Introduce the common points and applications of several types of film capacitors: now mass-produced plastic film capacitors include polystyrene, polyethylene, polypropylene, polytetrafluoroethylene, polyester, polycarbonate, and composite films. 1) CBB22 metallized polypropylene film DC capacitor. T

The development status of my country's metallized film capacitors: since the advent of hand-produced metallized film capacitors in the 1960s, my country's metallized capacitors have roughly experienced three development waves; in the 1980s, the overproduction of color TVs was used as an opportunity

Film capacitors are electronic components, which are used in many household appliances and have a wide range of applications. Film capacitors have gradually replaced aluminum electrolytic capacitors. A film capacitor is a capacitor in which metal foil is used as an electrode, and plastic films such

The difference between safety capacitor and CBB capacitor1. Ceramic capacitors are ceramic capacitors used for high-frequency and high-voltage applications. The capacitors with rated voltages of 400V and 250V are named Y1 and Y2 capacitors, namely, safety ceramic capacitors.2. CBB capacitors are thi

The frequency of use of film capacitors is relatively high, and they are mainly used for cross-connection of analog signals and other power sources. It has many excellent features and is an excellent capacitor product. Capacitor failure:Capacitor breakdown, open circuit, lead break, insulation ruptu

SMD capacitors are classified from other capacitors. SMD capacitors are also called multilayer (multilayer, laminated) chip ceramic capacitors, also called chip capacitors and chip capacitors. SMD capacitors are divided into: NPO capacitors, X7R capacitors, Z5U capacitors, and Y5V capacitors. SMD ca

Do you know what a capacitor is? I believe many people know and have seen that capacitors bring us great convenience and can store electrical energy, such as power banks. There are also many types of capacitors. Let’s talk about pulse capacitors and hope it will help you. Introduction to Capacitors:

Film capacitors are widely used, such as our common air conditioners, refrigerators, washing machines, electric cars and so on. So, what are the advantages of film capacitors? 1. The applicable temperature range of film capacitor is relatively wide, and the temperature limitation is relatively small

1. Insulation resistance test(1) Multimeter methodThis method is suitable for measuring the insulation resistance of non-polar capacitors. When measuring, set the multimeter's electrical barrier to 10kΩ, and connect the two test leads to the two pins of the capacitor. For capacitors with small capac

1. Multimeter testing methodFor fixed capacitors above 0.01μF. The R×1k block of a multimeter can be used to directly test whether the capacitor has the charging process and whether there is internal short circuit or leakage, and the capacity of the capacitor can be estimated according to the magnit
