【New Product Release】 AEW / LEW Series Radial lead Aluminum Electrolytic Capacitors 105°C, High Capacitance

November 17, 2025

1.Introduction

With the rapid expansion of the generative AI and the server markets, there is growing demand for high-performance, space-saving power solutions. As AI technology advances, higher data processing capability is required, while downsizing and improving the efficiency of servers have become critical challenges. To meet these market needs, we have developed the AEW series (105°C, 3,000 hours guaranteed) and the LEW series (105°C, 12,000 hours guaranteed) as miniaturized, high ripple current aluminum electrolytic capacitors for power supply input applications. Compared to our conventional products, these new capacitors offer a smaller size while delivering high performance even in limited spaces. This enables further efficiency improvements and enhanced reliability in power supply designs for servers, data centers, adapters and so on. As next-generation power solutions, our new products aim to contribute to the advancement of the industry.

2.Features

The new aluminum electrolytic capacitors achieve miniaturized size and high capacitance by adopting newly developed high-capacitance electrode foil and separator. In addition, the use of a high-performance electrolyte enhances electrolyte stability and conductivity, improving overall reliability. Through these technical innovations, the new products deliver up to approximately 20% higher capacitance and up to approximately 17% reduction in volume compared with our conventional HXW and LXW series. They offer excellent choices for modern power supply designs that demand higher performance.
