Single-phase Inductor

Electronic components that are wound with wires, have a certain number of turns and can produce a certain amount of self-inductance or mutual inductance, are often called inductor coils. To increase the inductance value, improve the figure of merit, and reduce the volume, iron cores or magnetic cores made of ferromagnetic substances are often added. The basic parameters of an inductor include inductance, the figure of merit, intrinsic capacitance, stability, the current passing through, and frequency of use. An inductor composed of a single coil is called a Single-phase inductor, and its self-inductance is also called the self-inductance coefficient.

• The color ring inductor has a blocking effect: the copper core in the color ring inductor coil is always resistant to the current change in the coil. The color ring inductor has a hindering effect on the alternating current used in the circuit, and the size of the blocking effect is called inductive reactance XL, and the unit is ohms. Its relationship with the inductor L and the alternating current frequency f is XL=2πfL, and the color ring inductor can be mainly divided into high-frequency choke coils and low-frequency choke coils.
•  The color ring inductor has the function of tuning and frequency selection: the color ring inductor and the electrolytic capacitor can be connected in parallel to form an LC tuning circuit. The color ring inductance in the resonance of the circuit inductive reactance and capacitive reactance equivalent and reverse, that is, the inherent oscillation frequency of the circuit f0 and the frequency f of the non-AC signal is equal, then the inductive reactance and capacitive reactance of the circuit are also equal, the use of color ring inductance is generally not very high, the color ring inductor used in the circuit is generally relatively stable.
• The color ring inductor is mainly used to screen signals, filter noise, stabilize current, and suppress electromagnetic interference. The basic function of the color ring inductor is to charge and discharge, but many circuit phenomena extended by this basic charge and discharge effect make the color ring inductor have a variety of uses. Nowadays, the color ring inductor has been used by the majority of customers, but the role of a small inductor is not trivial.

Through DC: refers to the inductor to DC is closed state, if not counting the resistance of the inductor coil, then DC can pass through the inductor "unimpeded", for DC, the resistance of the coil itself is very small to the hindrance of DC, so it is often ignored in circuit analysis.

AC resistance: When the alternating current passes through the inductor coil, the inductor has an obstructive effect on the alternating current, and what hinders the alternating current is the inductive reactance of the inductor coil.
