Dongguan Gonghe Electronic Co., Ltd.

Dongguan Gonghe Electronic Co., Ltd. is based in China and lists five active products in its catalogue. All products belong to the capacitor family, specifically supercapacitors used for high‑power energy storage. The catalogue includes a generic “Super capacitor” entry and four voltage‑specific models rated at 2.7 V with capacitance values of 1 F, 5 F, 10 F and 100 F. The 100 F unit is recorded under HS code 8532.29 and is described as having activated carbon electrodes, an organic electrolyte and an aluminum/steel housing. The supplier is classified as an imported tier with a harbor trust rating.

The supplier’s catalogue contains a basic “Super capacitor” and four 2.7 V supercapacitors with nominal capacitances of 1 F, 5 F, 10 F and 100 F. In the industry, supercapacitors of this voltage are typically classified under IEC 62391 and IEC 61960, with capacitance tolerances of ±10 % and equivalent series resistance (ESR) values ranging from a few milliohms to several tens of milliohms depending on size. Common material constructions include activated carbon electrodes, organic electrolytes such as ethylene carbonate‑based solutions, and metal housings of aluminum or steel, matching the material description of the 100 F model. Buyers often select grades based on energy density (typically 5 - 10 Wh/kg for carbon‑based cells), operating temperature range (‑40 °C to +65 °C), and cycle life (over 500,000 cycles for high‑quality units).
