Choke coil: A choke coil is a toroidal magnetic core made of ferrite materia. When a high-frequency current passes through, it exhibits specific impedance characteristics. Its primary uses include suppressing electromagnetic interference (EMI) and signal filtering.

Inductor: An inductor is a passive component that suppresses current changes by storing energy in a magnetic field. It is typically constructed from a core (made of materials like ferrite or alloy powder) wound with insulated wire. In circuits, it serves functions such as filtering, oscillation, and energy buffering.

High-frequency transformer: This is a magnetic component operating on the principle of electromagnetic induction. Its working frequency typically exceeds 10 kHz (and can reach up to 1 MHz or higher). It is primarily used in high-frequency switching power supplies, inverter circuits, and energy conversion systems to achieve efficient power transmission and voltage transformation.
