Brief introduction of screw terminal electrolytic capacitor in Shanghai BIT-CAP Technology Center

 

A  Our electrolytic capacitor features (core technology)

 

Small size, long life

 

ES3 series can replace the 85℃, 2000h products on the market, but the volume is  25% smaller than similar products,, and the life can reach 85 degrees 3000h, generally applicable to all types of industrial power equipment.

ES6 series can replace the 85 degree,5000h product on the market, but the volume is reduced by 15% and the life is up to 85 degree,6000h, which is generally applicable to frequency converter equipment.

EL20 series is equivalent to the market of 85 degree, 10000h products, but the volume reduced by 10%, life  20000h, applicable to the durability of the special requirements of high precision equipment.

 

B  Characteristics of electrical performance parameters:

 

1, good consistency of product capacity. The tolerance range shall be within the range of ±10% (the tolerance range of the normal product is ±20%)

 

2 low leakage. The maximum value is 5 minutes and the test is less than 0.01CV or 1.5mA (regular product is controlled by 0.02CV or 5mA)

 

3 low loss value. The maximum loss is 18% (routine 25%)

 

C high security design

 

1 ensure that the cover plate safety valve is released safely under excessive or over current condition.

 

2 Insulated plastic sleeves are designed by thickening and double deck to ensure good insulation performance.

 

Special assembly process (laser welding process, no glue core package process, negative foil lift process) ensure the low internal resistance and good heat dissipation performance of products.

The center temperature of the product is measured at rated voltage and rated ripple current, and the temperature is not more than 5 degrees centigrade;

 

D special requirements for key raw materials.

 

1. the cathode foil is made of imported optical foils of 99.99% purity in Japan. The positive characteristic of this kind of positive foil is the high specific volume, good consistency and the

value of the low leakage current.

2 sealing cover adopt bakelite cover plate, and screw terminal using M6 terminal design, the biggest characteristic of the material is low CL- content, low contact resistance, high temperature

resistance, and has the characteristics of high ripple current.

 

3 Electrolyte is developed with Japan, Toyama joint , has high stability and long life characteristics
