The principle of ceramic capacitor and electrolytic capacitor The electrolytic capacitor is a metal foil with a positive electrode (aluminum or tantalum), an oxide film (aluminum oxide or tantalum pentoxide) that is in close contact with the positive electrode is a dielectric, the cathode is made of a conductive material, an electrolyte (the electrolyte can be [...]
一 Solid aluminum electrolytic capacitor Solid aluminum electrolytic capacitor, which differ from ordinary capacitors (ie liquid aluminum electrolytic capacitors) in that they use different dielectric materials, liquid aluminum capacitor dielectric materials are electrolytes, and solid capacitor dielectric materials are conductive. Polymer Materials. In view of the problems of liquid electrolytic capacitors, solid aluminum electrolytic capacitors came [...]
1.High stability Solid capacitor (Solid aluminum electrolytic capacitor) can continue to work stably in high temperature environments. Solid aluminum electrolytic capacitors can directly improve the performance of the motherboard. At the same time, it is suitable for power supply filtering due to its stable impedance over a wide temperature range. It can effectively provide a stable [...]
The main function of electrolytic capacitors is to stabilize the current. There are many types of electrolytic capacitors. Today I want to tell you about high frequency electrolytic capacitors. What is the high frequency electrolytic capacitor? What is the role of high frequency electrolytic capacitor? 1. What is the difference between ordinary electrolytic capacitors and high-frequency [...]
The Multilayer Chip Ceramic Capacitor (MLCC) are mainly divided into two major categories: paraelectric (class I) and ferroelectric (class II). Below them, there are many kinds of different temperature and characteristic laws, and the specific values are different. Media material. The dielectric constants of these two types of dielectric materials change with temperature, but the magnitude [...]
