450100 electrical components is a general term for all single components based on semiconductor materials, including diodes, transistors, field-effect transistors, and thyristors (the latter three are all three-terminal devices) made from various semiconductor materials. A transistor is a semiconductor device commonly used as an amplifier or electronically controlled switch. Transistors are the basic building blocks for the standard operation of computers, mobile phones, and all other modern electronic circuits. Due to their fast response speed and high accuracy, transistors can be used for a wide variety of digital and analog functions, including amplification, switching, voltage regulation, signal modulation, and oscillation. Transistors can be packaged individually or as part of an integrated circuit in a very small area that can accommodate one hundred million or more transistors.

SMD inductors are electromagnetic induction components wound with insulated wire. They belong to the category of commonly used inductor components. The function of SMD inductors: passing DC and blocking AC is a simple description; they isolate and filter AC signals, or form resonant circuits with capacitors, resistors, etc. Function of tuning and frequency selection inductors: an inductor coil connected in parallel with a capacitor can form an LC tuning circuit. Any current in the circuit through an SMD inductor generates a magnetic field, and the magnetic flux of this field acts on the circuit. When the current passing through the SMD inductor changes, the DC voltage potential generated in the SMD inductor will oppose the change in current. When the current through the inductor coil increases, the self-induced electromotive force generated by the inductor coil is opposite to the direction of the current, opposing the increase in current, while converting a portion of electrical energy into magnetic field energy stored in the inductor; when the current through the inductor coil decreases, the self-induced electromotive force is in the same direction as the current, opposing the decrease in current, while releasing stored energy to compensate for the decrease in current. Therefore, after inductive filtering, not only are the ripples in load current and voltage reduced and the waveform smoothed, but the conduction angle of the rectifier diode also increases. Inductor function 1: Color-ring inductors have a current-blocking effect: the copper core in the color-ring inductor coil always opposes changes in the current within the coil. Color-ring inductors impede the alternating current used in circuits; the magnitude of this impedance is called inductive reactance XL, measured in ohms. Its relationship with inductance L and AC frequency f is XL=2πfL. Color-ring inductors are mainly classified into high-frequency choking coils and low-frequency choking coils. Inductor function 2: Color-ring inductors have tuning and frequency selection functions: a color-ring inductor connected in parallel with an electrolytic capacitor can form an LC tuning circuit. At resonance, the inductive reactance and capacitive reactance of the circuit are equal in magnitude but opposite in direction, meaning the natural oscillation frequency f0 of the circuit equals the frequency f of the non-AC signal, so the inductive reactance and capacitive reactance of the loop are also equal. The usage frequency of color-ring inductors is generally not very high, and color-ring inductors used in circuits are generally quite stable. Inductor function 13: The main uses of color-ring inductors include signal screening, noise filtering, current stabilization, and suppression of electromagnetic wave interference. The basic function of color-ring inductors is charging and discharging, but many circuit phenomena derived from this basic charge-discharge function give color-ring inductors various different applications. Today, color-ring inductors are widely used by customers, and the role played by these small inductors should not be underestimated.

450100 Electrical Component Classification

For different application scenarios, the purpose of using varistors varies, and the voltage/current stress applied to the varistor is not the same, so the requirements for the varistor also differ. Paying attention to these differences is crucial for correct usage. Based on the purpose of use, varistors can be divided into two main categories: protection varistors and circuit-function varistors. ① Protection varistors: 1, distinguish between power supply protection and signal line/data line protection varistors, as they must meet different technical standard requirements. 2, based on the different continuous operating voltages applied to the varistor, varistors across power lines can be divided into AC type or DC type; the aging characteristics of varistors under these two voltage stresses differ. 10, based on the different abnormal overvoltage characteristics withstandable by the varistor, varistors can be divided into surge suppression type, high-power type, and high-energy type. ② Surge suppression type: refers to varistors used to suppress transient overvoltages such as lightning overvoltage and switching overvoltage. The occurrence of such transient overvoltages is random and non-periodic, and the peak current and voltage may be very high. The vast majority of varistors belong to this category. ③ High-power type: refers to varistors used to absorb continuous pulse groups that appear periodically, such as varistors connected in parallel to switching power supply converters. Here, impulse voltages appear periodically, and the period is known; the energy value can generally be calculated. Although the peak voltage is not very high, the average power is considerable due to the high frequency of occurrence. ④ High-energy type: refers to varistors used to absorb magnetic energy in large inductive coils such as generator excitation coils and lifting electromagnet coils. For these applications, the main technical indicator is energy absorption capacity. The protective function of varistors can be repeated multiple times in most application scenarios, but sometimes they are made into one-time protective devices similar to current fuses. For example, varistors with short-circuit contacts connected in parallel to the loads of certain current transformers.

450100 Electrical Component Principles

The basic working principle of fiber optic sensors is to guide light from a light source through an optical fiber into a modulator, causing the optical properties of the light (such as intensity, wavelength, frequency, phase, polarization state, etc.) to change after interacting with the parameter to be measured in the modulation zone. This is called the modulated signal light, and the measurement is completed by utilizing the influence of the measured quantity on the transmission characteristics of the light. There are two types of measurement principles for fiber optic sensors: (1) Physical property fiber optic sensor principle: physical property fiber optic sensors utilize the sensitivity of the optical fiber to environmental changes to convert input physical quantities into modulated optical signals. Their working principle is based on the optical modulation effect of the fiber, i.e., the phenomenon where light transmission characteristics, such as phase and light intensity, change when external environmental factors such as temperature, pressure, electric fields, and magnetic fields change. Therefore, if the changes in light phase and intensity through the fiber can be measured, the changes in the measured physical quantity can be determined. These sensors are also known as sensitive element type or functional fiber optic sensors. The point source beam of the laser diffuses into parallel waves, which are split into two paths by a beam splitter: one is the reference path, and the other is the measurement path. External parameters (temperature, pressure, vibration, etc.) cause changes in fiber length and optical phase, thereby generating a varying number of interference fringes. Counting the lateral movement of these fringes allows for the measurement of temperature or pressure. (5) Structural fiber optic sensor principle: structural fiber optic sensors are measurement systems composed of light detection elements (sensitive elements), optical fiber transmission loops, and measurement circuits. Here, the optical fiber serves only as a medium for light propagation, so they are also called light-transmitting or non-functional fiber optic sensors.
