450300 electrical components are electronic devices made from semiconductor materials (silicon, selenium, germanium, etc.). A diode has two electrodes: the positive electrode, also called the anode, and the negative electrode, also called the cathode. When a forward voltage is applied across the two terminals of a diode, the diode conducts; when a reverse voltage is applied, the diode blocks current. The conduction and blocking states of a diode are equivalent to the closing and opening of a switch. A diode has unidirectional conductivity; when conducting, current flows from the anode through the device to the cathode. The diode is one of the earliest semiconductor devices developed, and its applications are very widespread. Especially in various electronic circuits, reasonable connections using diodes along with resistors, capacitors, inductors, and other components form circuits with different functions, enabling AC rectification, demodulation of modulated signals, limiting and clamping, as well as voltage regulation for power supplies.

450300 Electrical Component Features

A solid-state relay is a contactless electronic switch with isolation functionality. It has no mechanical contact parts during switching. Therefore, in addition to having the same functions as electromagnetic relays, solid-state relays offer compatibility with logic circuits, resistance to vibration and mechanical shock, unrestricted mounting positions, good moisture, mold, and corrosion resistance, and excellent performance in explosion-proofing and preventing ozone pollution. They feature low input power, high sensitivity, low control power, good electromagnetic compatibility, low noise, and high operating frequency. With no internal mechanical parts and a fully sealed potting structure, solid-state relays offer advantages such as vibration resistance, corrosion resistance, long service life, and high reliability. AC solid-state relays use zero-crossing triggering technology, resulting in short switching times, making them suitable for higher-frequency applications. Optical isolation is used between the input and output circuits, resulting in very low input power consumption. The output end includes protection circuitry and strong load capacity.

450300 Electrical Component Principles

A potentiometric displacement sensor converts mechanical displacement into a resistance or voltage output that has a linear or arbitrary functional relationship with the displacement, using a potentiometer element. Standard linear and rotary potentiometers can be used as linear displacement and angular displacement sensors, respectively. However, potentiometers designed for displacement measurement require a definite relationship between displacement change and resistance change. The movable wiper of a potentiometric displacement sensor is connected to the object being measured. The object's displacement causes a change in resistance at the moving end of the potentiometer. The magnitude of the resistance change reflects the magnitude of the displacement, while an increase or decrease in resistance indicates the direction of displacement. Typically, a supply voltage is applied across the potentiometer to convert the resistance change into a voltage output. In wire-wound potentiometers, the resistance changes in steps corresponding to the resistance per turn as the wiper moves, resulting in a stepped output characteristic. If such a displacement sensor is used as a displacement feedback element in a servo system, excessive step voltages can cause system oscillation. Therefore, the resistance per turn should be minimized during potentiometer manufacturing. Another major disadvantage of potentiometric sensors is their susceptibility to wear. Their advantages include simple structure, large output signal, ease of use, and low cost.

450300 Electrical Component Classification

Self-inductance occurs when current flowing through a coil generates a magnetic field around it. When the current in the coil changes, the surrounding magnetic field changes accordingly. This changing magnetic field induces an electromotive force (induced EMF) in the coil itself (EMF represents the terminal voltage of an ideal power source in an active component); this is self-inductance. An electronic component made by winding wire with a specific number of turns, capable of producing a certain amount of self-inductance or mutual inductance, is commonly called an inductor coil. To increase inductance, improve the quality factor, and reduce size, a core made of ferromagnetic material (iron core or magnetic core) is often added. Basic parameters of an inductor include inductance, quality factor, inherent capacitance, stability, rated current, and operating frequency. An inductor consisting of a single coil is called a self-inductor, and its self-inductance is also referred to as the self-inductance coefficient. Mutual inductance occurs when two inductor coils are placed close together; a change in the magnetic field of one coil affects the other. This effect is called mutual inductance. The magnitude of mutual inductance depends on the self-inductance of the coils and the degree of coupling between them. Components manufactured based on this principle are called mutual inductors.
