Types of inductor Of Electronic Components
- The following are the types of inductors:
- Air core inductor,
- Ferromagnetic core inductor,
- variable inductor
- Air core inductor: It is an inductor which has its coil wound on nonmagnetic material like plastic
or ceramic and there is only air present in between the windings.
- Ferromagnetic inductor: It is an inductor which has its coil wound on a magnetic core made up of ferromagnetic or ferromagnetic material.
Laminated core: It is a type of ferromagnetic inductor whose core is made up of thin steel
sheets or laminations.
Ferrite core: It is a type of ferromagnetic inductor whose core is made up of ferrite.
Torroidal core: It is a type of ferromagnetic inductor where the coil is wound on a straight rod
shaped core.
Choke: It consist of a coil of insulating material wound on a magnetic material.
- Variable inductor: It is made up of ferrite magnetic core which can be slid or screwed to change
inductance.
Features of inductor:-
- All inductors are magnetic materials.
- They have a path of ferromagnetic material.
- The path is closed so that the magnetic field lies in the ferromagnetic material.
Specifications:-
- The value of inductance is measured in Henry. Inductive tolerance is usually in the range of 5% to +20%.
- Maximum current rating which specifies the maximum current that can pass through the coil.
