What is the chip capacitor: The chip capacitor has the ability to store electric charge. In the circuit board, "passing AC, blocking DC", "passing high frequency, blocking low frequency", etc., now circuit boards, most electronic products are inseparable Open chip capacitors.

There are many types of chip capacitors that we often come into contact with today: chip tantalum capacitors, ceramic chip capacitors, chip stacked capacitors, chip electrolytic capacitors, etc. Let me introduce several types of capacitors:

1. SMD capacitor function: This is a conventional type, and its material is porcelain. The appearance and appearance are relatively simple, there is no silk screen on the surface, and there is no polarity.贴片电容014

2. SMD electrolytic capacitor function: The material is electrolyte. There is a silk screen on the surface with polarity. The appearance is an aluminum casing. The negative electrode of the electrolytic capacitor is represented by a black silk screen, and is marked with the capacitance value and the working voltage.


3. The function of a piece of paper multilayer capacitor: its material is paper. On some components, the manufacturers have cited silk screen printing. Generally, there are two shapes: oval (silver-white with metallic luster) and square (brown). The layering of paper media can be seen from the side. There is no polarity. The size is different, but the volume is generally larger.


We can divide the chip capacitors into variable capacitors and fixed capacitors. Most of the capacitors distinguished by intermediate insulating materials are named directly by the name of the insulating material. When selecting, it should be noted that some capacitors are not suitable for high-frequency circuits, and some capacitors have polarity. Pay attention to the connection method when connecting to the circuit. These details must be done well.
