There are many types of inductive coils, and the following is a brief introduction to several common types of inductive coils:
1. Single layer coil: A single layer coil is made by winding insulated wires one by one on a paper tube or a gluewood frame. Like a transistor radio medium wave antenna coil.
2. If a honeycomb coil is wound on a plane that is not parallel to the rotating surface but intersects at a certain angle, it is called a honeycomb coil. And the number of times the wire bends back and forth after one revolution is often referred to as the number of bends. The advantages of honeycomb winding method are small volume, small distributed capacitance, and large inductance. Honeycomb coils are all wound using a honeycomb winding machine, with more folding points and smaller distributed capacitance.
3. The inductance of the ferrite core and iron powder core coil is related to the presence or absence of a magnetic core. Inserting a ferrite core into an empty core coil can increase the inductance and improve the quality factor of the coil.
4. Copper core coils are widely used in the ultra short wave range. By rotating the position of the copper core in the coil to change the inductance, this adjustment is more convenient and durable.
5. Color code inductor is an inductor with a fixed inductance, and its inductance is marked with a color ring like a resistor.
6. Choke coils (choke coils) are coils that restrict the passage of alternating current, and are divided into high-frequency choke coils and low-frequency choke coils.
7. A deflection coil is a load on the output stage of a television scanning circuit. The deflection coil requires high deflection sensitivity, uniform magnetic field, high Q value, and small volume.
