Inductor

Inductor is a kind of electromagnetic induction element, which is made of insulated wire winding bracket (bobbin) or iron core (core) and wound with a certain number of turns of coil (coil), and the principle is to use the principle of electromagnetic induction to work, When current flows through a wire, a certain electromagnetic field will be generated around the wire, and the electromagnetic field itself will induce induction on the wire within the range of the electromagnetic field, referred to as L, and the unit is Henry (H), millihenry (mH), Micro Henry (uH)

Inductors can be classified into different types according to their structure, application and characteristics. The following are some common types of inductors:

Coil inductance (Air Core Inductor): This is the most basic type of inductance. It is composed of a coil of conductor and is usually not filled with magnetic materials. Coil inductors are often used in high-frequency applications, such as wireless communication and broadcast frequency ranges, because the absence of magnetic materials reduces the loss of magnetic materials to high-frequency signals.

Iron Core Inductor: This inductor contains a core of magnetic material, usually iron or another magnetic alloy, around a coil of conductor. Iron core inductors have higher inductance and self-inductance, so they are more common in low frequency and high current applications. They are commonly used in equipment such as transformers, AC motors, and power filters.

Multilayer Inductor: This inductor has multiple layers of conductor coils stacked together to save space and achieve higher inductive capabilities. Multilayer inductors are commonly used in integrated circuits (ICs) and small electronic devices such as cell phones and tablets.

Polymer Bead Inductor: Polymer Bead Inductor is a special kind of inductor, usually used in high frequency filtering applications, such as on cables, data lines and power lines. Their housings are made of magnetic materials such as ferrite, which effectively suppress high-frequency noise and EMI (electromagnetic interference).

Variable Inductor: The inductance value of this inductance can be adjusted by mechanical or electrical means. Variable inductors are commonly found in wireless communications and tuning applications, where they can be used to adjust the frequency response or gain of a circuit.

High-Frequency Inductor: This inductor is specially designed for high-frequency applications, and usually has special structures and materials to meet the needs of high-frequency environments. High-frequency inductors are commonly found in RF transceivers, microwave circuits, and radar systems.

Autonomous Oscillating Inductor (Autotransformer): This is a special inductor with a common coil of conductors for input and output. Autonomous oscillator inductors are commonly used in converters and oscillators for AC power supplies.
