    SMD capacitors do not really know what kind of thing he is for ordinary people, but its application in our lives is very extensive. For example, in our common car phones and smart homes that are now hot, he is a class of new electronic components.

    SMD capacitors do not really know what kind of thing he is for ordinary people, but its application in our lives is very extensive. For example, in our common car phones and smart homes that are now hot, he is a class of new electronic components. Chip capacitors are typically used in circuits, and the types of chip capacitors used in the circuit are also very large. So how do we identify the capacitors we see as circuit components? Next, let's look at how to identify the chip capacitor?
    The first one is a more common chip capacitor. It comes in many colors, but in common it is mainly brown, gray and lavender. And this kind of ordinary capacitor, its material is mainly porcelain, its shape is very single, the appearance is also a single surface without any silk screen, and there is no polarity.
    Second, the multi-layer capacitor of the patch paper. This type of chip capacitor is quite common, but its material is mainly paper, its shape is mainly round and square, and the oval shape is generally silver white, with metallic luster, square It is brown. For this type of chip capacitor, we can see the layering of the paper media from the side.
    The third type is the chip tantalum capacitor. If you listen to this name, we can clearly know that its material is mainly 钽, which is different from the above two, its surface is silkscreen, and there are polarities. And its color is mainly black and yellow, not gray and brown. The surface of this type of capacitor will use a white silk screen to indicate the positive pole of the capacitor and will indicate its capacitance value and its operating voltage. Some manufacturers will also mark some other information on it.
    The fourth type is mainly the electrode chip capacitor. Its material is mainly electrolyte. Like the third one, its surface is also privately owned and has the presence of a motor. Its appearance is mainly aluminum. In contrast to the third type, it is mainly used to indicate the negative pole of the capacitor with a black silk screen on the surface of the capacitor, and to indicate the capacitance value and its operating voltage in the business. Occasionally, manufacturers will also mark some other information on the silk screen.
