Golden Eagle gives you a brief description of the magnetic tank inductor

Magnetic tank inductor is a common component in electronic circuit, which can realize power transmission, signal transmission and other functions. Its advantages are small size, light weight and low cost, stable performance and long service life. This paper will introduce the structure and principle of magnetic tank inductor in detail, and its application in the circuit.

Structure and principle The inductor coil of a magnetic tank is composed of a ferromagnetic core and a coil. Ferromagnetic cores are usually made of materials with high permeability, such as ferrite. A coil consists of thin wires wound around a ferromagnetic core. When a current passes through the coil, a magnetic field is generated, which magnetizes the core. The magnetization of the core creates a magnetic field, which affects the current in the coil. This interaction constitutes the working principle of magnetic tank inductors

The parameters of inductor in magnetic tank include inductance value, quality factor and resistance. Inductance is an important parameter of inductors, and the common unit is Henry (H). The quality factor refers to the quality factor of the inductor coil, and the larger the power loss of the coil, the smaller. Resistance is the ratio of current to voltage flowing through the coil, and its size depends on the resistance value and current size of the coil.

application

Magnetic tank inductors are widely used in electronic circuits. Here are a few examples

1. Filter: magnetic tank inductors can be used to construct low-pass filters and high-pass filters. The low-pass filter can remove high-frequency noise, and the high-pass filter can remove low-frequency clutter

2. Signal transmission: magnetic tank inductors can be used to adapt impedance to achieve signal transmission between different circuits. It can also be used to isolate different circuits from interfering with each other

3. Transformer: magnetic tank inductors can be used to construct transformers to achieve the transformation of electrical energy. The structure of transformer is relatively simple, stable performance, so it is widely used in power system.

4. Signal processor: magnetic tank inductors can be used to construct signal processors to realize signal amplification, filtering, mixing and other processing.

Magnetic tank inductor is a common component in electronic circuit, its structure and principle are relatively simple, widely used. In practical applications, it is necessary to choose the appropriate inductor according to the needs of the circuit, and pay attention to protecting the coil from electromagnetic interference.
