Scanfil electrical components Germany Scanfil model Scanfil price

Scanfil electrical component is an energy conversion device that converts DC electrical energy into AC electrical energy with a specific frequency; the circuit it forms is called an oscillating circuit. An oscillator is simply a frequency source, generally used in phase-locked loops. In detail, it is a device that can convert DC electrical energy into AC electrical energy on its own without external signal excitation. It is generally divided into two types: positive feedback and negative resistance. The term "oscillation" implies AC; the oscillator includes the process and function of transitioning from non-oscillating to oscillating. Such a device capable of converting DC electrical energy into AC electrical energy is called an "oscillator." Oscillators are mainly divided into two types: harmonic oscillators and relaxation oscillators. They are electronic components used to generate repetitive electronic signals (usually sine waves or square waves). The circuit they form is called an oscillating circuit. It is an electronic circuit or device that can convert DC electricity into AC electrical signal output with a specific frequency. There are many types; classified by oscillation excitation method, they include self-excited oscillators and externally excited oscillators; classified by circuit structure, they include RC oscillators, LC oscillators, crystal oscillators, tuning fork oscillators, etc.; classified by output waveform, they include sine wave, square wave, and sawtooth wave oscillators. Widely used in the electronics industry, medical care, scientific research, and other aspects.

Scanfil electrical component classification

Classification by operating principle or structural characteristics of relays: (1) Electromagnetic relay: An electrical relay that operates using the attractive force generated between the electromagnet core and the armature by the current in the input circuit. (2) Solid-state relay: A relay where electronic components perform its functions without mechanical moving parts, providing isolation between input and output. (3) Temperature relay: A relay that operates when the ambient temperature reaches a set value. (4) Reed relay: A relay that opens, closes, or switches circuits using the action of reeds sealed in a tube, which serve the dual function of contact springs and armature magnetic circuit. (5) Time relay: A relay whose output section requires a delay or time limit to a specified time before closing or opening the controlled circuit when an input signal is applied or removed. (6) High-frequency relay: A relay used for switching high-frequency and RF lines with minimal loss. (7) Polarized relay: A relay that operates due to the combined effect of a polarizing magnetic field and the magnetic field generated by the control current passing through the control coil. The operating direction of the relay depends on the direction of the current flowing through the control coil. (8) Other types of relays: such as optical relays, acoustic relays, thermal relays, instrument relays, Hall effect relays, differential relays, etc.

Scanfil electrical component characteristics

Under normal circumstances, the actual static characteristic output of a sensor is a curve rather than a straight line. In practical work, 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 is 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 is used as the fitted straight line, known as the least squares fitted straight line.

Scanfil electrical component parameters

1. Nominal varistor voltage: The voltage value across the varistor when a pulse current of specified duration passes through it. 2. Voltage ratio: The ratio of the voltage value generated by the current of the varistor to the voltage value generated by the current of the varistor. 3. Maximum limiting voltage: The peak voltage across the varistor under the maximum pulse peak current Ip that the varistor can withstand and under a specified waveform. 4. Residual voltage ratio: When the current passing through the varistor is a certain value, the voltage generated across it is called the residual voltage for that current value. The residual voltage ratio is the ratio of the residual voltage to the nominal voltage. 5. Surge current capacity: Surge current capacity, also known as surge current, refers to the maximum pulse current value allowed to pass through the varistor under specified conditions. 6. Leakage current: Leakage current, also known as standby current, refers to the current flowing through the varistor at a specified temperature and maximum DC voltage. 7. Voltage temperature coefficient: Refers to the rate of change of the nominal voltage of the varistor within a specified temperature range, i.e., the relative change in voltage across the varistor when the temperature changes while the current passing through the varistor remains constant. 8. Current temperature coefficient: Refers to the relative change in current flowing through the varistor when the temperature changes while the voltage across the varistor remains constant. 9. Voltage non-linearity coefficient: Refers to the ratio of the static resistance value to the dynamic resistance value of the varistor under a given applied voltage. 10. Insulation resistance: Refers to the resistance value between the lead wires of the varistor and the insulating surface of the resistive body. 11. Static capacitance: Refers to the inherent capacitive capacity of the varistor itself. 12. Rated power: The maximum power at which the varistor operates at a specific ambient temperature causing a change in varistor voltage. 16. Maximum impulse current: The maximum impulse current that causes a change in varistor voltage when the varistor is subjected to a specific pulse current impact once or twice.
