SEG electrical components Germany SEG model SEG price

SEG electrical components consist of two conductors placed close to each other with a layer of non-conductive insulating medium in between, forming a capacitor. When voltage is applied across the two plates of the capacitor, it stores charge. The capacitance value is numerically equal to the ratio of the charge on one conductive plate to the voltage between the two plates. The basic unit of capacitance is the Farad (F). In circuit diagrams, the letter C is commonly used to represent capacitive elements; capacitors are components that store electric charge and electrical energy (electric potential energy). A system of conductors where one conductor is surrounded by another, or where all electric field lines originating from one conductor terminate on another conductor, is called a capacitor.

SEG electrical component functions

The main functions of potentiometers in circuits include: 1. Used as a voltage divider. A potentiometer is a continuously adjustable resistor. When the knob or slider is adjusted, the movable contact slides along the resistive element. At this time, the output terminal of the potentiometer provides an output voltage that has a specific relationship with the applied voltage and the angle or travel of the movable arm. 2. Used as a rheostat. When a potentiometer is used as a rheostat, it should be connected as a two-terminal device, allowing a smoothly and continuously changing resistance value to be obtained within the travel range of the potentiometer. 13. Used as a current controller. When a potentiometer is used as a current controller, one of the selected current output terminals must be the terminal connected to the sliding contact.

SEG electrical component principle

The absorption film irradiated by infrared rays is a thin film with low heat capacity and easy temperature rise. A cavity structure is located at the bottom near the center of the substrate. This design ensures a temperature difference between the cold junction and the measuring junction. The thermocouple is composed of polysilicon and aluminum, connected in series. When the temperature at the measuring junctions of the thermocouples rises, a thermoelectromotive force Vn is generated between the thermocouples, so the sum of their voltages can be obtained at the output terminal.

SEG electrical component composition

A two-terminal electronic component made of resistive material, with a specific structural form, capable of limiting current flow in a circuit. Those with unchangeable resistance values are called fixed resistors. Those with variable resistance values are called potentiometers or variable resistors. An ideal resistor is linear, meaning the instantaneous current through the resistor is proportional to the applied instantaneous voltage. Some special resistors, such as thermistors, varistors, and sensitive elements, have a non-linear relationship between voltage and current. Resistors are the most widely used components in electronic circuits, typically available in various series based on power and resistance values for selection by circuit designers. In circuits, resistors are mainly used to adjust and stabilize current and voltage, serving as shunts and voltage dividers, and also as matching loads. Depending on circuit requirements, they can also be used for negative or positive feedback in amplifier circuits, voltage-to-current conversion, voltage or current protection during input overload, and can form RC circuits to serve as oscillation, filtering, bypass, differentiation, integration, and time constant elements.
