Introduction to Fixed Inductors
Fixed inductors are passive components, consisting of a thin wire wound into a coil. Inductors are used in electronic circuits to store energy in the form of a magnetic field. The inductance of a fixed inductor is determined by the number of turns in the coil, its shape, and the material it is made out of. They can be used in a variety of applications, such as filters, oscillators and pulse generation, energy storage, and impedance matching.
ATCA-04-221M-V Application Field
The ATCA-04-221M-V is a fixed inductor manufactured by ATCA. It has an inductance of 0.47mH, a current rating of 1.2A, and a saturation current of 2.5A. Additionally, it has a self-resonant frequency of 125MHz and an operating temperature range of -40°C to +85°C. The ATCA-04-221M-V is mainly used for signal conditioning, filtering, and impedance matching. Its low profile design makes it ideal for use in high-density circuit boards.
ATCA-04-221M-V Working Principle
The ATCA-04-221M-V works on the principle of Faraday’s Law of Induction. When an electrical current is passed through a coil, it induces a magnetic field. This magnetic field then induces a voltage or current in an adjacent conductor due to electromagnetic induction. The magnitude of the induced current or voltage is proportional to the rate of change of the magnetic field. This relationship forms the basis of how inductors work.
Conclusion
The ATCA-04-221M-V is a fixed inductor commonly used in signal conditioning, filtering, and impedance matching. It has a low profile design, high current rating, and a wide operating temperature range. The inductor works on the principle of Faraday’s Law of Induction, which states that a changing magnetic field will induce an electric current or voltage in an adjacent conductor. This article has discussed the application field and working principle of the ATCA-04-221M-V fixed inductor.
