bussmann electrical components Germany bussmann model bussmann price

bussmann electrical component is a photodetector that converts light into current or voltage signals depending on the application. The die typically uses a photosensitive PN junction, which is highly sensitive to changes in light, exhibits unidirectional conductivity, and changes its electrical characteristics with varying light intensity, allowing circuit current to be adjusted by light intensity. Photodiodes are also called photoelectric diodes. Photodiodes are structurally similar to semiconductor diodes; their die is a photosensitive PN junction with unidirectional conductivity, so a reverse voltage must be applied during operation. In the absence of light, there is a very small saturated reverse leakage current, known as dark current, at which point the photodiode is cut off. When exposed to light, the saturated reverse leakage current increases significantly, forming a photocurrent that varies with the intensity of incident light. When light irradiates the PN junction, it generates electron-hole pairs within the PN junction, increasing the density of minority carriers. These carriers drift under reverse voltage, causing the reverse current to increase. Therefore, the current in the circuit can be changed by varying the light intensity.

bussmann 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.

bussmann electrical component parameters

The main parameters of potentiometers include nominal resistance, rated power, resolution, sliding noise, resistance variation characteristic, 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 a 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%, and 1% depending on the precision class. The precision of precision potentiometers can reach 0.1%. 4. 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 unavailable during maintenance, a linear potentiometer may be used as a substitute, but a logarithmic one should not be used. Logarithmic potentiometers are only suitable for tone control, etc.

bussmann electrical component principle

Generators convert mechanical energy into electrical energy, and dry cells convert chemical energy into electrical energy. Generators and batteries themselves are not charged; their two poles have positive and negative charges respectively, generating voltage (current is formed by the directional movement of charges under the action of voltage). Charges are inherently present in conductors; to generate current, only voltage needs to be applied. When a conductor is connected to the two poles of a battery, positive and negative charges are released to generate current. When the charges are exhausted, the current (and voltage) disappears. Dry cells and the like are called power sources. A device that converts alternating current into direct current through transformers and rectifiers is called a rectified power supply. Electronic devices that provide signals are called signal sources. Crystal transistors can amplify incoming signals and transmit the amplified signals to subsequent circuits. For the subsequent circuit, a crystal transistor can also be regarded as a signal source. Rectified power supplies and signal sources are sometimes also referred to as power sources.
