106404 Electrical Component Applications

SMD inductors are electromagnetic induction components wound with insulated wire. They belong to commonly used inductor components. The function of SMD inductors: passing DC and blocking AC is a simple description; they isolate and filter AC signals, or form resonant circuits with capacitors, resistors, etc. Function of tuning and frequency selection inductors: an inductor coil connected in parallel with a capacitor can form an LC tuned circuit. Any current in the circuit through an SMD inductor generates a magnetic field, and the magnetic flux of this field acts on the circuit. When the current through the SMD inductor changes, the DC voltage potential generated in the SMD inductor will oppose the change in current. When the current through the inductor coil increases, the self-induced electromotive force generated by the inductor coil is opposite to the direction of the current, opposing the increase in current, while converting part of the electrical energy into magnetic energy stored in the inductor; when the current through the inductor coil decreases, the self-induced electromotive force is in the same direction as the current, opposing the decrease in current, while releasing the stored energy to compensate for the decrease in current. Therefore, after inductive filtering, not only are the ripple of the load current and voltage reduced and the waveform smoothed, but the conduction angle of the rectifier diode also increases. Inductor function 1: Color-ring inductors have a current-blocking effect: the copper core in the color-ring inductor coil always opposes changes in the current in the coil. Color-ring inductors impede the AC current used in the circuit; the magnitude of this impedance is called inductive reactance XL, measured in ohms. Its relationship with inductance L and AC frequency f is XL=2πfL. Color-ring inductors are mainly divided into high-frequency choke coils and low-frequency choke coils. Inductor function 2: Color-ring inductors have tuning and frequency selection functions: a color-ring inductor connected in parallel with an electrolytic capacitor can form an LC tuned circuit. At resonance, the inductive reactance and capacitive reactance of the circuit are equal in magnitude but opposite in direction, meaning the natural oscillation frequency f0 of the circuit equals the frequency f of the non-AC signal, so the inductive reactance and capacitive reactance of the loop are also equal. The usage of color-ring inductors is generally not very high, and color-ring inductors used in circuits are generally quite stable. Inductor function 7: The main uses of color-ring inductors are filtering signals, filtering noise, stabilizing current, and suppressing electromagnetic interference. The basic function of color-ring inductors is charging and discharging, but many circuit phenomena derived from this basic charging and discharging function give color-ring inductors various different applications. Today, color-ring inductors are widely used by customers, and the role played by these small inductors should not be underestimated.

106404 Electrical Component Functions

The main functions of potentiometers in circuits include several aspects: 1. Used as a voltage divider. A potentiometer is a continuously adjustable resistor. When adjusting the knob or slider of the potentiometer, the moving contact slides on the resistive element. At this time, a output voltage related to the external voltage applied to the potentiometer and the angle or travel of the movable arm can be obtained at the output terminal of the potentiometer. 2. Used as a rheostat. When a potentiometer is used as a rheostat, it should be connected as a two-terminal device, so that a smoothly and continuously changing resistance value can be obtained within the travel range of the potentiometer. 4. Used as a current controller. When a potentiometer is used as a current controller, one of the selected current output terminals must be the terminal led out from the sliding contact.

106404 Electrical Component Composition

A multimeter consists of three main components: the meter head, the measurement circuit, and the selector switch. It is the most basic tool in the field of electronic testing and a widely used test instrument. A multimeter is also called a multi-meter, a triple-purpose meter (A, V, Ω, i.e., for current, voltage, and resistance), a multiplexing meter, or a universal meter. Multimeters are divided into analog (pointer-type) multimeters and digital multimeters. There is also an oscilloscope multimeter with oscilloscope functionality, which is a multi-function, multi-range measuring instrument. General multimeters can measure DC current, DC voltage, AC voltage, resistance, and audio levels; some models can also measure AC current, capacitance, inductance, temperature, and certain parameters of semiconductors (diodes, transistors). Digital multimeters have become the mainstream and have replaced analog instruments. Compared with analog instruments, digital instruments offer higher sensitivity, higher accuracy, clearer displays, stronger overload capacity, and are easier to carry and simpler to use.
