As a professional capacitor customization design manufacturer, we will understand your application requirements and design needs, so as to produce products to meet your needs.


Immediate consultation


The goods taken by the agent can not pass through many channels.

Guarantee the authenticity of the quality of the goods.


Domestic renovation of old capacitors, disassembly and reprocessing products

Counterfeit and inferior products make you vulnerable. How to ensure the quality?


Domestic manufacturers have different levels of technology.Hello, but also let you have no choice.

Going to E-City to find an agent is often out of stock.How can we deliver the goods without deadline?

The price of imported capacitors is too high and the delivery time is too long.The answer is not as good as our own profession.

You are purchasing aluminium electrolysis Capacitor time Are there the following confusions?


When there are technical questions to ask the agent, sometimes

It's better to be a professional than to answer questions.


QingQuanCustomized Capacitor

Other Domestic Brand Capacitors

Professional consultation, tailor-made solutions

We have taken full account of our customers and have a strong technical reserve.

4-10℃ lower than other brands

Domestic brand

Referring to the design of foreign products, additional characteristic ion conduction and heat dissipation technology

Weak ripple resistance, increased customer purchase costs Reducing the Reliability of the Whole Machine

Very weak pressure sharing capability

Customized reserve is insufficient and incomplete

No capacity matching scheme, weak consistency

Providing capacity matching scheme with strong balance

Due to the selection of customizable capacitors with high current and overvoltage resistance

Poor extreme aluminium material, poor performance

Electrolytic Capacitor performance

Due to the selection of large holes in aluminium box, it can withstand more ripple. Improving the reliability of the whole machine greatly

4-10 ℃ higher than capsun capacitance
