Fixed inductors are usually used to store energy, filter frequencies, induce, and provide isolation between circuits. The DC1390R-125K is one particular type of fixed inductor that is used in a variety of applications. Here, we will discuss its application field and working principle.

DC1390R-125K Application Field

The DC1390R-125K is a small, cylindrical device that is generally used to construct high-frequency circuits. It can be applied in circuits for telecommunication, digital and analog buses, audio filters, and EMC-sensitive applications. These inductors are also frequently used in the automotive industry, where they can contribute to an increase in the efficiency of radio-frequency applications. The DC1390R-125K also features high power saturation and low leakage current. Moreover, due to their high self-resonance frequency and high ESR levels, these inductors work with excellent levels of attenuation.

DC1390R-125K Working Principle

The DC1390R-125K’s working principle is fairly straightforward. It involves a cylindrical core that is wrapped in multiple layers of copper wire. The copper wire directly influences the inductor’s frequency range, current level, and inductance value. An alternating current passing through this wire induces an electro-magnetic element referred to as inductance. The resulting electro-magnetism prevents AC current from passing through the wire. This is because the stored and induced energy in the form of heat prevents any electrons from passing through. This stored energy is then used to discharge the energy when required, in order to reduce the frequency or current of the system.

Conclusion

The DC1390R-125K is a fixed inductor that can be used for many applications, especially telecommunication, audio filtering and EMC-sensitive applications. Its working principle is based on the presence of a coil of copper wire wound into a core, which induces inductance in the form of electro-magnetic energy. The stored energy is then used to reduce the frequency or current of the system, whenever needed.
