103714 electrical components are parts of electronic components and small machines and instruments. They often consist of several parts and can be used interchangeably within similar products. The term commonly refers to certain parts in the electrical, radio, and instrumentation industries, serving as a general term for electronic devices such as capacitors, transistors, hairsprings, and mainsprings. Common examples include diodes. Electronic components include: resistors, capacitors, inductors, potentiometers, electron tubes, heat sinks, electromechanical components, connectors, discrete semiconductor devices, electroacoustic devices, laser devices, electronic display devices, optoelectronic devices, sensors, power supplies, switches, micro special motors, electronic transformers, relays, printed circuit boards, integrated circuits, various circuits, piezoelectric materials, crystals, quartz, ceramic magnetic materials, substrate boards for printed circuits, special materials for electronic functional processes, electronic adhesive (tape) products, electronic chemical materials and parts, etc.

103714 electrical component features

Solid-state relays are contactless electronic switches with isolation functionality. They have no mechanical contact parts during switching. Therefore, in addition to having the same functions as electromagnetic relays, solid-state relays offer logic circuit compatibility, resistance to vibration and mechanical shock, unrestricted installation 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. Solid-state relays have no internal mechanical parts and adopt a potting fully sealed structure, providing 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 terminal has a protection circuit and strong load capacity.

103714 electrical component principles

A resistor consists of three parts: the resistive element, the skeleton, and the leads (for solid-core resistors, the resistive element and skeleton are combined into one), but only the resistive element determines the resistance value. The volt-ampere characteristic is represented by a graphical curve showing the relationship between voltage and current at the resistor terminals. When voltage and current are proportional (the characteristic is a straight line), it is called a linear resistor; otherwise, it is called a non-linear resistor. The rated power of a resistor refers to the maximum power allowed to be dissipated when working continuously at the rated temperature (maximum ambient temperature) tR. For each type of resistor, a maximum working voltage is also specified. This means that even if the rated power is not reached, the maximum working voltage must not be exceeded when the resistance value is high. The rated power of a resistor refers to the maximum power allowed to be consumed during long-term continuous operation in DC or AC circuits. Load characteristics: When the ambient working temperature is below tR, the resistor must not exceed its rated power. When the temperature exceeds tR, the load power must be reduced. Each type of resistor has specified load characteristics. In addition, the allowable load is correspondingly reduced under low atmospheric pressure. Under pulse load conditions, the average pulse power is far lower than the rated power, and separate regulations generally apply.
