Porcelain chip capacitors are made by extruding a high-dielectric constant capacitor ceramic (barium titanate titanium monoxide) into a tube, wafer or disc as the medium, and plating silver on the ceramic as an electrode by the firing method. It is divided into high-frequency porcelain and low-frequency porcelain. Porcelain chip capacitors with a small positive capacitance temperature [...]
What are the commonly used materials for ceramic capacitors, and which ones are commonly used for ceramic capacitors: Y5P; Y5V; Y5U; X7R; NPO. What are the commonly used materials for ceramic capacitors，So what do these materials mean? The first digit indicates low temperature, the second digit indicates high temperature, and the third digit indicates deviation. ♦ [...]
What is a feedthrough capacitor? Type of feedthrough capacitor? The through-core capacitor, because it is coated with a metal layer on the porcelain tube, forming two poles inside and outside. Because the tube is empty, it is called a feedthrough capacitor. It is a three-terminal capacitor, but compared with ordinary three-terminal capacitors, because it is directly [...]
The feedthrough capacitor is a three-terminal capacitor, but compared with the ordinary three-terminal capacitor, because it is directly mounted on the metal panel, its grounding inductance is smaller, and there is almost no influence of lead inductance. In addition, its input and output The terminal is isolated by a metal plate to eliminate high frequency coupling. [...]
The dielectric of the feedthrough capacitor it is a ceramic medium, and the capacity of the ceramic capacitor will change with the change of the ambient temperature. This capacity change will affect the filter cut-off rate of the filter. The capacity temperature change rate of ceramic capacitors is determined by the ceramic medium itself. Therefore,the dielectric [...]
The reason why switching power supplies choose High frequency low resistance capacitor: The output filter electrolytic capacitor device in the switching power supply has a sawtooth voltage frequency of up to tens of kHz, or even tens of MHz. At this time, the capacitance is not its main indicator. The standard for the quality of capacitors [...]
Compared with batteries and traditional physical capacitors, the characteristics of features of super capacitorsare mainly reflected in: (1) High power density. It can reach 102～104 kW/kg, which is much higher than the power density level of batteries. (2) Long cycle life. After a few seconds of high-speed deep charge and discharge cycles of 500,000 to 1 [...]
Film capacitors use metal foil as electrodes, and are divided into Mylar capacitors, PP, and PS capacitors. How to detect the quality of film capacitors? How to detect the quality of film capacitors?1. First look at the appearance. If there is a problem with the appearance, the film capacitor is likely to have a problem. 2. [...]
Steps to explain the use of film capacitors Film capacitors use organic film as the medium. When they exceed the rated voltage and rated current, flames may occur and the capacitor may be damaged. Please use the correct circuit. 1. Circuit design Please confirm that the use of film capacitors is limited to the specified rated [...]
Monolithic capacitors and ceramic chip capacitor are both ceramic capacitors. They are different in overall structure, appearance, characteristics, capacity, withstand voltage, and application. 1.Overall structure Monolithic capacitor are another name for multilayer ceramic capacitor. Monolithic capacitor are composed of a multilayer dielectric and multiple pairs of electrodes, while ceramic capacitor are generally composed of a layer [...]
