The ambient temperature of the capacitor should not exceed 40 °C, the relative humidity of the surrounding air should not exceed 80%, and the altitude should not exceed 1000 m; there should be no corrosive gas or vapor around, there should be no large amount of dust or fiber; the installation enviro

Capacitor grounding is generally a filtering effect. For example, electrolytic capacitors can filter low frequencies, and ceramic capacitors can filter high frequencies. The principle is the impedance of the capacitor. The capacitance is on the AC signal path. The higher the signal frequency, the sm

We must first know why there is a "tolerance" in the capacitor. This is because the capacitor cannot be 100% accurate due to the process, and there is a certain error. A capacitor error such as capacitor Call it tolerance. In industrial production, the allowable variation range of the parameters (ma

In our lives, many things have a variety of names. Many times different people in different places call different misunderstandings and jokes. The same is true for capacitors. Are capacitors and capacitors and capacitance and capacity the same thing? 1. "Capacitor" is the abbreviation of capacitor.

The various electronic products we use today are inseparable from capacitors. Many people think that British chemist Michael Faraday is a pioneer in today's capacitors. He shows a practical example of a capacitor and how to use it in his experiments to store it. Charge, and because of Faraday's cont

The capacitor has a time problem of charge and discharge. When the AC power is in the positive half cycle, when the capacitor is charged, the current flowing through the circuit is equivalent to the path. Once the capacitor is charged, no current flows through the circuit, which is equivalent to an

2F is an abbreviation of 300V withstanding voltage, Safety Capability Safety Rating Insulation Type Rated Voltage Range Y1 double insulation or reinforced insulation ≥ 250V Y2 Basic insulation or additional insulation ≥150V ≤300V Y5P represents the material, Y5P has the best temperature compensation

JY is a Y2 capacitor, a safety capacitor, and the other is JD, which represents a Y1 capacitor. 561 is 560 PF. In the International System of Units, the unit of capacitance is farad, or abbreviation, and the symbol is F. Since farads are too large, the commonly used capacitor units are millifarads (

When using this circuit, the following things need attention: (1) Is not isolated from 220V AC high voltage, please pay attention to safety and prevent electric shock!(2) The current-limiting capacitor must be connected to the line of fire, and the withstand voltage should be large enough (greater t
