1. Capacitor rated voltage:Refers to the peak value of the highest DC voltage or pulse voltage that can be continuously applied to the capacitor within the rated temperature range. Considering the requirements for reliability derating, it is usually required that the actual operating voltage should

The problem of film capacitor immersion is quite biased. I believe many people are not clear. The editor just happened to have a customer to ask this question to understand it carefully. I hope this article can give you some experience and knowledge.In a customer conversation, the other party asked,

A film capacitor is a capacitor in which a metal foil is used as an electrode and a plastic film such as polyethylen, polypropylene, polystyrene, or polycarbonate is laminated from both ends and then wound into a cylindrical shape. In recent years, due to more and more extensive applications of indu

As the frequency applied across the capacitor increases, the loss of the capacitor increases, the capacity decreases, and the withstand voltage decreases. The film capacitors we produce will be tested for frequency characteristics before they are sold. Here is our test. Film capacitor operating freq

We can start with the structure of the film capacitor. The simplest capacitor is due to the dielectric structure. After electrification, the plate is charged, forming a voltage (potential difference), but in the middle due to the insulating material, it is not conductive. However, such a situation i

Today, customers asked the editors, asked us about the quality of the film capacitors, and how long the life was. After the editors answered the customer's thoughts, it was better to give everyone the knowledge of the life class of the film capacitor under the science and the factors that affected i

Capacitance is a very important parameter in selecting capacitors. A well-designed circuit has specific parameter requirements for electronic components. For a capacitor, the capacitance is related to whether the capacitor can meet the needs of the circuit, so as to ensure that the circuit can reach

The film capacitor has many excellent characteristics, non-polarity, high insulation resistance, excellent frequency characteristics (wide frequency response), and small dielectric loss. Therefore, a thin film capacitor is used in a large amount in an analog circuit. What the editor wants to tell yo

In practice, there is not always a DC bias voltage. Non-polar tantalum capacitors can also be manufactured, but they are more expensive and may not be used after storage. If two identical tantalum capacitors are connected back to back in series, a nonpolar capacitor can be obtained. The total capaci

The film capacitor has many excellent characteristics, non-polarity, high insulation resistance, excellent frequency characteristics (wide frequency response), and small dielectric loss. Therefore, a thin film capacitor is used in a large amount in an analog circuit. What the editor wants to tell yo
