Nantong Jianghai aluminum electrolytic capacitor enterprise inherits Japanese core technology

Jianghai co., Ltd. is a leading aluminum electrolytic capacitor company in China, specializing in the research and development, production, sales and service of capacitors and their materials and accessories.

In addition to aluminum electrolytic capacitors, the company's products also include film capacitors and supercapacitors.

Nantong Jianghai Capacitor Co., LTD., invested by Ewee in 2005, was listed in Shenzhen Stock Exchange in 2010.

From 2015 to 2020, the company's revenue grew rapidly, reaching 1.091 billion yuan in 2015 and 2.635 billion yuan in 2020, with a compound growth rate of 19.29%.

In 2020, the net profit of the company was 373 million yuan, with a year-on-year growth rate of 54.95%, and the average annual compound growth rate from 2015 to 2020 was 23.66%.

The company's revenue growth was mainly due to the high prosperity of downstream industries such as photovoltaic and new energy vehicles, as well as the demand growth caused by domestic substitution.

Q3 2021The company's gross margin was 26.23%, down 4 percentage points from the same period last year. The decrease in gross margin was mainly due to the increase in the price of aluminum, the upstream raw material, since the third quarter of last year and the increase in electricity prices in the third quarter of this year, which resulted in higher product costs.

Currently, Jianghai's capacitor product line mainly includes aluminum electrolytic capacitors, thin film capacitors and super capacitors. In 2020, aluminum electrolytic capacitors will account for the largest proportion of the total revenue, accounting for 77.9%, followed by electrode foil 7.7%, thin film capacitors 7.4% and super capacitors 6.2%.

The company's products are now widely used in household appliances, industrial control, new energy, aerospace, rail transit, electric vehicles and other fields, customers involved in many segmented industry first-line brands.

Electrode foil is the core raw material of aluminum electrolytic capacitor, and its performance directly determines the capacity and life of aluminum electrolytic capacitor.

To this end, the company continues to invest in research and development, layout of high-pressure foil formation, corrosion foil, carbon foil coating and terminal board, the company's foil formation self-sufficiency rate has reached 75%, technical performance and production efficiency maintain the domestic leading level.

The aluminum electrolytic capacitor is a capacitor made of an aluminum cylinder as a negative electrode, filled with liquid electrolyte, and inserted into a bent aluminum strip as a positive electrode.

In the electronic circuit plays the role of ac, dc resistance, filter, bypass, coupling and fast charge and discharge functions, and has the characteristics of small volume, large storage, low cost, good electrical performance, high reliability.

Aluminum electrolytic capacitors are widely used in consumer electronics, communication products, computers and peripheral products, new energy, automation and control, automobile industry, photoelectric products, high-speed railway, aviation and military equipment, etc.
