KIRA LAMPS electrical components are energy conversion devices that convert DC electrical energy into AC electrical energy with a specific frequency; the circuit they form is called an oscillating circuit. Simply put, an oscillator is 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 to AC electrical energy can be called an "oscillator." Oscillators can be 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 power into AC 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. They are widely used in the electronics industry, medical care, scientific research, and other fields.

KIRA LAMPS electrical component parameters

1. Stable voltage refers to the stable voltage value generated across the terminals of a Zener diode when it passes the rated current. This value changes slightly with operating current and temperature. Due to differences in manufacturing processes, the stabilization voltage of Zener diodes of the same model is not completely consistent. 2. Reverse leakage current refers to the current passing through the Zener diode when it generates a stable voltage. Below this value, although the Zener diode can still stabilize voltage, the stabilization effect will deteriorate; above this value, as long as the rated power dissipation is not exceeded, it is permissible, and the stabilization performance will be better, but it will consume more electrical energy. 3. Dynamic resistance refers to the ratio of the change in voltage across the Zener diode to the change in current. This ratio changes with the operating current; generally, the larger the operating current, the smaller the dynamic resistance. 4. Rated power dissipation is determined by the allowable temperature rise of the chip, and its value is the product of the stable voltage and the maximum allowable current. 5. Temperature coefficient: If the temperature of the Zener diode changes, its stable voltage will also undergo slight changes. The relative change in voltage across the tube caused by a temperature change of 1℃ is the temperature coefficient (unit: %/℃). Generally speaking, stabilization voltages below 6V belong to Zener breakdown, where the temperature coefficient is negative; the temperature coefficient is positive. When the temperature rises, the depletion layer decreases. In the depletion layer, the valence electrons of atoms rise to higher energy levels, and a smaller electric field strength can excite valence electrons from the atoms to produce Zener breakdown, so its temperature coefficient is negative. Avalanche breakdown occurs when the depletion layer is wider and the electric field strength is lower. An increase in temperature increases the vibration amplitude of lattice atoms, hindering the movement of carriers. In this case, only by increasing the reverse voltage can avalanche breakdown occur, so the voltage temperature coefficient of avalanche breakdown is positive. For applications with high requirements for power supplies, two Zener diodes with opposite temperature coefficients can be connected in series for compensation. Due to mutual compensation, the temperature coefficient is greatly reduced. 11. Reverse leakage current refers to the leakage current generated by the Zener diode under the specified reverse voltage.

KIRA LAMPS electrical component classification

Self-inductance occurs when a current passes through a coil, generating a magnetic field around it. When the current in the coil changes, the surrounding magnetic field changes accordingly, and this changing magnetic field induces an electromotive force (induced EMF) in the coil itself (EMF is used to represent the terminal voltage of an ideal power source of an active component); this is self-inductance. An electronic component made by winding wire with a certain number of turns, capable of producing a certain amount of self-inductance or mutual inductance, is often called an inductor coil. To increase inductance, improve the quality factor, and reduce volume, a core made of ferromagnetic material, such as an iron core or magnetic core, is often added. The basic parameters of an inductor include inductance, quality factor, inherent capacitance, stability, current carrying capacity, and operating frequency. An inductor composed of a single coil is called a self-inductor, and its self-inductance is also known as the self-inductance coefficient. Mutual inductance occurs when two inductor coils are close to each other; the magnetic field change in one inductor coil affects the other. This influence is mutual inductance. The magnitude of mutual inductance depends on the self-inductance of the inductor coils and the degree of coupling between the two coils. Components manufactured using this principle are called mutual inductors.

(1) Nominal capacitance is the capacitance marked on the capacitor. However, there is a deviation between the actual capacitance and the nominal capacitance; the accuracy class corresponds to the permissible error. General capacitors commonly use classes I, II, and III, while electrolytic capacitors use classes IV, V, and VI to indicate capacitance accuracy, selected according to the application. The capacitance value of an electrolytic capacitor depends on the impedance presented during operation under AC voltage; the capacitance varies with changes in operating frequency, temperature, voltage, and measurement method. The unit of capacitance is F (farad). Since a capacitor is a "container" for storing electric charge, the issue of "capacity" size arises. To measure the ability of a capacitor to store electric charge, the physical quantity of capacitance is defined. A capacitor can only store electric charge under the action of an applied voltage. Different capacitors may store different amounts of charge under voltage action. It is internationally stipulated that when a DC voltage of 1 volts is applied to a capacitor, the amount of charge it can store is defined as the capacitance of that capacitor (i.e., the charge per unit voltage), represented by the letter C. The basic unit of capacitance is the farad (F). (2) Rated voltage is the maximum DC voltage that can be continuously applied to the capacitor at the minimum ambient temperature and the rated ambient temperature. If the operating voltage exceeds the voltage withstand capability of the capacitor, the capacitor will break down, causing damage. In practice, as the temperature rises, the voltage withstand value will decrease. (3) Insulation resistance. When DC voltage is applied to a capacitor, a leakage current is generated; the ratio of the two is called insulation resistance. When the capacitance is small, its value mainly depends on the surface condition of the capacitor; generally, the higher the insulation resistance, the better. (4) Loss. The energy consumed due to heating per unit time when a capacitor is under the action of an electric field is called loss. Loss is related to the frequency range, dielectric material, conductance, and the resistance of the metallic parts of the capacitor. (5) Frequency characteristics. As the frequency increases, the capacitance of general capacitors tends to decrease. When the capacitor operates below its resonant frequency, it exhibits capacitive behavior; when it exceeds its resonant frequency, it exhibits inductive behavior, at which point it is no longer a capacitor but an inductor. Therefore, it is essential to avoid operating the capacitor above its resonant frequency.
