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; an oscillator includes the process and function of transitioning from non-oscillating to oscillating. Devices capable of completing the conversion from DC electrical energy to AC electrical energy can be called "oscillators." 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 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, sawtooth wave oscillators, etc. Widely used in the electronics industry, medical care, scientific research, and other aspects.

KIRA LAMPS electrical component parameters

1. Stable voltage refers to the stable voltage value generated across the terminals when the Zener diode passes the rated current. This value changes slightly with different operating currents and temperatures. 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 value 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 voltage change to the current change across the Zener diode terminals. This ratio changes with different operating currents; 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 terminals 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 out of 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 the coil. When the current in the coil changes, the surrounding magnetic field also changes correspondingly. 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), which is self-inductance. Electronic components made by winding wires with a certain number of turns, capable of producing a certain amount of self-inductance or mutual inductance, are often called inductor coils. To increase inductance, improve the quality factor, and reduce volume, iron cores or magnetic cores made of ferromagnetic materials are often added. Basic parameters of inductors include inductance, quality factor, inherent capacitance, stability, current carrying capacity, and operating frequency. Inductors composed of a single coil are called self-inductors, and their 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 of the capacitor and the nominal capacitance; the precision grade corresponds to the allowable error. General capacitors commonly use grades I, II, and III, while electrolytic capacitors use grades IV, V, and VI to indicate capacitance precision, selected according to application. The capacitance value of electrolytic capacitors depends on the impedance presented during operation under AC voltage. The capacitance value changes with operating frequency, temperature, voltage, and measurement methods. The unit of capacitance is F (Farad). Since a capacitor is a "container" for storing charge, there is the issue of "capacity" size. To measure the ability of a capacitor to store charge, the physical quantity of capacitance is defined. Capacitors can only store charge under the action of an applied voltage. Different capacitors may store different amounts of charge under voltage action. Internationally, it is uniformly stipulated that when a DC voltage of 1 volts is applied to a capacitor, the amount of charge it can store is 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 and rated ambient temperatures. If the operating voltage exceeds the withstand voltage of the capacitor, the capacitor will break down, causing damage. In practice, as the temperature rises, the withstand voltage will decrease. (3) Insulation resistance. When DC voltage is applied to a capacitor, 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 state of the capacitor. Generally, the larger the insulation resistance, the better. (4) Loss. The energy consumed by heat generation per unit time under the action of an electric field is called loss. Loss is related to frequency range, dielectric material, conductivity, and the resistance of the metal parts of the capacitor. (5) Frequency characteristics. As 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 capacitors above their resonant frequency.
