Do you know the seven commonly used coils?

1.Copper core coil
Copper core coils are used in ultra-short wave scales, and the inductance is changed by the orientation of the rotating copper core in the coil. This adjustment is convenient and useful.
2. Color code inductor
A color code inductor is an inductor with a fixed inductance. The inductance is marked with a color ring like a resistor.
3. Choke ring
The coil that constrains the passage of alternating current is called a choke, and is divided into a high-frequency choke coil and a low-frequency choke coil.
4. Deflection coil
The deflection yoke is the load of the output stage of the TV scanning circuit. The deflection yoke requires high deflection sensitivity, uniform magnetic field, high Q value, small size and low quotation.
5.Single layer coil
The single-layer coil is wound around the paper tube or bakelite skeleton in a circle with insulated wires. Such as a transistor radio wave antenna coil.
6. Honeycomb coil
If the coil is wound, its plane is not parallel to the plane of rotation, but intersects to a certain point of view. This type of coil is called a honeycomb coil. And the number of times the wire is bent back and forth, often referred to as the number of vertices. The advantages of the honeycomb type winding method are small size, small distributed capacitance, and large inductance. The honeycomb coils are wound by the honeycomb winding machine. The more the folding points, the smaller the distributed capacitance.
7. Ferrite core and iron powder core coil
The inductance of the coil is related to the presence or absence of a magnetic core. Piercing the ferrite core in the air core coil increases the inductance and the quality factor of the forward coil.
