serighten.com is the official website of Zhejiang Serighten Electronic Technology Co., Ltd. According to the site, the company is based in Jiangshan, Zhejiang, was founded in 2013, and has registered capital of RMB 14.99 million. Its main business covers the R&D, production, sales, and service of supercapacitors, graphene energy-storage devices, and new-energy products, with a particular emphasis on the niche category of coin-type supercapacitors.
The website mainly presents the company’s product catalog and corporate qualifications. Its products include coin-type series, State Grid-specific coin Farad capacitors, power-type series, energy-type series, horn/lead cylindrical capacitors, and supercapacitor modules made from multiple cells connected in series with balancing and voltage-regulation systems. Key selling points include high power density, fast charge and discharge, long cycle life, low leakage current, low internal resistance, ROHS lead-free compliance, and, for some models, support for operating environments from -40℃ to 85℃.
The official website does not publish prices, MOQ, lead times, or tiered quotations, which is typical for industrial components sold by inquiry. Buyers need to contact the company by phone, mobile/WeChat, or email and request a quote based on capacity, voltage, form factor, temperature range, application scenario, and whether a customized module is required.
The strengths are clear positioning and a fairly complete range of product formats, making it suitable for hardware manufacturers doing component selection or customization. The site also states that the company has participated in the drafting of several national and group standards and has received honors such as High-Tech Enterprise status, suggesting a certain level of industry experience. The drawbacks are also obvious: the website is more of a corporate showcase than a technical procurement platform, lacking complete datasheets, certification documents, test curves, reliability data, and online selection tools. Some content is repetitive, and certain news items show future dates, so buyers should further verify the accuracy of information before procurement.
It is suitable for business customers in areas such as smart meters, IoT devices, smart locks, industrial control, automotive electronics, backup power, and small energy-storage modules. For individual retail purchases or small-batch experimental procurement, the website does not show a convenient online ordering channel.
This is the official website of a Chinese company, with contact details, address, and content aimed at domestic customers, and it is usually directly accessible from within China. Before purchasing, buyers should request datasheets, sample test reports, certification documents, mass-production consistency data, and after-sales terms.
