National Commission Hotline

  • 1

    Agents get the goods through multiple channels, we can not guarantee the authenticity of the quality of the goods。

  • 3

    Domestic manufacturers have technical uneven telling their own good, so that you have no choice。

  • 5

    When agents asked technical questions, sometimes irrelevant answers, not as good as our own professional

If you are the following confusion in the procurement of aluminum electrolytic capacitors



  • 2

    Domestic refurbished old capacitors, disassemble heavy substandard counterfeit products let you keep track of how to ensure quality?

  • 4

    Electronic City to find agents often ask no one to go without cargo of how delivery?

  • 6

    The price of imported capacitor is too high, delivery time is too long, less if you can not follow the requirements of the user the flexibility to customize

Qing Quan customized capacitance

  • Lower than any other brand 4-10 ℃
  • Referring to foreign products to design programs and additional special ion conduction cooling technology
  • As the use of large holes Aluminum resistance greater ripple high capacity machine reliability
  • Customizable overpressure resistance ability of the product to provide technical support
  • We have been fully taken into account for the customer, and strong technical reserves
  • Professional advice, tailor-made programs
  • Matching capacity to provide programs, balanced and strong

Electrolytic capacitor


Other domestic brand capacitors

  • Higher than capsun capacitance 4-10 ℃
  • Ripple poor, guests also reduced purchase costs increased machine reliability
  • Pressure capacity is very weak
  • Not less fully customizable reserve
  • No matching program capacity, consistency weak
  • Very poor rate of aluminum materials, poor performance
  • Domestic brands
