Fixed Inductors
IMS05ER221K
Fixed inductors, also known as fixed choke coils, are passive devices used in electronic circuits as inductors with inductance values that are not adjustable. They are usually made from ferrite rods, although other materials such as carbon, aluminium oxide, or magnetic steel can also be used. Fixed inductors are an essential component in many applications; they can be used for filtering, energy storage, voltage stabilizing, or other signal conditioning tasks.
The IMS05ER221K is a fixed inductor in the 0805 footprint, one of the most common sizes for surface mount inductors. It is rated for a maximum current rating of 3.8 A and inductance of 220 uH. It has a max DC resistance of 0.046 Ohm and a max self-resonant frequency of 1 MHz. It also features a ferrite core and is encapsulated in a UL approved flame-retardant 94V-0 case.
Application Field
The IMS05ER221K is ideal for a variety of applications, particularly those that require a low-profile inductor. It can be used for power-supply filtering, RF signal conditioning, inter-stage matching, EMI filtering, and other industrial and medical electronics applications. Due to its small size, it is also suitable for use in mobile devices and other space-constrained environments.
Working Principle
Fixed inductors use the basic principle of inductance — that a changing magnetic field will cause an electrical current to flow in a circuit. In the case of a fixed inductor, a current is passed through a coil of wire with a core material, usually ferrite. As current passes through the coil of wire, it creates a magnetic field which interacts with the core material, inducing an opposing magnetic field. This opposing magnetic field resists changes in current, creating a “back EMF” which acts as an inductor.
This back EMF also creates a voltage drop across the inductor as current passes through it, making the device useful for filtering and voltage stabilization. It also allows the inductor to work as an energy storage device capable of storing and releasing energy in the form of a magnetic field. This energy storage capability is useful in several types of applications, such as RF power amplifiers, filters, and oscillators.
Conclusion
The IMS05ER221K is an extremely useful fixed inductor with a broad range of application fields, from RF signal conditioning to inter-stage matching. Its versatile construction and low-profile size makes it a popular choice for use in many mobile electronic devices. It works on the same principle as most inductors, using a changing magnetic field to induce an opposing back EMF for energy storage and voltage stabilization.
