Inductors are used across various industries and applications to create impedance, store energy, and modulate the flow of current. An inductor is a two-terminal electrical component that stores electrical energy in a magnetic field when electric current flows through it. When current passes through its windings, it resists the changes in current and alters it accordingly. This means that when the current increases, the inductor will stabilize it by turning the excess current into magnetic field. And, when the current decreases, the energy stored in the magnetic field is converted into current and added to the decreased current to boost it up. This quality of inductors has helped them gain a position in applications like analog circuits, signal processing, switched mode power supplies, radio frequency equipment, transformers, electrical transmission systems, etc. For any such applications, if you are looking to purchase high quality inductors, get in touch with Miracle Electronics, the renowned inductor coil manufacturer in India, who has been successfully providing a variety of UU, EE, EI, and many other inductors to clients across the globe for more than the past two decades. However, before purchasing your inductors, there are some basics you need to know about these tiny yet important components.
Inductor core
The most important part of an inductor – the core – is available in a variety of shapes and materials to suit the specific circuit type and power requirements. The shape and material of an inductor’s core highly impact the properties and applications of the inductor. The most common materials used to construct the core include silicon steel, iron, ferrite, and nickel. Also, air core or no core inductors are available, depending upon the customer requirement.
Inductor wires and winding
Inductors have wires wound around the core in the form of a coil to increase the number of times the magnetic flux lines link the circuit, increasing the field and thus the inductance. Therefore, more turns mean higher inductance. How the wire is wound around the core is one of the main considerations while designing an inductor, as this is what affects every measurable inductor property. Everything from the wire material to size to shape to winding to frequency and pattern must be carefully chosen, as all of this determines the coil losses.
Inductor applications
As mentioned above, inductors can be used in a wide range of applications. Different inductors are used in different kinds of applications for serving different purposes, as listed below.
Common mode inductors are used to obstruct noise in high-frequency applications.
Differential mode inductors are used in applications wherein current cannot be obstructed by an opposing current.
Toroidal common mode inductors are used in switched-mode circuit noise or EMI reduction applications.
To ensure optimal performance and durability of your inductors, you should consider the above mentioned three factors while making a purchase. You should have your inductors meet your particular applications’ unique circuit requirements so that they can perform to their potential. No matter how restricted your application, you can have your inductors designed and customized to meet your specific needs if you approach Miracle Electronics, the leading inductor coil manufacturer in India.
