MCLED electrical components Germany MCLED model MCLED price

MCLED electrical components are components that can convert electrical energy into magnetic energy and store it. The structure of an inductor is similar to a transformer, but it has only one winding. An inductor has a certain inductance and only impedes changes in current. If the inductor is in a state with no current flowing through it, it will attempt to impede current flow when the circuit is connected; if the inductor is in a state with current flowing through it, it will attempt to maintain the current unchanged when the circuit is disconnected. Inductors are also known as chokes, reactors, and dynamic reactors.

MCLED electrical component classification

Classification by material: a, wire-wound resistors are made by winding resistance wire around an insulating skeleton, coated with a heat-resistant glaze insulation layer or insulating paint. Wire-wound resistors have a low temperature coefficient, high resistance accuracy, good stability, heat and corrosion resistance, and are mainly used as precision high-power resistors. Their disadvantages are poor high-frequency performance and a large time constant. b, carbon composition resistors are made by pressing carbon and synthetic plastic. c, carbon film resistors are made by depositing a layer of carbon on a ceramic tube, forming crystalline carbon on a ceramic rod skeleton. Carbon film resistors are low-cost, stable, have a wide resistance range, and low temperature and voltage coefficients, making them the most widely used resistors currently. d, metal film resistors are made by depositing a layer of metal on a ceramic tube, using vacuum evaporation to deposit alloy materials on the surface of a ceramic rod skeleton. Metal film resistors have higher accuracy, better stability, lower noise, and smaller temperature coefficients than carbon film resistors. They are widely used in instruments and communication equipment. e, metal oxide film resistors are made by depositing a layer of tin oxide on a ceramic tube, depositing a layer of metal oxide on an insulating rod. Since they are oxides themselves, they are stable at high temperatures, resistant to thermal shock, and have strong load capacity. Classified by application, there are general-purpose, precision, high-frequency, high-voltage, high-resistance, high-power, and resistor networks.

MCLED electrical component classification

Oscillators are mainly divided into RC, LC oscillators, and crystal oscillators. 1, RC oscillators that use an RC network as the frequency-selective phase-shift network are collectively referred to as RC sine wave oscillators, belonging to audio oscillators. 2, LC oscillators that use an LC oscillation circuit as the phase-shift and frequency-selective network for positive feedback are called LC oscillators. 3, crystal oscillators are oscillators whose oscillation frequency is controlled by a quartz crystal. 5. A temperature coefficient oscillator refers to an oscillator where there is a specific relationship between its oscillation frequency and temperature, meaning different temperatures correspond to different oscillation frequencies. Conversely, by measuring the output frequency of the oscillator, the temperature value can be measured.

MCLED electrical component structure

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 5 parts: the fuse element, the housing, and the support. The fuse element is the key component controlling the fusing characteristics. The material, size, 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 a larger cross-sectional area, producing more metal vapor during fusing, and are only suitable 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 a smaller cross-sectional area than low melting point elements, producing less metal vapor during fusing, and are suitable for fuses with high breaking capacity. The shape of the fuse element is divided into wire-like and strip-like. Changing the shape of the variable cross-section can significantly alter the fusing characteristics of the fuse. Fuses have various fusing characteristic curves and can be adapted to the needs of different types of protected objects.
