attema electrical components Germany attema model attema price

attema electrical components are Schottky barrier diodes named after their inventor, Dr. Schottky. Schottky barrier diodes are not made using the principle of forming a PN junction by contact between P-type semiconductor and N-type semiconductor, but rather using the principle of a metal-semiconductor junction formed by contact between metal and semiconductor. Therefore, Schottky barrier diodes are also called metal-semiconductor (contact) diodes or surface barrier diodes; they are a type of hot-carrier diode.

attema electrical component parameters

Rated voltage: refers to the safe voltage allowed during normal operation of the switch. If the voltage applied across the switch exceeds this value, arcing and breakdown will occur between the two contacts. Rated current: refers to the maximum safe current allowed to pass when the switch is closed; if this value is exceeded, the switch contacts will burn out due to excessive current. Insulation resistance: refers to the resistance value between the conductive part and the insulating part of the switch. Contact resistance: refers to the resistance value between each pair of contacts when the switch is in the on state. Dielectric strength: refers to the maximum voltage the switch can withstand between the conductor and ground. Service life: refers to the number of operations the switch can perform under normal working conditions.

attema electrical component characteristics

Under normal circumstances, the actual static characteristic output of a sensor is a curve rather than a straight line. In practical applications, to enable instruments to have uniformly scaled readings, a fitted straight line is often used to approximately represent the actual characteristic curve. Linearity (non-linear error) is a performance indicator of this degree of approximation. There are various methods for selecting the fitted straight line. For example, the theoretical straight line connecting the zero-input and full-scale output points can be used as the fitted straight line; or the theoretical straight line that minimizes the sum of squared deviations from each point on the characteristic curve can be used as the fitted straight line, which is called the least-squares fitted straight line.

attema electrical component composition

The printed circuit board mainly consists of pads, vias, mounting holes, traces, components, connectors, copper pours, and electrical boundaries. ① Pad: A metal hole used for soldering component pins. ② Via: Includes metallic vias and non-metallic vias; metallic vias are used to connect component pins between layers. ③ Mounting hole: Used to secure the printed circuit board. ④ Trace: Copper film forming an electrical network to connect component pins. ⑤ Connector: A component used for connections between printed circuit boards. ⑥ Copper pour: Copper filling for the ground network, which can effectively reduce impedance. ⑦ Electrical boundary: Defines the dimensions of the printed circuit board; no components on the board may extend beyond this boundary.
