Proprietary 5H and 10H ferrite materials and equivalent.It can be used at high and medium frequencies.Mixing Iron oxide (Fe2O3) in combination with other metal oxides like (Mn), zinc(Zn) or magnesium(Mg) at a temperature of 1000° C - 1300° C will result in a material with very interesting magnetic properties called ferrite.įerrite core inductors have high permeability, high electrical resistivity and low eddy current losses these characteristics make them suitable for many high-frequency applications. So, what is a Ferrite core and when should we use it? It is used in high-frequency applications including TV and radio receiversīy winding a length of wire around a ferrite core will result in a ferrite core inductor.It is used to ensure a lower peak inductance,.The air core inductor is used in filter circuits.It is used for constructing RF tuning coils.The core material is air, so it has low permeability hence lower inductance so, it can be used for high-frequency applications.
Insulation System - Class B insulation, 130° Cīy taking a cylindrical material of specific diameter (like a drill bit) as a template, we can wrap around a length of wire to make an air-core inductor, further the inductance can be stabilized by dipping the inductor in varnish or securing it by wax. To make a laminated core inductor, a wire is wrapped around the bobbin of the inductor, then the E and I plates are placed inside the bobbin one by one to form the core, this E and I sheets are made out of steel with high silicon content and its heat-treated to produce high permeability and to lower the hysteresis and eddy current losses. The elements of a laminated core inductor consist of a bobbin, a laminated core, and a coil which is wrapped around the bobbin. The standard unit of inductance is the henry.ĭepending on the application there are many types of inductors, they come in various form factors, there are high-frequency inductors, low-frequency power line inductors, and some specially designed inductors for decoupling and filter applications, below we will discuss different types of inductors in details. The main characteristic of an inductor is its ability to resist changes in current and store energy in the form of a magnetic field. Inductors are often referred to as "AC resistance". In this tutorial, we are going to know about different types of inductors and how to choose an inductor for different applications. We have already covered the introduction to a resistor and its different types, and also covered capacitors and its different configurations. There are only three basic components in any electronic circuit design- resistor, capacitor, and inductor.
