Fixed inductors are electrical components that are essentially identical to those found within varying inductor applications and they are characterized by their ability to store energy in the form of a magnetic field. The 1220R-122F inductor is a popular product amongst a diverse range of electronics designs. It holds a unique place among the range of fixed inductors, mainly due to its various application fields and the wide variety of design features that it offers.

The 1220R-122F inductor is generally used in applications such as switching power converters, buck converters, boost converters, flyback converters, resonant converters and various other AC/DC and DC/DC power converters. It offers an efficient energy transfer due to its low AC resistance when compared to other inductors. It also features an excellent ESR over an extended frequency range, ensuring optimal performance when paired with power supplies and devices such as computers, LED’s, motor controllers, and various other electronic products.

In terms of design, the 1220R-122F inductor features a combination of a ferrite core and an air gap element, which is unusual for an inductor. This provides a higher than average inductance value per volume in comparison to other inductors from major brands. This makes it ideal for applications that require more efficient energy transfer in a lightweight package. The combination also provides greater stability when matching multiple inductors and a superior low frequency performance compared to traditional inductors.

In regards to the working principle of this inductor, it relies on the principle of induction. The electromagnetic field formed by an electric current induced in metal coil creates a toroidal field, which surrounds the component and stores energy in a series of magnetic flux lines. As current passes through the winding, the amount of lines increases and the field created by the induced electric current is concentrated in the core. The output current is directly proportional to the magnetic field strength and the number of field lines, which gives us the capability to predict the output current in relation to the input current.

The 1220R-122F is an 8x12mm compact inductor with a wide range of applications within the engineering and electronic industries. Its ferrite core and unique air gap element combination provides greater performance than traditional inductors, while also being more energy efficient. It works on the principle of induction and operates according to standard methods, making it an ideal choice for a range of energy conversion needs.
