choke coil transformer dip inductor choke coil filter inductor

Structural classification:

Air core inductor: No magnetic core, only wound by wire. Suitable for high-frequency applications.

Iron core inductor: Use ferromagnetic materials as magnetic core, such as ferrite, iron powder, etc. This type of inductor is usually used in low-frequency to medium-frequency applications.

Air core inductor: Use air as magnetic core, with good temperature stability, suitable for high-frequency applications.

Ferrite inductor: Use ferrite core, with high saturation flux density, suitable for high-frequency applications, especially in RF and communication fields.

Integrated inductor: Miniature inductor manufactured by integrated circuit technology, suitable for high-density circuit boards.

Application classification:

Power inductor: Used in power conversion circuits, such as switching power supplies, inverters, etc., capable of handling large currents.

Signal inductor: Used in signal processing circuits, such as filters, oscillators, etc., suitable for high-frequency signals.

Choke: Used to suppress high-frequency noise or prevent high-frequency signals from passing, usually used in RF circuits.

Coupled inductor: used for coupling between circuits, such as transformer primary and secondary coils.

Common mode inductor: used to suppress common mode noise, usually used for protection of power lines and data lines.
