Category introduction of electronic components

Electronic components are components of electronic components and electrical small machines and instruments. They are often composed of several parts and can be used in similar products. Often refers to electrical appliances, radio, instrumentation and other industrial parts, such as capacitance, transistor, spring, spring and other sub-devices. Business opportunities trading network will give you a check of some common electronic components, so that you know more about electronic components.

Life around us without a variety of electronic products, their presence greatly enriched our lives and make our life rich and colorful, normally we use for the functions of the electronic products in time for a long time after can be very skilled to master, but know little about its internal structure.


Inductors are not used much in electronics, but they are equally important in circuits. We consider an inductor, like a capacitor, to be a storage element that converts electrical energy into magnetic energy and stores energy in a magnetic field. It often works with capacitors to form LC filters, LC oscillators, etc. In addition, people also use the characteristics of inductance, the manufacture of choke coils, transformers, relays and so on.


Capacitance is usually represented by "C" plus a number in a circuit. Capacitance is a component composed of two metal films close together and separated by insulating material. Its characteristics are mainly isolated from the direct current OF AC, capacitance capacity represents the size of the storage of electric energy, capacitance on the ac signal blocking effect called capacitive reactance, and it is related to the frequency and capacitance of the AC signal.

Crystal diode

Crystal diode this name believe many people have heard, but to let us say what it is, many people are confused. Crystal diode is made of semiconductor materials and become a kind of electronic components, in the circuit commonly used "D" plus digital representation, its main characteristic is one-way conductivity, that is, under the action of the forward voltage, the conduction resistance is very small; Under the action of reverse voltage, the conduction resistance is extremely large or infinite.

Relay is an electronic control device, it has control system (also known as the input loop) and controlled system (also known as the output loop), usually used in automatic control circuit, it is actually a smaller current to control the larger current of an "automatic switch". Therefore, it plays the role of automatic adjustment, safety protection and conversion circuit in the circuit.

In addition, the detection of electronic components is a basic skill of home appliance maintenance, and a lot of engineering maintenance and repair technology in the security industry is actually from the maintenance and repair technology of home appliances, or reference or homogeneity. How to accurately and effectively detect the relevant parameters of components and determine whether the components are normal is not a uniform thing. Different methods must be adopted according to different components to determine whether the components are normal or not. The above is the relevant knowledge of electronic components, I hope to help you.
