Micro-Hybrid electrical components Germany Micro-Hybrid model Micro-Hybrid price

Micro-Hybrid electrical component is a transducer that converts guided waves propagating on a transmission line into electromagnetic waves propagating in an unbounded medium (usually free space), or performs the reverse conversion. It is the component used in radio equipment to transmit or receive electromagnetic waves. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy, all of which use electromagnetic waves to transmit information, rely on antennas for operation. In addition, in terms of transmitting energy using electromagnetic waves, non-signal energy radiation also requires an antenna. Generally, antennas are reversible, meaning the same antenna can be used as both a transmitting antenna and a receiving antenna. The basic characteristic parameters of the same antenna for transmission or reception are identical. This is the reciprocity theorem of antennas. As we know, radio equipment such as communication, radar, navigation, broadcasting, and television devices all transmit information via radio waves and require the radiation and reception of radio waves. In radio equipment, the device used to radiate and receive radio waves is called an antenna. The antenna provides the necessary coupling between the transmitter or receiver and the medium through which radio waves propagate. Like the transmitter and receiver, the antenna is also an important component of radio equipment.

Common electrodynamic cone paper-cone loudspeaker. The electrodynamic cone loudspeaker, formerly known as the paper-cone loudspeaker, still primarily uses a paper cone for the diaphragm, but many polymer material diaphragms and metal diaphragms have also appeared, making the term cone loudspeaker more accurate. The cone paper-cone loudspeaker mainly consists of three parts: the magnetic circuit system (permanent magnet, core pole, magnetic plate), the vibration system (paper cone, voice coil), and the support auxiliary system (centering spider, basket, surround). 1. Voice coil: The voice coil is the drive unit of the cone paper-cone loudspeaker. It is made of very fine copper wire wound in two layers around a paper tube, generally with dozens of turns, also known as a coil, and is placed in the magnetic gap formed by the magnetic core pole and the magnetic plate. The voice coil is fixed to the paper cone; when an audio current signal is applied to the voice coil, the vibration of the voice coil drives the vibration of the paper cone. 2. Paper cone: There are many types of materials used for the conical diaphragm of cone paper-cone loudspeakers, generally divided into natural fibers and synthetic fibers. Natural fibers often include cotton, wood, wool, and silk, while synthetic fibers include rayon, nylon, and fiberglass. Since the paper cone is the sound-radiating element of the loudspeaker and largely determines its acoustic performance, any type of paper cone must be lightweight and rigid, and must not deform due to changes in ambient temperature or humidity. 3. Surround: The surround is designed to ensure the axial movement of the paper cone along the loudspeaker axis and restrict lateral movement, while also preventing air flow between the front and rear of the paper cone. In addition to materials commonly used for paper cones, the surround may use plastics, natural rubber, etc., which are thermally bonded to the paper cone. 8. Centering spider: The centering spider supports the junction of the voice coil and the paper cone, ensuring it remains vertical and not skewed. The centering spider has many concentric rings, allowing the voice coil to move freely up and down in the magnetic gap without lateral movement, ensuring the voice coil does not touch the magnetic plate. The dust cap on the centering spider prevents external dust from entering the magnetic gap, avoiding friction between dust and the voice coil that could cause abnormal sounds in the loudspeaker. A general loudspeaker consists of a magnet, frame, centering spider, molded surround, and cone paper cone.

Micro-Hybrid electrical component types

1, Classification by mounting type: Thermocouples are widely used as the primary temperature measurement method, so there are various requirements for their mounting devices and technical performance. Therefore, thermocouple mounting devices are divided into six types: no mounting device, threaded, fixed flange, movable flange, movable flange angle form, and tapered protection tube. 10, Classification by assembly and structural style: Based on the performance and structural style of thermocouples, they can be divided into detachable thermocouples, explosion-proof thermocouples, armored thermocouples, and spring-loaded fixed thermocouples for special applications.

Micro-Hybrid electrical component structure

Most people use unidirectional thyristors, commonly known as ordinary thyristors. They are composed of four layers of semiconductor materials and have three PN junctions, with three external electrodes: the electrode drawn from the first layer of P-type semiconductor is called the anode A, the electrode drawn from the third layer of P-type semiconductor is called the gate G, and the electrode drawn from the fourth layer of N-type semiconductor is called the cathode K. From the circuit symbol of the thyristor, it can be seen that, like a diode, it is a unidirectional conductive device, but with an additional gate G, which gives it operating characteristics completely different from those of a diode. The P1N1P2N2 four-layer, three-terminal device based on silicon monocrystal is internationally known as the silicon crystal thyristor, abbreviated as thyristor T, because its characteristics are similar to those of a vacuum thyratron. Since thyristors were initially used in static rectification, they are also called silicon controlled rectifiers, abbreviated as SCR SCR. In terms of performance, SCRs not only have unidirectional conductivity but also possess controllability that is more valuable than that of silicon rectifier elements (commonly known as "dead silicon"). They have only two states: conduction and blocking. SCRs can control high-power electromechanical equipment with milliampere-level currents. If this power is exceeded, the switching loss of the component increases significantly, and the allowable average current decreases; in this case, the rated current should be derated. SCRs have many advantages, such as controlling high power with low power, with power amplification factors reaching hundreds of thousands of times; extremely fast response, turning on and off within microseconds; contactless operation, no sparks, no noise; high efficiency, low cost, etc. Weaknesses of SCRs: poor static and dynamic overload capacity; prone to mis-triggering due to interference. SCRs are mainly classified by appearance into: bolt type, flat type, and flat-bottom type. Structure of SCR components. Regardless of the shape of the SCR, their chip cores are composed of four-layer P1N1P2N2 structures made of P-type silicon and N-type silicon. They have three PN junctions (J1, J2, J3), with the anode A drawn from the P1 layer of the J1 structure, the cathode K drawn from the N2 layer, and the gate G drawn from the P2 layer, making it a four-layer, three-terminal semiconductor device.
