How to quickly choose a suitable film capacitor:1. The rated voltage of the capacitor;2. Selection of the working voltage of the capacitor;3. The choice of capacitor capacitance and wire span. Film capacitors are capacitors in which metal foil is used as an electrode, and plastic films such as polye

Film capacitors are electronic components with a wide range of applications and have gradually replaced aluminum electrolytic capacitors. Film capacitors are capacitors in which metal foil is used as an electrode, and plastic films such as polyethylene, polypropylene, polystyrene or polycarbonate ar

1. When installing capacitors, the wiring of each capacitor is connected to the bus with a separate flexible wire, do not use hard bus connection. To prevent assembly stress from causing damage to the capacitor casing and damage to the seal and cause oil leakage. 2. Any poor contact in the capacitor

Introduction to film capacitors:Due to the different capacitor dielectrics, the types of capacitors are also different. For example: paper capacitors, electrolytic capacitors, film capacitors, air capacitors and so on. Film capacitors are widely used in audio equipment, and are widely used in the cr

General capacitor failure phenomenon: capacitor open circuit, breakdown, leakage, breakdown after power on. 1. Cause of failure:1) Open circuit of componentsAfter the capacitor is opened, there is no capacitor function. After an open circuit fault occurs in a capacitor in a different circuit, the sp

Capacitors are a bit like batteries. Although they work in very different ways, they can store electrical energy. If you have read how the battery works, you should know that the battery has two electrodes. Inside the battery, a chemical reaction causes one electrode to generate electrons, and the o

Coupling capacitance: The capacitance used in the coupling circuit is called the coupling capacitance. This kind of capacitance circuit is widely used in the resistance-capacitance coupling amplifier and other capacitive coupling circuits to block DC and AC. Filter capacitor: The capacitor used in t

The Fourth Vacuum Coating Equipment has just arrived on September 12th, 2020！ High-quality products come from high-standard equipment.

Capacitors are components that can store charges and are also one of the most commonly used electronic components. There are many types of capacitors, including film capacitors, CBB capacitors, safety capacitors, etc., which are widely used in various fields. Normally, to judge the quality of the ca

1. Temperature and life of capacitor. Usually the life of the capacitor decreases with the increase in temperature, the most obvious: electrolytic capacitor. An electrolytic capacitor with a limit working temperature of 85°C can generally guarantee a normal working time of 181019 hours when working
