Richardson Electronics Now Offering Pureechem Ultracapacitors

LaFox, IL, October 22, 2020 – Richardson Electronics, Ltd. (NASDAQ: RELL) announced today the availability of Pureechem ultracapacitors.

Located in Chungcheongbuk-do Korea, Pureechem manufactures ultracapacitors that have low internal resistance (ESR), larger capacity per unit volume, and substantial long life. These ultracapacitors are available in 3F-100F, 2.7-3.0V radial cells, or 5.4-6.0V module packages. Common applications include automatic meter reading (AMR), data storage, GPS tracking, uninterruptible power supplies (UPS), portable electronics, and cordless tools.

Pureechem’s Purixel Ultracapacitor is unique in that it uses an electrode binding technology created by its research and development team to produce better conductivity and increased storage capacity. The increased binding strength between the current collector and electrode layer devices enhances the performance of the ultracapacitor. This results in excellent performance and greater durability.

“We are thrilled to add Pureechem to our growing list of ultracapacitor partners. This technology is continually evolving and we look forward to how it will benefit every day users,” said Greg Peloquin, Executive Vice President of Richardson Electronics’ Power & Microwave Technologies group.

“We are pleased Richardson offers a global distribution network and an excellent solution. There is no doubt that the combination of our supercapacitors, which can be used in a variety of applications, and Richardson’s team, will create tremendous synergy. We look forward to our future success,” said Pureechem’s Chief Executive Officer Han-Joo Kim
