How to identify which material the smd capacitor is?
How to identify smd capacitor of different materials? The appearance recognition method of the smd capacitor is obvious, and it is more difficult to identify the same type of capacitor. The following editor will explain the method of ident

SMD capacitor reading method
Unlike resistors, the capacitance of chip capacitors is not directly marked on the surface of the capacitor. There is nothing on the surface of chip capacitors (this is also a way to distinguish chip resistors from capacitors of the same si

The effect of adding capacitors to electric vehicles
The capacitor has the function of blocking the direct current and the alternating current. The internal resistance of the battery is a few tenths of an ohm. The electric motor of the electric vehicle is resistant to the driver. It is a freq

Four common problems in inductor applications
In the actual application of inductor, unexpected situations sometimes occur, so the inductor in actual application have to pay attention to this: 1. The temperature is too high The inductor is hot during the whole process of work, causin

What effect does the positive and negative poles of SMD tantalum capacitors have when they are inserted reversely?
The distinction between the positive and negative poles of SMD tantalum capacitors is very important. If the positive and negative poles of SMD tantalum capacitors are connected reversely, the impact will be greater. Tantalum capacitors hav

Application of SMD Inductance on Charging Pile
In charging piles, electronic transformers and inductors are widely used. It is understood that the specific amount of magnetic components depends on the power of the charging pile, but at least 20 magnetic components are required in a char

How much do you know about chip resistors?
Chip fixed resistor, directly translated from Chip Fixed Resistor, commonly known as SMD Resistor, is a kind of metallic glass uranium resistor. It is a resistor made by mixing metal powder and glass uranium powder and printing it on a subs

Why is the smd inductor short-circuited, and what kind of nature will it have after the short-circuit
For smd inductor, under normal circumstances, there will be no short-circuit phenomenon. A large part of the short-circuit phenomenon is because the current in the circuit is too high, exceeding the rated current of the smd inductor, and ta

Comparison of switching diodes and Zener diodes
Switching diodes have good high-frequency performance and are mainly used in switching circuits as electronic switches, while rectifiers generally have poor high-frequency performance (the rectifiers in switching power supplies are also ver
