TETM10-14C electrical components are resistive elements with three terminals, whose resistance can be adjusted according to a specific variation pattern. A potentiometer typically consists of a resistive element and a movable wiper. When the wiper moves along the resistive element, a resistance value or voltage proportional to the displacement is obtained at the output terminal. A potentiometer can be used as either a three-terminal component or a two-terminal component. The latter can be regarded as a variable resistor. Since its function in a circuit is to obtain an output voltage that has a certain relationship with the input voltage (applied voltage), it is called a potentiometer. A potentiometer is a type of variable resistor. It usually consists of a resistive element and a rotating or sliding system, obtaining partial voltage output by moving a movable contact on the resistive element. The function of a potentiometer is to adjust voltage (including DC voltage and signal voltage) and current. Structural features of a potentiometer: The resistive element of a potentiometer has two fixed terminals. By manually adjusting the shaft or slider, the position of the movable contact on the resistive element is changed, thereby changing the resistance between the movable contact and any fixed terminal, which in turn changes the voltage and current. A potentiometer is an adjustable electronic component. It consists of a resistive element and a rotating or sliding system. When a voltage is applied across the two fixed contacts of the resistive element, changing the position of the contact on the resistive element via the rotating or sliding system yields a voltage between the movable contact and the fixed contact that is proportional to the position of the movable contact. It is mostly used as a voltage divider, in which case the potentiometer is a four-terminal component. A potentiometer is essentially a sliding rheostat. There are several styles, generally used for volume control in speakers and power adjustment for laser heads. A potentiometer is an adjustable electronic component. It is a variable resistor used for voltage division. One or two movable metal contacts are pressed tightly against the exposed resistive element. The contact position determines the resistance between either end of the resistive element and the contact. Classified by material: wirewound, carbon film, and solid-core potentiometers. Classified by the relationship between the output-to-input voltage ratio and the rotation angle: linear potentiometers (linear relationship) and functional potentiometers (curvilinear relationship). Main parameters include resistance, tolerance, and rated power. Widely used in electronic equipment for volume control in audio systems and receivers.

TETM10-14C electrical component structure

1. The cathode of an electron tube is the component used to emit electrons, divided into oxide cathodes and thoriated tungsten carbide cathodes. Generally, oxide cathodes are indirectly heated; they use a dedicated filament to heat the cathode body coated with barium oxide, etc., for thermionic emission. Thoriated tungsten carbide cathodes are generally directly heated; thermionic emission is produced simply by heating, so they serve as both filament and cathode. Theoretically, thoriated tungsten carbide cathodes have a much longer lifespan than oxide cathodes. Thoriated tungsten carbide cathodes are most widely used in high-power transmitting tubes, while oxide cathodes are generally used in transmitting tubes with an output power below 1kW. Mesh cathodes are made into a cylindrical shape using thinner thoriated tungsten wires. Their advantages are: (1) Because they are woven from many thoriated tungsten wires, they have a larger permeance coefficient. (2) It is easier to achieve a small cathode-grid spacing, which helps improve transconductance. (3) Due to the mesh structure of the filament, the current in each single filament is smaller, the local magnetic field is weaker, and thus the hum generated by the cathode current is also smaller. 2. The grids of electron tubes are divided into first grid and second grid based on their functions within the tube, sometimes also called control grid and screen grid. The main function of the first grid is to control cathode current, while the function of the second grid is to shield the first grid from the influence of the plate. The grid structure relates to its own mechanical strength and heat dissipation effectiveness, which affects whether the tube can work stably. To reduce electron transit time, the grid-cathode spacing is made very short, even less than 1mm. Therefore, manufacturers often use materials with high mechanical strength, high thermal conductivity, good radiation coefficient, and high melting point to make the grids, to avoid thermal shorting between electrodes at such small spacings. The first and second grids must be strictly aligned; this way, the screen grid captures fewer electrons, reducing screen grid dissipation, improving current distribution, and enhancing linearity. 3. The anode of an electron tube is the electrode that collects most of the electrons emitted by the cathode. During operation, due to electron bombardment of the plate surface and thermal radiation from other electrodes, a large amount of heat is generated at the plate. Since the power dissipation density of the plate is tens to hundreds of watts per square centimeter, natural radiation or conduction cooling is insufficient. Therefore, forced cooling methods must be used. Common methods include air cooling, water cooling, and evaporative cooling.

TETM10-14C electrical component applications

Photoelectric sensors using photoelectric elements as sensitive components are diverse and widely used. Based on the nature of the output quantity of photoelectric sensors, they can be divided into two categories: (1) Photoelectric measuring instruments that convert the measured quantity into a continuously changing photocurrent. These can be used to measure physical quantities such as light intensity, object temperature, light transmission capability, displacement, and surface condition. Examples include illuminance meters for measuring light intensity, photoelectric pyrometers, photoelectric colorimeters, and turbidimeters, photoelectric alarms for fire prevention, and automatic inspection devices and instruments for checking the diameter, length, ovality, and surface roughness of machined parts, all of which use photoelectric elements as their sensitive components. Semiconductor photoelectric elements are not only widely used in civil industrial fields but also hold an important position in military applications. For example, lead sulfide photoresistors can be used to make infrared night vision devices, infrared cameras, and infrared navigation systems; (8) Devices that convert the measured quantity into a continuously changing photocurrent. Various photoelectric automatic devices are made using the characteristic of photoelectric elements to output "present" or "absent" electrical signals when exposed to light or no light. Photoelectric elements are used as switching photoelectric conversion components. Examples include photoelectric input devices for electronic computers, switching temperature regulation devices, and digital photoelectric tachometers for speed measurement.

TETM10-14C electrical component types

There are many types of loudspeakers. Based on their transduction principle, they can be divided into electrodynamic (moving coil), electrostatic (capacitive), electromagnetic (armature), piezoelectric (crystal), etc.; the latter two are mostly used in rural wired broadcasting networks. Based on frequency range, they can be divided into low-frequency, mid-frequency, and high-frequency loudspeakers, which are often used as combined loudspeakers in speaker enclosures. Based on transduction mechanism and structure, they are divided into moving coil (electrodynamic), capacitive (electrostatic), piezoelectric (crystal or ceramic), electromagnetic (spring-loaded), ionophone, and pneumatic loudspeakers. Electrodynamic loudspeakers are widely used due to advantages such as good electroacoustic performance, sturdy structure, and low cost. Based on sound radiation material, they are divided into cone, horn, and diaphragm types. Based on cone shape, they are divided into circular, elliptical, dual-cone, and rubber surround types. Based on operating frequency, they are divided into bass, midrange, and treble; some are further divided into recorder-specific, TV-specific, general-purpose, and hi-fi loudspeakers. Based on voice coil impedance, they are divided into low-impedance and high-impedance types. Based on effect, they are divided into direct-radiating and ambient sound types. Loudspeakers are divided into built-in and external loudspeakers, with external loudspeakers generally referring to speaker enclosures. Built-in loudspeakers refer to MP4 players having built-in speakers, allowing users to listen to the sound from the MP4 player not only through the headphone jack but also through the built-in speakers. MP4 players with built-in speakers can operate without external speakers and avoid the inconvenience of wearing headphones for extended periods.
