What are the advantages and disadvantages of air core inductor?

Advantages:

There are some advantages of air core inductors which are given below.

• The air core inductor is cheap.
• The air core inductor is simple in construction.
• It has no core losses at high frequencies.
• The air core inductor does not depend upon the value of current it carries and also eliminates the iron losses from magnetic core.

Disadvantages:

There are some disadvantages of air core inductors which are given below.

• The number of turns in a coil necessary to achieve the same inductance that would occur in a solid-core inductor.
• The inductors of high inductance value are not possible.
• It is in large size.
• Its Q factor is low.
