Welcome to the official website of Zhizhong Electronics Co., Ltd.Company focus: Ceramic Capacitor, Monolithic capacitor

In a DC circuit, a monolithic capacitor is equivalent to an open circuit. A capacitor is a component that can store electrical charge, and it is also one of the most commonly used electronic components. This has to start from the structure of the capacitor. The simplest monolithic capacitor is composed of plates at both ends and an insulating dielectric (including air) in the middle. After being energized, the plates are charged to form a voltage (potential difference), but due to the insulating material in the middle, the entire capacitor is non-conductive. However, this situation is under the premise that the critical voltage (breakdown voltage) of the capacitor is not exceeded. We know that any substance is relatively insulating. When the voltage across the substance increases to a certain level, the substance can conduct electricity. We call this voltage breakdown voltage. The capacitor is no exception. After the capacitor is broken down, it is not an insulator. However, in the middle school stage, such a voltage is not visible in the circuit, so all work below the breakdown voltage and can be seen as an insulator. Ceramic capacitor
　　 However, in an AC circuit, because the direction of the current changes with time as a certain function. The process of charging and discharging a monolithic capacitor has time. At this time, a changing electric field is formed between the plates, and this electric field is also a function of time. In fact, the current is passed between the capacitors in the form of a field. In the middle school stage, there is a saying, it is called passing AC and blocking DC, which is the nature of capacitors.
