The advantages of ceramic capacitor: 1. The rising speed in high current is also applicable to the non inductive structure of the larger circuit than the normal consumption current. 2. The extra series structure is suitable for high voltage and long lasting operation. 3, capacity loss will result in

3) The surge protection is the connection between the pressure sensitive resistance contacts, which is mainly to prevent the induction charge switch from being burned out by the arc, and the voltage sensitive resistor can be connected in parallel with the contact point, so that it can play a very go

1) Surge protection is achieved by connecting the varistor with the power cord or between the power line and the earth. As a varistor, its most representative use is an important protection for electronic products when the signal line of the power line and long distance transmission is struck by lig

For example, in a voltage stabilizing circuit, the capacitance of a certain ESR will produce a feedback circuit action when the load occurs instantaneously. This fast response, at the expense of a certain transient performance, gets the subsequent quick adjustment ability, especially the slow respon

ESR is the abbreviation of the three words of EquivalentSeriesResistance. It is translated as "equivalent series resistance". In theory, a perfect capacitor does not produce any energy loss itself, but in fact, because of the resistance of the material that makes the capacitor, the dielectric of the

The structure and composition of the CBB capacitor: The principle of CBB capacitance is actually relatively simple. It is two parallel strip plate, middle insulation medium composition core, two plate each has one elicitation, that is two electrode. Metal deposits of CBB metallized film are deposite

There are three main aspects of the role of ceramic capacitor:1. Capacity loss is high stability with the temperature frequency.2. Special series structure is suitable for high voltage and long term operation reliability.3. High current climbing rate and suitable for large current loop sensorless st

High voltage ceramic capacitor is a capacitor with ceramic material as its medium. The main characteristic of high voltage ceramic capacitor is small volume and high pressure. High voltage ceramic capacitor is a circular plate capacitor with ceramic material as the medium. In the "ceramic" capacitor

Trimmer capacitor is also called semi adjustable capacitor, and its capacity is between 5 and 45pF. There are many kinds of them, and the following are the following: 1) Ceramic trimmer capacitor: characterized by abrasion resistance and long service life.2) Tube type trimmer capacitor: also known a

Capacitors are usually silent when they are running, but sometimes exceptions. The causes of the sound are as follows: (1) Casing discharge. The sleeve of the capacitor is an assembler. If the open space is too long, the rain enters between the two layers of casing, and after the voltage is added, i
