SMD power inductor can be divided into the following types

SMD power inductor can be divided into the following types according to the working frequency:

high-frequency inductor,medium-frequency inductor and low-frequency inductor.

Generally speaking,air-core inductors, magnetic core inductors and copper core inductors are medium frequency or high frequency inductors, iron core inductors are mostly low frequency inductors.

If according to its application, SMD power inductors are be divided into the following types:

Oscillation inductance, Correction inductance, Kinescope deflection inductance, Choke inductance, Filter inductance, Isolation inductance, Compensated inductance,.

Among them,

Oscillation inductance is divided into TV line oscillation coil, east-west pincushion correction coil, etc.

Kinescope deflection inductors are divided into horizontal deflection coils and field deflection coils.

The choke inductors (also called choke coils) are divided into high-frequency choke coils, low-frequency choke coils, choke coils for electronic ballasts, TV line frequency choke coils, and TV airport frequency choke coils.

Filter inductance is divided into power supply (power frequency) filter inductance and high frequency filter inductance.
