The working principle of coils is based on the law of electromagnetic induction. When current passes through a coil, a magnetic field is generated around it; conversely, when the magnetic field changes, an induced current is generated in the wire. This principle is the basis of devices such as electric motors, generators, and transformers.
Inductance is the ability of a coil to store electrical energy, usually measured in Henry (H). The inductance value is related to the number of turns of the coil, the geometric shape of the coil, and the magnetic permeability of the material used.
DC resistance is the resistance value of the coil under direct current, usually measured in ohms (Ω). The DC resistance value affects the energy loss and heating of the coil.
The rated current is the maximum current that the coil can withstand under normal operating conditions, exceeding this value may cause the coil to overheat or damage.
The self-resonant frequency is the natural oscillation frequency of the coil under specific conditions, usually related to the inductance and capacitance values of the coil. The characteristics of self-resonant frequency are particularly important in wireless communication and signal processing.
An air core coil refers to a coil without a core, usually used in high-frequency applications, with low losses and good frequency response.
