DELTADORE electrical components Germany DELTADORE model DELTADORE price

DELTADORE electrical components are devices for detachable (active) connection between optical fibers. They precisely align the two end faces of the optical fibers to maximize the coupling of light energy output from the transmitting fiber into the receiving fiber, and minimize the impact on the system due to 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.

DELTADORE electrical components parameters

The main parameters of potentiometers include nominal resistance, rated power, resolution, sliding noise, resistance variation characteristics, wear resistance, zero-position resistance, and temperature coefficient. 1. Rated power: The maximum power allowed to be dissipated across the two fixed terminals of a potentiometer is its rated power. Note that the rated power is not equal to the power between the center tap and the fixed terminal. The rated power of a potentiometer refers to the maximum power allowed to be consumed under long-term continuous load at the specified rated temperature, when the atmospheric pressure is 87~107kPa. 2. Nominal resistance: The nominal resistance marked on the product, with series similar to those of resistors. 3. Tolerance class: The error range between the measured resistance and the nominal resistance allows for errors of 20%, 10%, 5%, 2%, 1% depending on the precision class. The precision of precision potentiometers can reach 0.1%. 12. Resistance variation law: Refers to the relationship between resistance and the rotation angle (or sliding travel) of the wiper contact. This relationship can take any functional form; common types include linear, logarithmic, and reverse logarithmic (exponential). In use, linear potentiometers are suitable as voltage dividers; reverse logarithmic (exponential) potentiometers are suitable as volume controls in radios, recorders, phonographs, and televisions. If a replacement of the same type is not available during maintenance, a linear type may be used as a substitute, but a logarithmic type is not recommended. Logarithmic potentiometers are only suitable for tone control, etc.

DELTADORE electrical components structure

The structure and materials of new high-voltage Schottky diodes differ from those of traditional Schottky diodes. Traditional Schottky diodes are formed by metal-semiconductor contact. Metals such as aluminum, gold, molybdenum, nickel, and titanium can be selected, while the semiconductor is typically silicon or gallium arsenide. Since electrons have higher mobility than holes, N-type semiconductor material is chosen as the substrate to achieve good frequency characteristics. To reduce the junction capacitance of the Schottky diode and increase the reverse breakdown voltage without causing excessive series resistance, a high-resistance N- thin layer is usually epitaxially grown on an N+ substrate. It is known that there are a large number of conductive electrons inside metal conductors. When metal contacts semiconductor (with the distance between them on the order of atomic size), the Fermi level of the metal is lower than that of the semiconductor. At the sub-levels corresponding to the conduction band of the semiconductor inside the metal, the electron density is lower than that in the conduction band of the semiconductor. Therefore, after contact, electrons diffuse from the semiconductor to the metal, causing the metal to become negatively charged and the semiconductor positively charged. Since metal is an ideal conductor, negative charge is distributed only within a thin layer on the surface with atomic-scale thickness. For N-type semiconductors, donor impurity atoms that lose electrons become positive ions and are distributed over a larger thickness. The result of electron diffusion from the semiconductor to the metal forms a space charge region, a built-in electric field, and a barrier, with the depletion layer located only on the N-type semiconductor side (the entire barrier region falls on the semiconductor side). The direction of the built-in electric field in the barrier region points from the N-type region to the metal. As thermionic emission increases the built-in field, the drift current opposite to the diffusion current increases, finally reaching dynamic equilibrium and forming a contact barrier between the metal and the semiconductor, known as the Schottky barrier. When the external voltage is zero, the electron diffusion current equals the reverse drift current, achieving dynamic equilibrium. When forward bias is applied (i.e., positive voltage to the metal, negative voltage to the semiconductor), the built-in field is weakened, the barrier on the semiconductor side is lowered, thus forming a forward current from the metal to the semiconductor. When reverse bias is applied, the built-in field is strengthened, the barrier height increases, forming a smaller reverse current from the semiconductor to the metal. Therefore, like SBD-PN junction diodes, it is a nonlinear device with unidirectional conductivity.
