Miniaturization in electronics has been generating market interest in SMD aluminum electrolytic capacitors, and Chinese manufacturers have taken heed and continue improving their products’ capacitance and operating life span. There are companies that offer components comparable in performance to major brands such as Nichicon.
In addition to chip aluminum electrolytic capacitors, single-ended, screw-type, snap-in and solid-state units can be sourced in China. These are widely used in TVs, computers, communication power supplies, converters, vehicles, air-conditioners, wind turbines as well as military, space and aviation applications.
The typical specifications are a capacitance of 1 to 82,000µF and a rated voltage ranging from 6.3 to 1,000V. These components, produced using domestically sourced materials, can usually last 1,000 hours at 105 C operating conditions.
Aluminum electrolytic capacitors account for more than one-third of China’s manufacturing industry for capacitors, according to Chinabaogao. Zhiyan Consulting said that their volume reached 98.394 billion units in 2023.
Globally, the country leads in the Asia-Pacific region, with Market Reports World attributing this dominance to “robust domestic demand, supportive policies and a strong manufacturing base.”
