An inductor is basically a coil of wire.A inductor or a coil is an electrical component. Which is with manufactured a specified amount of inductance. The inductors are used in tuning and filter circuit.
They are in radio receivers as used in radio receivers as a built in antenna coil to pick up radio signals. The inductors are of two types namely fixed inductors and variable inductor depending upon the types of core, whether it is fixed or variable. They are suitable for radio frequency application. Is laminated to avoid eddy-currents los fig. A ferrite is a magnetic consisting of fine particle of iron cobalt or nickel or embedded in an insulator binder.
But the core is adjustable. The variable inductors are use in tuning and filter circuit. In case of large inductance coils a variable inductor is made of a long coil wound on a ferrite—core provide contact. The slider contact can be used to vary the inductance of a coil. We know that a pure or intrinsic semiconductor has no free charge carriers at absolute zero 00k temperature. Read More. Are you a beginner in Electronics wondering where to start?

Depending on their material type they are basically categorized as follows. Ceramic is the most commonly used material for inductor cores. Since ceramic has no magnetic properties, there is no increase in the permeability value due to the core material. Its main aim is to give a form for the coil. In some cases it will also provide the structure to hold the terminals in place.
The main advantage of these inductors are very low core losses, high Quality factor. These are mainly used in high frequency applications where low inductance values are required. Back to top. In the areas where low space inductors are in need then these iron core inductors are best option.
These inductors have high power and high inductance value but limited in high frequency capacity. These are applicable in audio equipments. When compared with other core indictors these have very limited applications. Ferrite is also referred as ferromagnetic material. They exhibit magnetic properties. They consist of mixed metal oxide of iron and other elements to form crystalline structures. The general composition of ferrites is XFe 2 O 4. Where X represents transition materials.
Mostly easily magnetized material combinations are used such as manganese and zinc MnZnnickel and zinc niZn. Ferrites are mainly two types they are soft ferrites and hard ferrites. These are classified according to the magnetic coercivity. Coercivity is the magnetic field intensity needed to demagnetize the ferromagnetic material from complete saturation state to zero. Soft Ferrite These materials will have the ability to reverse their polarity of their magnetization without any particular amount of energy needed to reverse the magnetic polarity.
These are also called as permanent magnets.PASSIVE COMPONENTS - INDUCTORS - TYPES
These will keep the polarity of the magnetization even after removing the magnetic field. Ferrite core inductor will help to improve the performance of the inductor by increasing the permeability of the coil which leads to increase the value of the inductance.
The level of the permeability of the ferrite core used within the inductors will depend on the ferrite material. This permeability level ranges from 20 to 15, according to the material of ferrite.
Thus the inductance is very high with ferrite core when compared to the inductor with air core. These are formed from very fine particles with insulated particles of highly pure iron powder.
It gives us a solid looking core when this iron power is compressed under very high pressure and mixed with a binder such as epoxy or phenolic.An inductor is a device that temporarily stores electrical energy in the form of a magnetic field. Physically, they are essentially electrical conductors — such as wire — wound into a coil. When electricity flows through the coil, a magnetic field is generated around the wire in a direction related to the flow of current in accordance with the laws of electromagnetic induction.
When the current is switched on, the magnetic field expands until it stabilizes, resulting in an accumulation of stored electrical energy. When the flow of current ceases, the magnetic field generated in the inductor continues to supply current to the circuit, converting magnetic energy into mechanical energy until the field collapses. In some ways inductors are similar to capacitors, except they store energy in the form of a magnetic field instead of a static charge, and they resist sudden changes in current as opposed to voltage.
MPS Industries, Inc. Fixed inductors are defined as inductors with a static, unchangeable inductance value. Some of the custom fixed inductors we manufacture include:. The variability in the construction and configuration of our inductors make them suitable for a wide range of applications such as:.
Filters When used with capacitors and resistors, inductors can be used to create filters. These electronic devices are essential in signal processing and are used to limit the frequency of input signals entering a circuit. Low pass, high pass, and band filters are just some of the filters designed with inductors.
Sensors Inductors can be used in proximity sensors that work based on the principle of electromagnetic inductance. They operate by sensing the presence of a magnetic field or magnetically permeable materials. Inductive sensors can commonly be found in traffic lights to detect traffic density.
Transformers Inductors are integral to the operation of transformers. By combining more than one inductor with a shared magnetic path, varying primary and secondary coils can be used to step up or step down voltages to desired levels.
Tuned circuits Tuned circuits can either be constructed from inductors in series or inductors in parallel together with a capacitor. These circuits are used to select the desired frequency in devices such as televisions, radios, and other tuning devices. Motors An induction motor operates by utilizing an applied magnetic force caused by the flow of alternating current to convert electrical energy to mechanical energy.
Inductors used in this application may also be connected in series or parallel. Energy storage devices Similar to capacitors, inductors can also be used for the storage of electrical energy for a limited time.Definition: The inductor is a passive component which stores the electrical energy in the magnetic field when the electric current passes through it.
Or we can say that the inductor is an electrical device which possesses the inductance. The inductor is made of wire which has the property of inductance, i. The inductance of wire increases by increasing the number of turns.
The inductance characterises the inductor. The figure below shows the symbolic representation of inductor. The electric current I flows through the coil generates the magnetic field around it. The ratio of the flux and the current gives inductances. The inductance of the circuit depends on the current paths and the magnetic permeability of the nearer material.
The magnetic permeability shows the ability of the material to forms the magnetic field. Air Cored Inductor wound on non-ferrite material — The inductor in which either the core is completely absent or ceramic material is used for making the core such type of inductor is known as the air-cored inductor.
The ceramic material has the very low thermal coefficient of expansion. The low thermal coefficient of expansion means the shape of material remains same even with the rise of temperature. The ceramic material has no magnetic properties. The permeability of the inductor remains same due to the ceramic material.
In air core-inductor, the only work of the core is to give the coil a particular shape. The air cored structure has many advantages like they reduce the core losses and increases the quality factor.
The air cored inductor is used for high-frequency applications work where low inductance is required. Iron Core Inductor wound on ferrite core — It is a fixed value inductor in which the iron core is kept between the coil.
The iron-cored inductor is used in the filter circuit for smoothing out the ripple voltage, it is also used as a choke in fluorescent tube light, in industrial power supplies and inverter system etc. The inductor is an electrical device used for storing the electrical energy in the form of the magnetic field. It is constructed by wounding the wire on the core. The cores are made of ceramic material, iron or by the air. The core may be toroidal or E- shaped. The coil-carrying the electric current induces the magnetic field around the conductor.
The intensity of the magnetic field increases if the core is placed between the coil. The core provides the low reluctance path to the magnetic flux.Definition: Inductor is a device which stores energy in the form of magnetic field. When current flows through the inductor, it varies the flux linked with the component. Due to this magnetic field is induced around the inductor and thus the inductor stores energy in the form of magnetic field.
In a circuit, inductor opposes the sudden change of current in magnitude and direction. When current changes suddenly in magnitude or direction, then inductor induces a voltage. The inductor possesses the property to blocks AC and allows DC to pass through it. If in a circuit there is no sudden change in the current.
Basic Electronics - Types of Inductors
Then, it offers a high impedance to AC and low resistance to DC. The wire of any material possess the property of inductance, i.
If the wire is coiled in helix shape, the property of inductance will increase equivalent to the square of the number of turns. Inductance is represented by capital letter L, and its measuring unit is Henrys. The wire used in an inductor is made of copper, and it is coiled to achieve various turns to increase its inductance.
This copper wire is wounded on either on non-ferrite materials or ferrite materials depending upon the type of the inductor. If the copper wire is wounded on the non-ferrite material, it is called Air Core Inductor. The turns of the inductors will vary according to the particular application. A few turns Air Core Inductor possesses the inductance of 0.
It is suitable for the high-frequency application. If the wire is wounded on ferrite material, it is called Iron Core Inductor. The iron core inductors of inductance 50 H or more are suitable for low-frequency application. The inductors can also be classified based on the usage.
The various sub-types of inductors based upon the usage are filter chokes or inductor, radio — frequency inductor or choke and an audio-frequency inductor or choke. Filter choke is formed by wounding a wire around the iron core. The iron core is formed by combining laminated sheets in the shape of E and I.
Basic Electronics - Inductors
The filter choke is widely used in power supplies circuit for removing the AC ripples from pulsating current. The range of inductance of filter chokes is from 1 H to 50 H.
The current carrying capacity of filter chokes is mA. The audio-frequency chokes are smaller in size as compared to filter chokes. Thus they are suitable for operation at lower frequencies or audio-frequencies.
Due to small size, the inductance of audio-frequency chokes is lower than that of filter chokes. This is the reason they are suitable to provide an obstruction to audio-frequencies, i. The Radio-Frequency choke is formed by wounding wire on an air core. The number of turns in radio-frequency inductors is more than the audio frequency choke. The inductor thus formed is most suitable for a high-frequency application.
The range of radio-frequency inductor varies up to 2mH. In the above topic, we have discussed fixed inductors in which the value of inductance is fixed. In some application, we require variable inductors which possess values which change with the requirement. Such types of the inductors are known as variable inductors. In applications such as phase shifting or tuning circuits, we need to have variable inductors in the circuit.
The inductance of the inductor can be varied by changing the number of turns wounded on an iron core. And also by increasing the area of the core inside the turns of wire.
