Patch component identification, the patch component on the board cannot be identified. Help me identify it. A and b are patch varistors.

C is the patch transistor.

D is patch inductor or patch high frequency transformer.

E is a patch diode.

Please help me identify the composition of the patch, that is, you can at least take a photo for me to see what material it is. Generally, mobile phone motherboards are packaged with capacitive resistors of 0402 or even 020 1, and there is no screen printing on the surface. If 220 is an inductance, it is 22UH. If you see the resistance of 0603 or above packages. That's 22 ohms.

I don't know the electronic components of the patch. If it is a domestic driving recorder, it is probably a product developed by the manufacturer to prevent others from imitating it, and then marked with a special logo, which does not represent the model of the electronics industry. If there is a circuit foundation, according to the peripheral components, draw a schematic diagram and analyze its function. A 5-pin ic should not have a very complicated ic. I suggest you upload a picture for us to see or contact the manufacturer directly.

How to identify patch components? If the component itself is involved,

The resistance value is printed on the patch resistor, and there is no word on the patch capacitor (I mean ordinary patch capacitor, with polar capacitor such as tantalum capacitor, but the shape and resistance are very different, so it is easy to distinguish). Based on this, it can be judged whether the element is a resistor or a capacitor.

The identification of patch components is patch triode, which can be divided into MU, G 1 and 2L.

Identification of small patch components? Thin, with black paint on the surface, is a resistor; The higher one is the yellow capacitor; The height of the capacitor is almost the same as that of the inductor; The resistance and capacitance on the mobile phone are mainly small materials of 0402, and the resistance and capacitance values are not visible. If you want to know the value, you can only measure the resistance and capacitance with an instrument, and the resistance can be measured with a multimeter.

Help solve the identification problem of several patch components. This thing can't be found online. ...

If it is a model, you should say what it is for.

220 is a resistance of 22 ohms, and the others can't be found.

What brand of motherboard do you have?

I am a computer repairman. I'm going to check the information, and I forgot a little.

I can't find it. I'm telling you, everything from every motherboard manufacturer is confidential. If you really want to know, call them and let them tell you.

Find a patch component on the notebook motherboard to identify A 106 as a patch tantalum capacitor, with voltage resistance of 10V and capacity of 10 microfarads.

How to identify the specification/model/size of the patch assembly? There is so much knowledge about pasting that it is difficult to help you browse the information completely here. I recommend you to go to the library or bookstore for a day, and you will understand something.
