3 common ceramic capacitors and their characteristics
2022.04.29
Ceramic capacitors are a general term for capacitors with ceramic materials as the medium. According to the voltage used, it can be divided into three types of ceramic capacitors: high voltage, medium voltage and low voltage. According to different temperature coefficients and dielectric constants, it can be divided into five types of ceramic capacitors: negative temperature coefficient, positive temperature coefficient, zero temperature coefficient, high dielectric constant and low dielectric constant. Compared with other capacitors, general ceramic capacitors have the advantages of higher operating temperature, large specific capacity, good moisture resistance, small dielectric loss, and a wide range of capacitance temperature coefficients. Widely used in electronic circuits, the amount is very considerable.

Crystal diodes are often represented by "D" plus numbers in the circuit, such as: D5 represents the diode numbered 5. 1. Function: The main characteristic of the diode is unidirectional conductivity, that is, under the action of forward voltage, the on-resistance is very small; while under the action of reverse voltage, the on-resistance is extremely large or infinite. Because diodes have the above-mentioned characteristics, they are often used in rectification, isolation, voltage regulation, polarity protection, coding control, FM modulation and squelch circuits in cordless telephones. The crystal diodes used in telephones can be divided into: rectifier diodes (such as 1N4004), isolation diodes (such as 1N4148), Schottky diodes (such as BAT85), light-emitting diodes, and Zener diodes. 2. Identification method: The identification of diodes is very simple. The N pole (negative pole) of low-power diodes is mostly marked with a color circle on the surface of the diode. Some diodes also use a diode-specific symbol to indicate the P pole (positive pole) or N pole. (Negative), there are also symbols marked "P" and "N" to determine the diode polarity. The positive and negative poles of the light-emitting diode can be identified from the length of the pins. The long pin is positive and the short pin is negative. 3. Test precautions: When using a digital multimeter to measure the diode, the red test lead is connected to the positive electrode of the diode, and the black test lead is connected to the negative electrode of the diode. The resistance value measured at this time is the forward conduction resistance value of the diode. The connection method of the multimeter's test leads is just the opposite.
Inductance is often represented by "L" plus a number in the circuit
2022.03.08
Inductance is often represented by "L" plus a number in the circuit, such as: L6 represents the inductance numbered 6. The inductance coil is made by winding an insulated wire around an insulated skeleton for a certain number of turns. DC can pass through the coil, and the DC resistance is the resistance of the wire itself, and the voltage drop is very small; when the AC signal passes through the coil, a self-induced electromotive force will be generated at both ends of the coil, and the direction of the self-induced electromotive force is opposite to the direction of the applied voltage, hindering the AC voltage. Pass through, so the characteristic of the inductor is to pass DC and resist AC. The higher the frequency, the greater the coil impedance. The inductance can form an oscillation circuit with the capacitor in the circuit. Inductors generally have direct marking method and color marking method, and the color marking method is similar to resistance. Such as: brown, black, gold, gold means 1uH (error 5%) inductance. The basic unit of inductance is: Henry (H) conversion unit: 1H=10^3mH=10^6uH.
Capacitors are generally represented by "C" plus numbers in the circuit
2022.03.08
1. Capacitors are generally represented by "C" plus numbers in the circuit (for example, C13 represents the capacitor numbered 13). A capacitor is a component composed of two metal films that are close together and separated by insulating materials. The characteristics of capacitors are mainly to block DC and AC. The size of the capacitor capacity is the size of the electric energy that can be stored. The blocking effect of the capacitor on the AC signal is called capacitive reactance, which is related to the frequency and capacitance of the AC signal. Capacitive reactance XC=1/2πfc (f represents the frequency of the AC signal, C represents the capacitance) The types of capacitors commonly used in telephones include electrolytic capacitors, ceramic capacitors, chip capacitors, monolithic capacitors, tantalum capacitors and polyester capacitors. 2. Identification method: The identification method of capacitance is basically the same as that of resistance, and it is divided into three types: direct marking method, color marking method and number marking method. The basic unit of capacitance is expressed in farads (F), and other units are: millifarads (mF), microfarads (uF), nanofarads (nF), and picofarads (pF).

The triode is only a general term for the three-pin amplifier device in the Chinese meaning. The triode we often say may have a variety of devices. It can be seen that although they are all called triodes, in fact, the terms in English are very different. The term triode is actually a pictographic vocabulary unique to Chinese. Electronic triode Triode This is the English translation of the word "triode" in the English-Chinese dictionary. This is related to the earliest appearance of electronic triode, so it is preconceived, and it is also the item originally referred to by the word triode in the true sense. The rest of the things that are called triodes in Chinese can never be translated into Triodes in actual translation, otherwise it will be troublesome.
