O que são capacitores de cerâmica? Basta ler este post.

Ceramic capacitors which take ceramic as raw material. Such as high & low dielectric constant capacitors, high & low voltage capacitors. Ceramic capacitors are electronic components used to store electrical charge. They are made by extruding high dielectric constant capacitor ceramic barium titanate, then make titanium oxide into round tubes, discs, or plates, and plating…

Capacitor de cerâmica de alta tensão com as mesmas especificações, por que os preços dos diferentes materiais são tão diferentes?

Why do high-voltage capacitors of the same specification differ in price by about 10 times due to different materials? The customer told me that a supplier’s quotation for this high-voltage ceramic capacitor is 3.8 yuan. But what you quoted is a high-voltage capacitor made of N4700 material, the price is 42 yuan, why? It turned…

Por que a capacidade dos capacitores de alta tensão decai após um período de tempo de trabalho?

First of all, for example, the N4700 ceramic we use, the temperature drift is about 20%, and it is negative temperature, that is to say, the lower the temperature, the larger the capacity, on the contrary, the higher the temperature rise, the smaller the capacity. In the high frequency and high voltage environment, the capacity…

O que é um capacitor de alta freqüência e alta tensão?

High-frequency capacitors refer to high-voltage capacitors that can operate in high-frequency environments above 1KHZ or for long-term operation in pulse frequency environments.   There are usually two types of high-frequency capacitors: one is high-frequency capacitors, mainly high-frequency circuits represented by non-destructive testing, X-ray machines, CT machines, and the general frequency is between 20KHZ and 200KHZ. …

Quais são os capacitores mais comuns?

  First: ceramic capacitorsCeramic capacitors are made by extruding a high-dielectric constant capacitor ceramic (barium titanate titanium monoxide) into a tube, wafer or disc as the medium, and plating silver on the ceramic as an electrode by sintering method. It is divided into high-frequency porcelain and low-frequency porcelain.High-frequency ceramic capacitors are suitable for high-frequency circuits…

Atenção ao uso de capacitores de cerâmica de alta tensão

First: working voltageWhen using DC rated voltage capacitors in AC circuits or ripple current circuits,Be sure to maintain the Vp-p value of the applied voltage or the Vo-p value including the DC bias voltage within the rated voltage range.If voltage is applied to the circuit, a temporary abnormal voltage may be generated due to resonance…

How do capacitors work?

Various capacitors are needed in electronic production, and they play different roles in the circuit.Similar to a resistor, it is usually referred to as a capacitor for short, represented by the letter C.As the name suggests, a capacitor is a “container for storing electric charge.” Although there are many types of capacitors, their basic structure…
