The production of capacitors

Capacitors are the most common product among many electronic components, and their application range is very wide. There are also many large manufacturers at home and abroad that are doing very well, such as Samsung, TDK, PAGOODA and other brands. Next, I will give you a popular science about the development history of capacitors.

As early as 600 BC, the phenomenon of friction discharge first appeared. It was not until 1600 that the first friction generator appeared in the world, and then the capacitor was born in 1800. Capacitors have developed over time and have gradually become heavyweight products in the electronic component industry. In 1900, electronics was born, film capacitors were born, and ceramic capacitors using titanium oxide and barium titanate came out. In 1945, multilayer ceramic chip capacitors were born and tantalum electrolytic capacitors came out.文章配图14

I believe that many friends understand the working principle of capacitors, and use voltage to make it electrify. The core is that the positive and negative charges generated by friction inside the parts generate current by attracting each other. The capacity of the capacitor to store charge is called the electrostatic capacity, and the larger the electrode area or the shorter the distance between the electrodes, the larger the electrostatic capacity. The value indicating this capacity is the relative permittivity of the capacitor.

Only capacitors that achieve the appropriate value of permittivity are the most sought-after and best-quality products on the market.

About the characteristics of Pingshang technology chip capacitors:

1. The product has high dimensional accuracy and small size, which is convenient for high-efficiency assembly of the automatic placement machine;

2. Achieved high capacitance, suitable for small and ultra-thin devices

3. The terminal electrode is a three-layer electrode, suitable for wave soldering and reflow soldering;

4. The dielectric body and the surface are made of the same material, with little impact from environmental conditions, high insulation resistance, and high reliability;

5. Meet the requirements of European ROHS environmental protection directives.
