The results are valid only for one layer, tightly wound, air core coils without gaps between the turns.
Number of coil turns : 3.0
Coil length : 10.000 mm (0.394 inches)
Coil diameter : 5.000 mm (0.197 inches)
Approximate inductance : 0.018443 µH
0.1% accurate inductance : 0.018170 µH
Methods of Increasing Inductor Q
- Use a larger diameter wire. This decreases the AC and DC resistance of the windings.
- Spread the windings apart. Air has a lower dielectric constant than most insulators. Thus, an air gap between the windings decreases the interwinding capacitance.
- Increase the permeability of the flux linkage path. This is most often done by winding the inductor around a magnetic core material, such as iron or ferrite. A coil made in this manner will also consist of fewer turns for a given inductance.
