What are the effects of film capacitors on parameter variables, including these four factors, namely, capacitance, loss tangent, insulation resistance and withstand voltage. The production process of film capacitors is also closely related to the requirements of ensuring the four parameters. The pro

There is no essential difference between the function of X capacitor and Y capacitor. The difference is their connection. It can be divided into two points:1. Difference is that the X capacitor is not grounded, and the Y capacitor must have a ground wire.2. Most X capacitors are square box shaped, a

But if the super capacitor is only discharged to 2.5V, when the system closes, it will leave quite a lot of electricity in the super capacitor. The electrical energy stored in supercapacitors is equal to CV2. For example, the 1F super capacitor is charged to 5V through your input power, so that the

When a supercapacitor is charged for a standby power system such as a solid-state drive (SSD) or a portable medical system, the value, size and cost of the supercapacitor are proportional to the required holding time. Once the user removes the system from the input power and switches to the super ca

Film capacitors are widely used, such as our common air conditioners, refrigerators, washing machines, electric cars, etc. The wide application is inseparable from the advantages of film capacitors. What are some of them? 1. Film capacitors, which are suitable for a wide range of temperatures, are r

The principle of tantalum capacitance is such that tantalum pole is easy to oxidize in air, people use its oxide film as medium, because tantalum pole is easy to oxidize, so tantalum capacitor has automatic "healing wound" repair effect, so it is durable and high reliability. Because the oxide film

The capacitor is made of a rare metal crucible. The crucible is ground into a fine powder and sintered together with other media. Tantalum capacitors have the characteristics of good stability, no change with environmental changes, large capacitance, etc. due to the inherent characteristics of metal

Q = CU, Q is the charge (capacity) stored in the capacitor, C is the capacity of the capacitor. U is the voltage across the capacitor. We know that the larger the capacity, the higher the pressure value the more expensive the price. Some unscrupulous merchants often falsify the parameters of the cer

Due to the large number of capacitor types, the capacitors will be named by the relevant brands in order to facilitate the procurement. If we grasp these named methods, we can learn about the relevant information of the capacitors. May wish to learn about the name of monolithic capacitors. The namin

Varistors are voltage limited protection devices. Using the non-linear characteristics of the varistor, when overvoltage occurs between the two poles of the varistor, the varistor can clamp the voltage to a relatively fixed voltage value, thereby achieving the protection of the subsequent circuit. W
