cab 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.

cab electrical component classification

1, fuse resistors: also called fusible resistors, which act as both a resistor and a fuse under normal conditions. When a circuit fault causes power to exceed the rated power, it fuses like a fuse to disconnect the circuit. Fuse resistors generally have low resistance values and low power ratings. 9, sensitive resistors: refer to resistors whose resistance value is sensitive to certain physical quantities (such as temperature, humidity, light intensity, voltage, mechanical force, and gas concentration). When these physical quantities change, the resistance value of the sensitive resistor changes accordingly, presenting different resistance values. Based on sensitivity to different physical quantities, sensitive resistors can be classified into thermistors, humidity-sensitive resistors, photoresistors, varistors, force-sensitive resistors, magnetoresistors, and gas-sensitive resistors. The materials used for sensitive resistors are almost all semiconductor materials, so these resistors are also called semiconductor resistors. The resistance value of a thermistor changes with temperature; if the resistance decreases as temperature rises, it is a negative temperature coefficient (NTC) thermistor. NTC thermistors are widely used and can be further divided into general-purpose NTC thermistors, voltage-stabilizing NTC thermistors, and temperature-measuring NTC thermistors. A photoresistor's resistance value changes with the intensity of incident light; when incident light increases, the resistance of the photoresistor decreases, and when incident light weakens, the resistance value increases.

cab 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 used to connect component pins. ⑤ Connector: A component used for connections between printed circuit boards. ⑥ Copper pour: Copper filling applied to ground networks, which can effectively reduce impedance. ⑦ Electrical boundary: Used to define the dimensions of the printed circuit board; no components on the board may extend beyond this boundary.

cab electrical component principle

Potentiometric displacement sensors convert mechanical displacement into resistance or voltage output that has a linear or arbitrary functional relationship via potentiometer elements. Ordinary linear potentiometers and rotary potentiometers can be used as linear displacement and angular displacement sensors, respectively. However, potentiometers designed for displacement measurement require a definite relationship between displacement change and resistance change. The movable wiper of the potentiometric displacement sensor is connected to the measured object. The displacement of the object causes a resistance change at the moving end of the potentiometer. The magnitude of the resistance change reflects the magnitude of the displacement, while an increase or decrease in resistance indicates the direction of displacement. Typically, a supply voltage is applied to the potentiometer to convert the resistance change into a voltage output. In wire-wound potentiometers, the resistance changes in steps based on the turn-to-turn resistance as the wiper moves, resulting in a stepped output characteristic. If such a displacement sensor is used as a displacement feedback element in a servo system, excessive step voltage can cause system oscillation. Therefore, the resistance per turn should be minimized during potentiometer manufacturing. Another major disadvantage of potentiometric sensors is susceptibility to wear. Their advantages include simple structure, large output signal, ease of use, and low cost.
