The aging characteristics of the class Ⅱ of ceramic capacitors ☀️Ageing is a unique characteristic of ceramic capacitors. As the time of delivery of ceramic capacitors increases, the capacitance of the capacitor decays. The Class Ⅰ of ceramic dielectric capacitor has no aging phenomenon; the Class Ⅱ of ceramic capacitor has an aging phenomenon. ☀️The capacitance of [...]
Please check the ceramic capacitor manufacturing process: 💥Silver Paste Spraying 👉Silver Paste Spraying is one of the methods for coating electrodes in ceramic, glass, mica and other inorganic dielectric capacitors. Its working principle is through spray paint, which uses 4 to 5 atmospheres of compressed air to spray silver paste on the surface of the medium [...]
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 [...]
The feed through capacitor is a three-terminal capacitor, but compared to the conventional three-terminal capacitor, because it is directly mounted on the metal panel, its grounding inductance is smaller, almost no lead inductance, and its input and output The ends are isolated by metal plates, eliminating high-frequency coupling. These two characteristics determine the filter effect of [...]
Here we analyze the cause of ceramic capacitor leakage current As a result, leakage of the ceramic capacitor is reduced due to insulation. The following two reasons are summarized: The first is the surface insulation degradation caused by surface contamination. Such leakage current is not very large. Generally, it is a micro-ampere level, and the [...]
