LUMTEC electrical components German LUMTEC models LUMTEC prices

LUMTEC electrical components are devices for detachable (active) connection between optical fibers. They precisely align the end faces of two optical fibers to maximize the coupling of light energy from the transmitting fiber into the receiving fiber, and minimize the impact on the system caused by their insertion into the optical link. This is the basic requirement for fiber optic connectors. To a certain extent, fiber optic connectors affect the reliability and various performance metrics of optical transmission systems.

LUMTEC electrical component parameters

The main parameters of transistors include current amplification factor, dissipation power, frequency characteristics, maximum collector current, maximum reverse voltage, and reverse current. Amplification factor: The DC current amplification factor, also known as the static current amplification factor or DC amplification ratio, refers to the ratio of the transistor collector current to the base current when there is no varying signal input under static conditions. AC amplification factor: The AC amplification factor, also known as the AC current amplification factor or dynamic current amplification factor, refers to the ratio of the change in transistor collector current to the change in base current under AC conditions. Dissipation power: Dissipation power, also known as the maximum allowable collector dissipation power PCM, refers to the maximum collector dissipation power when the transistor parameter changes do not exceed the specified allowable values. Dissipation power is closely related to the transistor's maximum allowable junction temperature and maximum collector current. During use, the actual power consumption of the transistor must not exceed the PCM value; otherwise, the transistor will be damaged due to overload. When the operating frequency of the transistor exceeds the cutoff frequency, its current amplification factor decreases as the frequency increases. The maximum oscillation frequency refers to the frequency at which the transistor's power gain drops to 7. Typically, the maximum oscillation frequency of high-frequency transistors is lower than the common-base cutoff frequency, while the characteristic frequency is higher than the common-base cutoff frequency and lower than the common-collector cutoff frequency. Maximum current: The maximum collector current refers to the maximum current allowed to pass through the transistor collector. Maximum reverse voltage: The maximum reverse voltage refers to the highest operating voltage allowed to be applied to the transistor during operation. It includes the collector-emitter reverse breakdown voltage, collector-base reverse breakdown voltage, and emitter-base reverse breakdown voltage. Collector reverse breakdown voltage refers to the maximum allowable reverse voltage between the collector and emitter when the transistor base is open. Base reverse breakdown voltage refers to the maximum allowable reverse voltage between the collector and base when the transistor emitter is open. Emitter reverse breakdown voltage refers to the maximum allowable reverse voltage between the emitter and base when the transistor collector is open. The reverse current between the bases, also known as the collector junction reverse leakage current, refers to the reverse current between the collector and base when the transistor emitter is open. The reverse breakdown current between the emitters refers to the reverse leakage current between the collector and emitter when the transistor base is open, also known as the penetration current. The smaller this current value, the better the transistor performance.

LUMTEC 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 7 parts: the fuse element, housing, and 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 fuse easily. Due to their higher resistivity, they require larger cross-sectional dimensions for the fuse element, 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 are not easy to fuse. However, due to their lower resistivity, they can be made with smaller cross-sectional dimensions than low melting point fuse 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-shaped and strip-shaped. Changing the shape of the variable cross-section can significantly alter the fusing characteristics of the fuse. Fuses have various different fusing characteristic curves, suitable for the needs of different types of protected objects.

LUMTEC electrical component features

LED lamps are light-emitting diodes, using solid semiconductor chips as the light-emitting material. Compared with traditional lamps, LED lamps are energy-efficient, environmentally friendly, and offer good color rendering and response speed. (1) Energy efficiency is the most prominent feature of LED lamps in terms of energy consumption. The energy consumption of LED lamps is one-tenth that of incandescent lamps and one-quarter that of energy-saving lamps. This is a major feature of LED lamps. People today advocate energy conservation and environmental protection. It is precisely because of this energy-saving feature that LED lamps have a wide range of applications and are very popular. (2) They can operate in high-speed switching states. When walking on the street, one will find that every screen or image composed of LED is ever-changing. This indicates that LED lamps can perform high-speed switching operations. However, the incandescent lamps we usually use cannot achieve such an operating state. In daily life, if the switching frequency is too high, it will directly cause the filament of the incandescent lamp to break. This is also an important reason why LED lamps are popular. (3) Environmental friendliness: LED lamps do not contain any heavy metal materials such as mercury, whereas fluorescent lamps do. This reflects the environmental friendliness of LED lamps. People now attach great importance to environmental protection, so more people are willing to choose environmentally friendly LED lamps. (4) Fast response speed is another prominent feature of LED lamps, meaning they react quickly. As soon as the power is connected, the LED lamp lights up immediately. Compared with the energy-saving lamps we usually use, their response speed is faster. When turning on traditional bulbs, it often takes a long time to illuminate the room, and they only light up after the bulb has thoroughly heated up. (5) Compared with other light sources, LED lamps are "cleaner." The term "clean" does not refer to the cleanliness of the lamp surface or interior, but rather that the lamp is a cold light source, does not generate excessive heat, and does not attract insects that are attracted to light and heat. Especially in summer, there are many insects in rural areas. Some insects are naturally heat-loving. Incandescent lamps and energy-saving lamps generate heat after being used for a period of time. This heat is exactly what insects like, making it easy to attract them. This will undoubtedly bring many pollutants to the lamp surface, and insect excrement will make the indoor environment dirty. However, LED lamps are cold light sources and do not attract insects, thus avoiding insect excrement. Therefore, LED lamps are "cleaner." Semiconductor light-emitting diodes have a wide range of applications, low power consumption, long service life, and are low-carbon and environmentally friendly. The application of semiconductor light-emitting diodes in China is very widespread. Many lighting devices in residential homes use semiconductor light-emitting diodes, and most streetlights use semiconductor light-emitting diode streetlights as the lighting source. Some road lighting fixtures also combine solar technology, saving a large amount of electrical energy. Photodiodes can be divided into gallium aluminum arsenide photodiodes, aluminum gallium phosphide arsenide photodiodes, gallium phosphide photodiodes, and aluminum arsenide photodiodes, depending on the material.
