What are commonly used electronic components? How much do you know? For engineers engaged in the electronic components industry, electronic components need to touch and use every day, but in fact, many engineers may not understand the inside of the door. The following are the top ten electronic components commonly used by engineers, as well as related basic concepts and knowledge, and learn with you.
1, as a worker in the electronic components industry, resistance is well known. There is no doubting its importance. "Resistance is the most commonly used component in all electronic circuits." Resistance, because the material blocks the current, it is called a resistive material. The resistance causes a change in the electron cycle, the lower the resistance, the greater the electron cycle, and vice versa. A substance with no or little resistance is called an electric conductor and is called a conductor. Materials that cannot form current transmission are called electrical insulators and are called insulators. Resistance is represented by the "R" number in the circuit. For example, R1 means the resistance number is 1. The main functions of resistance in circuit are shunt, current limit, partial voltage, bias and so on.
2. Capacitance refers to the charge storage at a given potential difference; Record for; C, farad is international unit (F). In general, charge forces and moves in an electric field. When there is a medium between the conductors, it will hinder the movement of the charge, so that the charge will accumulate on the conductor; The most common example is two parallel metal plates. It is also the common name of capacitor.
3, crystaldiode semiconductor ends of solid state electronic devices. The main characteristic of these devices is the nonlinear current-voltage behavior. Since then, with the development of semiconductor materials and technologies, different semiconductor materials, doping distributions and geometric structures have been used to develop crystal diodes with various structures and different functions. Manufacturing materials include germanium, silicon and compound semiconductors. Crystal diodes can be used to produce, control, receive, convert, amplify signals and convert energy. Crystal diodes are usually used for "D" digital representation in circuits, for example: D5 for diode number 5.
4, voltage regulator diode (also known as Zener diode) is a semiconductor device, with high resistance before the critical reverse breakdown voltage. Voltage regulator diodes are often used in circuit "ZD" digital representation, for example: ZD5 for No. 5 regulator tube.
5, inductance Inductance: when the coil through the current, the formation of magnetic field induction in the coil, the induced magnetic field will produce induced current, to resist the current in the coil. We call this interaction between the current and the coil inductance resistance, or inductance, in "Henry" (H). Inductance elements can also be used to make inductance elements.
