NH00 electrical components are switches controlled by electromagnets, i.e., a combination of an electromagnet and a switch. When the electromagnet coil is energized, it generates electromagnetic attraction, causing the movable iron core to push or pull the switch contacts to close, thereby connecting the controlled circuit. Electromagnetic switches are widely used in various industries, most commonly as contactors in the industrial sector. An electromagnetic switch is the control switch on a starter motor and is one of the three main components of a starter (DC motor, transmission engagement mechanism, electromagnetic switch). Its working principle is that when the coil is energized, it generates electromagnetic attraction, causing the movable iron core to move. This simultaneously pulls the transmission engagement mechanism to advance the starter pinion gear into mesh with the engine flywheel ring gear, and pushes the switch contacts to connect, powering the DC motor to operate and thus driving the engine to start.

NH00 electrical component principle

A varactor diode is a type of special diode. When a forward bias is applied, a large current flows, the PN (positive-negative) junction depletion region narrows, capacitance increases, and a diffusion capacitance effect is produced; when a reverse bias is applied, a transition capacitance effect is produced. However, since leakage current occurs under forward bias, reverse bias is typically applied in applications. A varactor diode, also known as a voltage-controlled variable capacitor, is a semiconductor that changes its junction capacitance according to the applied voltage variation. In other words, as a variable capacitor, it can be applied in resonant circuits such as FM tuners and TV tuners, as well as in FM modulation circuits. Essentially, it can be viewed as a PN junction. If a reverse voltage V is applied across the PN junction (since varactor diodes are used in reverse), electrons in the N-type semiconductor are attracted to the positive electrode, and holes in the P-type semiconductor are attracted to the negative electrode, forming a depletion layer devoid of both electrons and holes. The width of this depletion layer is denoted as d, which varies with the reverse voltage V. Thus, as the reverse voltage V increases, the depletion layer d widens, and the diode's capacitance C decreases (according to C=kS/d); conversely, as the reverse voltage decreases, the depletion layer width d narrows, and the diode's capacitance increases. Changes in the reverse voltage V cause changes in the depletion layer, thereby altering the junction capacitance C of the voltage-controlled variable capacitor, achieving the desired effect. Varactor diodes are semiconductor devices manufactured based on the principle of variable capacitance across the PN junction, serving as variable capacitors in high-frequency tuning, communication, and other circuits. Varactor diodes come in various package types, including glass encapsulation (glass-sealed), plastic encapsulation (plastic-sealed), metal casing encapsulation (metal-sealed), and leadless surface mount packages. Typically, low-to-medium power varactor diodes use glass, plastic, or surface mount packages, while higher power varactor diodes mostly use metal seals. Common varactor diode parameters.
