The LG1 series inductors have an inductance range of 0.1~22000μH (marked on the housing). The LGA series inductors feature an ultra-small structure, resembling a 1/2W color band resistor in appearance, with an inductance range of 0.22~100μH (marked with color bands on the housing), and are micro inductors with a rated current of 0.09~0.4A. The LGX series color-coded inductors also have a small package structure, with an inductance range of 0.1~10000μH, and rated current options of 50mA, 150mA, 300mA, and 1.6A. Common adjustable inductors include oscillating coils for semiconductor radios, horizontal oscillating coils for TVs, linear horizontal coils, intermediate frequency band-stop coils, frequency compensation coils for audio equipment, and blocking coils, etc.


Inductors are typically composed of a frame, winding, shielding, encapsulation material, magnetic core, or iron core, etc. 1. Frame: The frame generally refers to the support for the winding. For larger fixed or adjustable inductors (such as oscillating coils, current-limiting coils, etc.), most are wound with enameled wire (or yarn-wrapped wire) around the frame, with the magnetic core, copper core, or iron core inserted into the inner cavity of the frame to increase the inductance. Frames are usually made of plastic, balsa wood, or ceramic and can be shaped according to specific needs. Small inductors (e.g., color code inductors) generally do not use a frame and instead directly wind the enameled wire around the magnetic core.


Wound from wire with a certain number of turns, these electronic components can produce a certain amount of self-inductance or mutual inductance and are commonly known as inductor coils. To increase the inductance value, improve the Q factor, and reduce the volume, surface mount inductors often incorporate an iron or ferrite core made from ferromagnetic materials. Basic parameters of inductors include inductance, quality factor, inherent capacitance, stability, current passing, and operating frequency. An inductor consisting of a single turn is called a self-inductor, with its self-inductance referred to as the self-inductance coefficient. When two inductor coils of a transformer are brought close together, the magnetic field change of one coil affects the other.
