 50V, and 63V) to the GYC series. The
expanded ratings will enable Nichicon to offer a wider range of capacitors to meet various applications andcontribute to further performance enhancement and optimization of set devices.

Features
Conductive polymer hybrid aluminum electrolytic capacitors use both conductive polymers and electrolytic
solutions for electrolytes. Combining the two types of electrolytes means the GYC series has characteristics ofboth aluminum electrolytic capacitors (oxide film repair) and conductive polymer aluminum solid electrolytic
capacitors (low ESR performance and high heat resistance).
The new φ10×16.5L size that has been added to the existing size range from φ6.3×5.8L to φ10×12.5L
Capacitances up to 1.5 times higher than the φ10×12.5L product in the GYC series and ripple currents up to 1.4
times other capacitors in the GYC series with the same guaranteed life.
The trend toward electric vehicles such as EVs and PHEVs is expected to accelerate further and the newcapacitors of the GYC series will contribute to higher performance in circuits that require high capacitance andhigh ripple current. The new values will assist in the miniaturization of circuits by reducing the number ofcapacitors required.
