Jianghai Capacitor Co. has grown since its creation in 1958 to become the largest Chinese manufacturer of Aluminium Electrolytic, Film & Energy storage capacitors today.  While Jianghai began with the production of specialty chemicals (e.g. Electrolyte solutions), they moved to production of Aluminium Electrolytic Capacitors in 1970.  More recently, Jianghai extended its production range by integrating high and low voltage anode foil etching and forming facilities, also plastic film manufacturing.  All our factories are located in mainland China: the most important are in Nantong (north of Shanghai) and Inner Mongolia.

Jianghai has expanded rapidly since their entry into the stock market in 2010.  Jianghai has over 1500 employees, producing in excess of 4 billion Capacitors each year, generating revenues in excess of 450 million USD.  For 23 successive years, Jianghai has been elected by China's Electronic Component Industry Association as one of their Top-100 enterprises.  With R&D at its heart, the Jianghai HQ includes the Capacitor Engineering & Technological Research Centre of Jiangsu Province and a state-level Post-Doctoral Scientific Research location. Through their years of demanding research work, it owns 7 state-level new products, 33 domestic authorized & accepted patents and 53 international patents.

Jianghai's wide product range comprises of ALuminium Electrolytic Capacitors for demanding applications in Screw Terminal , Snap-in, Radial and Polymer (Leaded and SMD).

In 2012, the product portfolio was complemented by a range of Power DC Film Capacitors & EDLC Super Capacitors. More recently, innovative Lithium-Ion Capacitors and AC Film products have been launched.
