What the characteristics of single layer coil inductor?

The single layer coil is wound around the coil or the bakelite skeleton by insulated wires, such as the antenna coil in the transistor radio.

The inductance of the single layer coil is small, which is like several microtens to tens of microhenry.

Single-layer coils are usually used in high frequency circuits. In order to improve the Q value of the coil, the skeleton of a single coil often uses ceramics and polystyrene materials with small dielectric loss. 

The winding of the coil can be coiled and wound around. There is a certain distance between each coil of the coil, so the distributed capacitance is small. High Q value and high stability can be obtained when the thick wire is used. However, the inductance of the coil winding can not be very large, so it can be used in the situation where the distribution capacitance is small, the stability is high, and the inductance is small.

For the coil with an inductance greater than 15H, the coil can be densely wound. The volume of the coiled coil is small, but the capacitance between the coils is large, so that the Q value and the stability are reduced. In addition, for some occasions requiring high stability, silver plating is also applied to the surface of porcelain skeleton with a small expansion coefficient, a high stable coil with very small inductance. In the case of high frequency and high current,the coil is usually wound by copper tube.
