SSIEDLESOHNE electrical components Germany SSIEDLESOHNE model SSIEDLESOHNE price

SSIEDLESOHNE electrical components consist of two conductors placed close to each other with a non-conductive insulating dielectric layer in between, forming a capacitor. When a 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 enclosed by another, or where all electric field lines originating from one conductor terminate on another conductor, is called a capacitor.

SSIEDLESOHNE electrical component operating principle

A DC power supply has positive and negative electrodes; the positive electrode has a higher potential, and the negative electrode has a lower potential. When the two electrodes are connected to a circuit, they maintain a constant potential difference across the circuit terminals, thereby forming a current from the positive to the negative electrode in the external circuit. Relying solely on the difference in water levels cannot maintain a steady water flow, but using a water pump to continuously move water from a lower level to a higher level can maintain a certain water level difference and form a steady water flow. Similarly, relying solely on the electrostatic field generated by electric charges cannot maintain a steady current. However, with a DC power supply, non-electrostatic forces (referred to as "non-electrostatic force") can be used to move positive charges from the negative electrode at a lower potential back to the positive electrode at a higher potential through the interior of the power supply, maintaining the potential difference between the two electrodes and thus forming a steady current. Therefore, a DC power supply is an energy conversion device that converts other forms of energy into electrical energy to supply the circuit, maintaining the steady flow of current.

SSIEDLESOHNE electrical component features

The main characteristics of thermistors are: (1) high sensitivity, with a resistance temperature coefficient larger than that of metals; (2) wide operating temperature range; (3) small size, capable of measuring temperatures in gaps, cavities, and blood vessels within living organisms that other thermometers cannot measure; (4) easy to use; (5) easy to process into complex shapes and suitable for mass production; (6) good stability and strong overload capacity.

SSIEDLESOHNE electrical component operating principle

1, emission of electrons from the emitter region to the base region: The power supply Ub is applied across the emitter junction via resistor Rb, forward-biasing the emitter junction. The majority carriers (free electrons) in the emitter region continuously cross the emitter junction into the base region, forming the emitter current Ie. At the same time, majority carriers in the base region also diffuse toward the emitter region, but since their concentration is far lower than that of the carriers in the emitter region, this current can be neglected; thus, the emitter junction current is considered primarily an electron flow. 2, diffusion and recombination of electrons in the base region: After entering the base region, electrons first accumulate near the emitter junction, gradually forming an electron concentration gradient. Under the influence of this concentration gradient, the electron flow diffuses through the base region toward the collector junction and is pulled into the collector region by the electric field of the collector junction, forming the collector current Ic. A very small portion of electrons (due to the thin base region) recombine with holes in the base region; the ratio of the diffusing electron flow to the recombining electron flow determines the amplification capability of the transistor. 13, collection of electrons by the collector region: Due to the large reverse voltage applied externally to the collector junction, the electric field force generated by this reverse voltage prevents electrons in the collector region from diffusing into the base region and simultaneously pulls electrons diffusing near the collector junction into the collector region, thereby forming the main collector current Icn. Additionally, minority carriers (holes) in the collector region undergo drift motion, flowing toward the base region to form a reverse saturation current, denoted by Icbo, which has a very small magnitude but is extremely sensitive to temperature.
