Murrplastik electrical components Germany Murrplastik model Murrplastik price

Murrplastik electrical components are products whose raw material molecular composition is not changed during factory processing, and can be called components. Components belong to devices that do not require energy. They include: resistors, capacitors, and inductors. Circuit-type components include diodes and resistors; connection-type components include connectors, sockets, connecting cables, and printed circuit boards (PCB). Devices are products whose raw material molecular structure is changed during factory production and processing. Devices are divided into active devices and discrete devices. The main characteristic of active devices is that they generate or consume electrical energy and require an external power supply. Discrete devices are divided into bipolar junction transistors, field-effect transistors, thyristors, semiconductor resistors, and capacitors. shi

Murrplastik electrical component characteristics

Resolution refers to the ability of a sensor to detect the smallest change in the measured quantity. That is, if the input changes slowly from a non-zero value, the sensor output will not change when the input change does not exceed a certain value, meaning the sensor cannot resolve this change in the input. Only when the input change exceeds the resolution will the output change. Typically, the resolution at different points within the full-scale range of a sensor is not the same; therefore, the maximum change in input within the full scale that causes a step change in output is commonly used as the indicator for resolution. If the above indicator is expressed as a percentage of the full scale, it is called resolution. Resolution has a negative correlation with sensor stability.

Murrplastik electrical component applications

Light-emitting diodes are widely used in many fields. The following outlines their main applications: (1) Applications in consumer electronics: Light-emitting diodes are generally used as backlight sources for screens or for display and lighting purposes in electronic products. From large LCD TVs and computer monitors to media players MP3, MP4, and mobile phones, light-emitting diodes are used as screen backlights. (2) Applications in automobiles and heavy machinery: Light-emitting diodes are extensively used in automobiles and heavy machinery. Turn signals, interior lighting, instrument panel lighting, headlights, indicator lights, brake lights, and tail lights in automobiles and heavy mechanical equipment all utilize light-emitting diodes. This is mainly because light-emitting diodes offer fast response times and long service life (the lifespan of a light-emitting diode is generally longer than that of the automobile or heavy machinery itself). (3) Applications in coal mines: Due to characteristics such as high efficiency, low energy consumption, long lifespan, and high luminous intensity compared to conventional light-emitting devices, light-emitting diodes are used in miner's lamps and underground lighting equipment. Although not yet fully popularized, they will soon see widespread adoption, and light-emitting diodes will replace conventional light-emitting devices in coal mining applications. (7) Urban decorative lighting: In today's bustling commercial era, neon lights are an important symbol of urban vibrancy, but they have many drawbacks, such as insufficient lifespan. Therefore, replacing neon lights with light-emitting diodes offers many advantages. Compared to neon lights, light-emitting diodes not only have a longer lifespan but also feature energy savings, simple drive and control requirements, and maintenance-free operation. The replacement of neon lights by light-emitting diodes is an inevitable trend in the development of lighting equipment.

Murrplastik electrical component principles

A crystal diode is a p-n junction formed by p-type semiconductor and n-type semiconductor. A space charge layer is formed on both sides of its interface, establishing a built-in electric field. When no external voltage is applied, the diffusion current caused by the carrier concentration difference across the p-n junction and the drift current caused by the built-in electric field are equal, resulting in an electrical equilibrium state. When a forward bias voltage is applied externally, the mutual cancellation of the external electric field and the built-in electric field increases the carrier diffusion current, causing a forward current. When a reverse bias voltage is applied externally, the external electric field and the built-in electric field are further strengthened, forming a reverse saturation current within a certain reverse voltage range that is independent of the reverse bias voltage value. When the applied reverse voltage reaches a certain level, the electric field strength in the space charge layer of the p-n junction reaches a critical value, causing a carrier multiplication process. This generates a large number of electron-hole pairs, resulting in a significant reverse breakdown current, known as the diode breakdown phenomenon.
