EDDING electrical components Germany EDDING model EDDING price

EDDING electrical component is an electronic device with three terminals, made of three parts of semiconductors with different doping levels. The charge flow in the transistor is mainly due to the diffusion and drift movement of carriers at the PN junction. The operation of this transistor involves the flow of both electrons and holes, so it is called bipolar, also known as a bipolar junction transistor. This operating mode is different from unipolar transistors such as field-effect transistors, whose operation only involves the drift of one type of carrier. The boundary between the two regions with different dopant concentrations is formed by the PN junction. Bipolar transistors can amplify signals and have good power control, high-speed operation, and durability, so they are often used to form amplifier circuits or drive devices such as speakers and motors, and are widely used in aerospace engineering, medical devices, robotics, and other applications.

EDDING electrical component classification

Fiber optic connectors can be divided into common single-mode and multimode connectors for silica-based fibers based on the transmission medium, as well as other fiber optic connectors using plastic as the transmission medium. Based on the connector structure, they can be classified into: FC, SC, ST, LC, D4, DIN, MU, MT, and various other forms. Among them, ST connectors are typically used at the cabling equipment end, such as fiber patch panels and fiber modules; while SC and MT connectors are typically used at the network equipment end. Based on the fiber end-face shape, there are FC, PC (including SPC or UPC), and APC; based on the number of fiber cores, there are single-core and multi-core (such as MT-RJ) distinctions. Fiber optic connectors are widely used and come in many varieties. In practical applications, we generally distinguish them based on the different structures of the fiber optic connectors.

EDDING electrical component classification

Self-inductance occurs when a current passes through a coil, generating a magnetic field around it. When the current in the coil changes, the surrounding magnetic field also changes accordingly. This changing magnetic field induces an electromotive force (induced EMF) in the coil itself (EMF represents the terminal voltage of an ideal power source of an active component), which is self-inductance. An electronic component made by winding wire with a certain number of turns, capable of producing a certain amount of self-inductance or mutual inductance, is commonly called an inductor coil. To increase the inductance value, improve the quality factor, and reduce the size, a core made of ferromagnetic material, such as an iron core or magnetic core, is often added. The basic parameters of an inductor include inductance, quality factor, inherent capacitance, stability, current rating, and operating frequency. An inductor composed of a single coil is called a self-inductor, and its self-inductance is also known as the self-inductance coefficient. Mutual inductance occurs when two inductor coils are close to each other; a change in the magnetic field of one coil affects the other. This effect is called mutual inductance. The magnitude of mutual inductance depends on the self-inductance of the coils and the degree of coupling between them. Components manufactured using this principle are called mutual inductors.

EDDING electrical component features

A solid-state relay is a contactless electronic switch with isolation functionality. It has no mechanical contact parts during switching. Therefore, in addition to having the same functions as electromagnetic relays, solid-state relays are compatible with logic circuits, resistant to vibration and mechanical shock, have no restrictions on installation position, and offer good moisture, mold, and corrosion resistance. They also perform excellently in explosion-proof and ozone pollution prevention aspects. Features include low input power, high sensitivity, low control power, good electromagnetic compatibility, low noise, and high operating frequency. Solid-state relays have no internal mechanical parts and adopt a fully sealed potting structure, offering advantages such as vibration resistance, corrosion resistance, long life, and high reliability. AC solid-state relays use zero-crossing triggering technology, resulting in short switching times, making them suitable for higher frequency applications. Optical isolation is used between the input and output circuits, resulting in very low input power consumption. The output end has a protection circuit and strong load capacity.
