Inductor Coil Structure and Characteristics

Inductor coil Structure and Characteristics

The inductance coil is generally composed of a magnetic core or iron core, a skeleton, a winding group, a shielding cover, and packaging materials.


1. The skeleton generally refers to the stent on which the coil is wound. Some large fixed inductors or adjustable inductors (such as oscillating coils, choke coils, etc.), most of which are enameled wire (or yarn covered wire) directly wound on the skeleton, and then magnetic core or copper core, iron core Wait for the inner cavity of the skeleton to increase its inductance. The skeleton is usually made of plastic, bakelite, ceramic, and can be made into different shapes according to actual needs.


Small inductance coils (such as I-shaped inductors) generally do not use a skeleton, but directly wind the enameled wire on the magnetic core.


Air-core inductance coils (also called out-of-body coils or air-core coils, mostly used in high-frequency circuits) do not use magnetic cores, skeletons and shielding covers, etc., but are wound on the mold before removing the mold, and pulling between the coils Drive a certain distance.


2. Winding refers to a set of coils with prescribed functions, which are the basic components of inductance coils.


There are single-layer and multi-layer windings. There are two types of single-layer windings: close winding (the wires are wound next to each other) and indirect winding (the wires are separated by a certain distance when winding); the multilayer winding has layered flat winding and random winding. Winding, honeycomb winding and many other methods.


3. Magnetic cores and magnetic rods Magnetic cores and magnetic rods generally use nickel-zinc ferrite (NX series) or manganese-zinc ferrite (MX series) and other materials. It has "I" shape, cylindrical shape, cap shape, "E" shape, Various shapes such as pot shape and ring shape.


4. The core material mainly includes silicon steel sheet, permalloy, etc., and its shape is mostly "E" type.


5. In order to prevent the magnetic field generated by some inductive coils from affecting the normal operation of other circuits and components, the shielding cover is added with a metal screen cover (such as the oscillation coil of a semiconductor radio, etc.). The inductor with a shielding case will increase the loss of the coil and reduce the Q value.


6. Packaging materials

Some inductors (such as color code inductors, color ring inductors, etc.) are wound, and the coils and magnetic cores are sealed with packaging materials. The packaging material is plastic or epoxy resin.


Small fixed inductance coil

Small fixed inductance coils are usually made of enameled wire directly wound on the magnetic core. They are mainly used in circuits such as filtering, oscillation, trapping, delay, etc. It has two types of packaging, sealed and non-sealed, and both are available. There are two appearance structures, vertical and horizontal.


1.Vertical sealed fixed inductor

The vertical sealed fixed inductor adopts the same-directional pin. There are LG and LG2 series inductors made in China. The inductance range is 0.1~2200μH (directly marked on the shell), and the rated working current is 0.05 ~1.6A, the error range is ±5%~±10%. TDK series color code inductors are imported, and the inductance is marked on the surface of the inductor with color dots.


2. Horizontal sealed fixed inductors

Horizontal sealed fixed inductors use axial pins, and domestically produced LG1, LGA, LGX and other series.


The inductance range of LG1 series inductors is 0.1~22000μH (directly marked on the shell), the rated working current is 0.05~1.6A, and the error range is ±5%~±10%.


The LGA series inductors adopt an ultra-small structure, and the shape is similar to 1/2W color ring resistors. The inductance range is 0.22~100μH (marked on the shell with the color ring), and the rated current is 0.09~0.4A.


LGX series color code inductors also have a small package structure, with an inductance range of 0.1 ~ 10000μH, and the amount of current is divided into four specifications: 50mA, 150mA, 300mA and 1.6A.


3.Adjustable inductor

Commonly used adjustable inductors include oscillating coils for semiconductor radios, line oscillating coils for televisions, line linear coils, intermediate frequency trap coils, frequency compensation coils for audio, choke coils, etc.

The Role of Inductance Coil

Resistance, capacitance and inductance, they all present a certain resistance to the flow of electrical signals in the circuit. This resistance is called “impedance“. The impedance presented by the inductor to the current signal uses the self-inductance of the coil.

The Inductor Coil Manufacturer Briefly Describes the Performance Indicators of the Inductor Coil for You

The inductance of an inductor coil is a key performance index, determined by factors such as the number of turns, winding method, and presence of a magnetic core. The basic unit of inductance is Henry (H), with common units including millihenry (mH) and microhenry (μH). Inductance coils also exhibit inductive reactance and a quality factor (Q) related to their efficiency. Distributed capacitance and rated current are also important considerations.

Understanding Inductance Coils: Principles, Types and Selection

Inductance coil is a device that uses the principle of electromagnetic induction to work. When a current flows through a wire, a certain electromagnetic field will be generated around the wire, and the wire of this electromagnetic field will induce the wire within the range of this electromagnetic field.

Inductor and Transformer Testing Methods and Experience

This passage introduces methods for detecting color code inductors, mid-circle transformers, and power transformers. For color code inductors, use a multimeter to check resistance and identify faults. For mid-circle transformers, check winding connections and insulation. For power transformers, visually inspect, test insulation, check winding connections, identify primary and secondary coils, measure no-load current, detect no-load voltage, and identify short-circuit faults.

What are the Classifications of Commonly Used Inductance Coils?

Inductance coils, devices utilizing electromagnetic induction, are classified into various types. Based on inductance form, they are fixed and variable. By magnetic conductor, they are air core, ferrite, iron core, and copper core. By function, they include antenna, oscillating, choke, trap, and deflection coils. By winding structure, they are single-layer, multi-layer, honeycomb, etc.
