MULTILENE electrical components Germany MULTILENE model MULTILENE price

MULTILENE electrical components is a general term for all single components based on semiconductor materials, including diodes, transistors, field-effect transistors, and thyristors made of various semiconductor materials (the latter three are all three-terminal devices). 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 oscillation. Transistors can be packaged individually or as part of an integrated circuit in a very small area that can accommodate one hundred million or more transistors.

MULTILENE electrical component principles

In power generation, transformation, transmission, distribution, and consumption lines, current magnitudes vary significantly, ranging from a few amperes to tens of thousands of amperes. To facilitate measurement, protection, and control, it is necessary to convert these to a relatively uniform current. Additionally, voltages on lines are generally high, making direct measurement very dangerous. Current transformers serve the function of current transformation and electrical isolation. For pointer-type ammeters, the secondary current of current transformers is mostly at the ampere level. For digital instruments, the sampled signal is generally at the milliampere level. The secondary current of miniature current transformers is at the milliampere level, primarily serving as a bridge between large transformers and sampling. Miniature current transformers are also referred to as "instrument current transformers." ("Instrument current transformer" implies precision current transformers with multiple current ratios used in laboratories, generally for extending instrument ranges.) Similar to transformers, current transformers operate based on the principle of electromagnetic induction; transformers transform voltage, whereas current transformers transform current. The winding connected to the measured current is called the primary winding; the winding connected to the measuring instrument is called the secondary winding. The ratio of the primary winding current I1 to the secondary winding I2 current is called the actual current ratio K. The current ratio when the current transformer operates at rated current is called the rated current ratio of the current transformer, denoted by Kn.

MULTILENE electrical component parameters

Important aspects of the optical parameters of LED include: luminous flux, luminous efficacy, luminous intensity, light intensity distribution, and wavelength. 1. Luminous efficacy is the ratio of luminous flux to electrical power, with the unit generally being lm/W. Luminous efficacy represents the energy-saving characteristics of a light source, which is an important indicator for measuring the performance of modern light sources. 2.LED Luminous intensity characterizes the strength of light emission in a specific direction. Since the light intensity of LED varies significantly at different spatial angles, we have studied the light intensity distribution characteristics of LED. This parameter has significant practical implications, directly affecting the minimum viewing angle of LED display devices. For example, for large color LED screens in stadiums, if the selected LED single-tube distribution range is very narrow, viewers at larger angles relative to the screen will see distorted images. Moreover, traffic sign lights require recognition by people over a wide range. 13. Regarding the spectral characteristics of LED, we mainly examine whether its monochromaticity is excellent, and pay attention to whether the main colors such as red, yellow, blue, green, and white LED are pure. Because in many occasions, such as traffic signals, strict requirements are placed on color. However, observations show that some LED signal lights in China emit blue-ish green and deep red. From this phenomenon, it is very necessary and meaningful to conduct specialized research on the spectral characteristics of LED.

MULTILENE 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 10 parts: the fuse element, the housing, and the support. Among these, 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 low melting points and fuse easily. Due to their higher resistivity, they are made with larger cross-sectional dimensions, 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 high melting points and do not fuse easily. However, due to their lower resistivity, they can be made with smaller cross-sectional dimensions 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 types. 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.
