The film capacitor is a capacitor in which a metal foil is used as an electrode and a plastic film such as polyethylene, polypropylene, polystyrene or polycarbonate is stacked from both ends and then wound into a cylindrical shape. With excellent electrical characteristics, high stability and long l

The oscilloscope of a capacitor is a widely used electronic measuring instrument. It can transform the electrical signals that are invisible to the naked eye into visible images, so that people can study the changes of various electrical phenomena. The oscilloscope uses a narrow beam of high-speed e

A multimeter of a capacitor is an electric meter that can measure voltage, current and resistance at the same time. There are a variety of gear positions, when using the two test pens respectively contact the two ends. Ohm zero is required to measure the resistance and a battery is required. Digital

The slitting machine of low-voltage capacitors, also known as slitting line, slitting machine and slitting machine, is a kind of metal cutting equipment. 1. Use: It is suitable for longitudinal shearing of metal strips and rewinding the slit strips into rolls. 2. Advantages: easy to operate, high cu

1. Capacitor seal is not enough, water vapor enters to cause oxidation, and pressure drop is reducedOnce there is a problem with the sealing of the capacitor, the withstand voltage of the capacitor must drop. This is a common problem of the capacitor, and the CBB capacitor is also unavoidable. 2. Lo

The varistor has a resistance value, but we use an ordinary universal meter, which is unable to read the number and is displayed as infinity. The method of measuring the varistor is as follows: 1 can choose varistor professional test equipment 2 You can use an oscilloscope first. Voltage test: When

In fact, the derating of CBB capacitors is very simple to calculate. Three capacitors of equal capacity, respectively C1=C2=C3=C, connected in a triangle, arbitrarily measured AB/BC/CA, the total capacity will be 3C/2. (When measuring, the internal equivalent capacitor is C2 and C3 connected in seri

Polyaniline (PANI) is one of the most attractive tantalum capacitor materials. In order to enhance electrolyte diffusion and improve the electrochemical performance of the electrode, a well-designed PANI morphology is required. The incorporation of carbon materials is also beneficial to improve the

With its low equivalent series resistance (ESR), it achieves good ripple current handling and high surge voltage ratings and self-healing properties. Film capacitors are a strong candidate for many power conditioning tasks in critical applications such as electric vehicles. Renewable energy and indu

With the rapid consumption of fuel and the increase of environmental pollution, people are increasingly demanding energy storage equipment. Traditional energy storage devices can no longer meet the needs of economic development. Lithium-ion capacitors (LIC) are a new energy storage device between su
