Reason one: operating voltage is too high. I believe many engineers are aware that the high voltage capacitor operating voltage can reflect the substation bus system voltage, and directly affect the capacitor life and function. The active power loss in the operation of high voltage capacitor is main

1.Check the safety gauge capacitor label for any defects and deadlines in the storage, production and use process of the guaranteed product. 2.Also check to see if the safety capacitor is after service time. 3.Safety capacitor stored in a dry place, moisture-proof, anti-chemical, anti-fire. Normally

Film capacitor manufacturers should pay attention to the selection of capacitors: rated voltage. The so-called rated voltage refers to the voltage applied to the two ends of the capacitor by the film capacitor which can work normally, stably and reliably within a certain period of time in the circui

Decoupling capacitor is a small battery to meet the current changes in the circuit to avoid the coupling interference between each other. The understanding of this can be referred to the calculation of the bulk capacitor of the power supply, which is similar to this. . The bypass capacitor is actua

The marking method of capacitors. Direct marking: use letters and numbers to mark models and specifications directly on the housing. Character symbol method: a regular combination of numbers and characters to express capacity. A unit of electrical capacity: P, N, u, m, F, etc. Is represented in the

Tantalum capacitor naming. The model names of capacitors in various countries are very different. The naming of domestic capacitors consists of four parts: Part I: use letters to denote names, capacitors for C. The second part: the material is represented by letters. The third part: the classificati

The reason for why tantalum Capacitor filter is superb. Tantalum capacitors have excellent performance. They are small volume capacitors and with large capacitance. Tantalum capacitors are very convenient for larger capacitance. There are few competitors in power filter, AC bypass and so on. Tantalu

Advantages and disadvantages of tantalum capacitors. Advantages. Tantalum capacitors are called tantalum electrolytic capacitors, and they are also electrolytic capacitors. They use metal tantalum as a medium, do not use electrolytic solutions like ordinary electrolytic capacitors, and tantalum capa

The voltage value of capacitors is a problem that technicians attach importance to, no matter what capacitor you are using, it is necessary to know the voltage value of capacitor. What we are going to talk about is about the voltage value of the ceramic chip capacitor, which can let people know the

The varistor has a large stray capacitance, when it is used in the protection of AC power system, it often forms a significant leakage current test in the normal start-up condition. For example, a varistor with a stray capacitance of 2000pf is placed in a 220 V / V / 50 Hz AC power system with a lea
