imo 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 of 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 oscillators. Transistors can be independently packaged or integrated into a very small area as part of an integrated circuit containing one hundred million or more transistors.

A thermopile is a pyroelectric infrared sensor, a device composed of thermocouples. It is widely used as a temperature detection device in fields such as ear thermometers, radiation thermometers, electric ovens, and food temperature detection. It consists of two or more thermocouples connected in series, where the thermoelectric potentials output by each thermocouple are superimposed. It is used to measure small temperature differences or average temperatures. Structure of a thermopile: The radiation receiving surface is divided into several sections, each connected to a thermocouple; connecting them in series forms a thermopile. Depending on the application, practical thermopiles can be made in wire-type and thin-film types, as well as multi-channel and array-type devices.

The rated current of the fuse element is not equal to the rated current of the fuse. The rated current of the fuse element is selected based on the load current of the protected equipment. The rated current of the fuse should be greater than the rated current of the fuse element and determined in coordination with the main electrical appliance. The fuse mainly consists of 3 parts: the fuse element, the housing, and the support. The fuse element is the key component controlling the fusing characteristics. The material, dimensions, and shape of the fuse element determine the fusing characteristics. Fuse element materials are divided into two categories: low melting point and high melting point. Low melting point materials, such as lead and lead alloys, have a low melting point and melt easily. Due to their higher resistivity, they require larger cross-sectional dimensions for the fuse element, generating more metal vapor during fusing, making them suitable only for fuses with low breaking capacity. High melting point materials, such as copper and silver, have a high melting point and do not melt easily. However, due to their lower resistivity, they can be made with smaller cross-sectional dimensions than low melting point fuse elements, generating less metal vapor during fusing, making them suitable for fuses with high breaking capacity. The shape of the fuse element is divided into wire-type and strip-type. Changing the shape of the variable cross-section can significantly alter the fusing characteristics of the fuse. Fuses have various fusing characteristic curves, suitable for the needs of different types of protected objects.

Optical measurement and control systems are diverse, developed based on different principles of how luminous flux acts on photoelectric components. According to the nature of the output of the photoelectric component (optical measurement and control system), they can be divided into two categories: analog photoelectric sensors and pulse (switching) photoelectric sensors. Analog photoelectric sensors convert the measured quantity into a continuously changing photocurrent, exhibiting a single-valued relationship with the measured quantity. Analog photoelectric sensors can be classified into three major types based on the method of measuring the target object: transmission (absorption) type, diffuse reflection type, and shading (beam blocking) type. Transmission type refers to placing the measured object in the optical path, where light energy emitted by a constant light source passes through the object, is partially absorbed, and the transmitted light is projected onto the photoelectric component. Diffuse reflection type refers to light from a constant source being projected onto the measured object, reflecting off its surface, and then projecting onto the photoelectric component. Shading type refers to the scenario where the luminous flux from the light source is partially blocked by the measured object, causing a change in the luminous flux projected onto the photoelectric component; the degree of change depends on the position of the measured object in the optical path. Photodiodes are the most common light sensors. The appearance of a photodiode is similar to that of a standard diode. When there is no illumination, it behaves like a standard diode with a very small reverse current, known as the dark current of the photodiode. When illuminated, carriers are excited, generating electron-hole pairs, known as photo-carriers. Under the influence of an external electric field, these photo-carriers participate in conduction, forming a reverse current much larger than the dark current, known as photocurrent. The magnitude of the photocurrent is proportional to the light intensity, allowing an electrical signal that varies with light intensity to be obtained across the load resistor.
