4.HA6.2000 electrical components are devices that convert other forms of energy into electrical energy and supply it to circuits (electronic devices). Power supplies operate on the principle of electromagnetic induction, generating electricity from renewable sources such as hydropower, wind power, tidal power, dam water pressure differences, and solar energy, as well as from burning coal and oil residue. A power supply is a device that delivers power to electronic equipment, also known as a power supply unit; it provides the electrical energy required by all components in a computer. The magnitude of the power supply's output, along with the stability of its current and voltage, directly affects the computer's performance and service life.

4.HA6.2000 electrical component composition

A two-terminal electronic component made of resistive material, with a specific structural form, that limits current flow in a circuit. Those with fixed resistance values are called fixed resistors. Those with variable resistance values are called potentiometers or variable resistors. An ideal resistor is linear, meaning the instantaneous current through the resistor is proportional to the applied instantaneous voltage. Some special resistors, such as thermistors, varistors, and sensitive elements, exhibit a non-linear relationship between voltage and current. Resistors are the most numerous components used in electronic circuits and are typically available in various series based on power rating and resistance value for selection by circuit designers. In circuits, resistors are mainly used to adjust and stabilize current and voltage; they can serve as shunts and voltage dividers, or as matched loads for circuits. Depending on circuit requirements, they can also be used for negative or positive feedback in amplifier circuits, voltage-to-current conversion, or as voltage/current protection elements during input overload. They can also form RC circuits to function as oscillation, filtering, bypass, differentiation, integration, and time constant elements.

4.HA6.2000 electrical component functions

The primary function of ferrite beads is to eliminate RF noise present in transmission line structures (circuits). RF energy consists of AC sinusoidal components superimposed on the DC transmission level, where the DC component is the desired useful signal. To eliminate this unwanted signal energy, chip ferrite beads act as high-frequency resistors (attenuators). Ferrite beads have high resistivity and permeability; they are equivalent to a resistor and an inductor in series, but both the resistance and inductance values vary with frequency. They offer better high-frequency filtering characteristics than ordinary inductors, exhibiting resistive behavior at high frequencies, which allows them to maintain high impedance over a relatively wide frequency range, thereby improving tuned filtering effects. Inductors can be used for power supply filtering. The circuit symbol for a ferrite bead is the same as that for an inductor, but the part number indicates the use of a ferrite bead. Functionally, ferrite beads and inductors operate on the same principle, differing only in their frequency characteristics. The DC component is the desired useful signal, whereas RF RF energy represents useless electromagnetic interference transmitted and radiated along the line. To eliminate this unwanted signal energy, chip ferrite beads act as high-frequency resistors (attenuators), allowing DC signals to pass while filtering out AC signals. Ferrite beads have high resistivity and permeability, equivalent to a resistor and an inductor in series. In a circuit, simply passing a wire through it suffices. High-frequency currents dissipate as heat within it; its equivalent circuit is an inductor and a resistor in series, with both component values proportional to the length of the ferrite bead. Some ferrite beads have multiple holes; passing a wire through them increases component impedance (proportional to the square of the number of passes through the bead). Ferrite beads can not only filter high-frequency noise in power supply circuits (suitable for both DC and AC outputs) but are also widely used in other circuits.

4.HA6.2000 electrical component structure

The main purpose of fiber optic connectors is to achieve fiber optic splicing. Fiber optic connectors, widely used in fiber optic communication systems, come in many types with diverse structures. However, upon closer examination, the basic structure of various fiber optic connector types is consistent: most generally use high-precision components (consisting of two ferrules and one coupling sleeve, totaling three parts) to achieve aligned fiber connections. This method involves inserting and fixing the fiber into the ferrule, polishing the ferrule surface, and achieving alignment within the coupling sleeve. The outer components of the ferrule are made of metal or non-metallic materials. The mating end of the ferrule must be ground, while the other end typically uses a strain relief boot to support the fiber or fiber optic cable to release stress. The coupling sleeve is generally made of two halves of ceramic or bronze, formed into a tight cylindrical component, often equipped with metal or plastic flanges to facilitate installation and fixation of the connector. To align the fibers as precisely as possible, the machining precision of the ferrule and coupling sleeve is required to be very high.
