Fixed Inductors

A Fixed Inductor, sometimes referred to as a coil, is a passive electrical component consisting of a length of wire or ferrite rod, wound in a coil, which is designed to create a magnetic field when energized with an electric current. Fixed Inductors are used in myriad applications from high-frequency radio antennae to electronic power supplies, amplifier circuits, and even local area networks (LANs).

4470R-30F Application Field and Working Principle

The 4470R-30F Fixed Inductor is employed in networking, telecommunications, and other RF applications. Operating at an inductance value of 30 uH (microhenrys, also referred to as millihenrys), it has a maximum operating frequency of 4 GHz. This component features an insulation rating of 308 Vrms (volts root mean square), and low DCRS of 0.35 OHMS (ohms) for great signal integrity.

The 4470R-30F Fixed Inductor uses an air-core construction, which is often used in radio frequency, or RF, circuitry, as wetted cores are too lossy. Air-core inductors are wound from enameled wire, and insulation is typically applied with a lacquer or wax-like substance. Although air-core inductors act as effective frequency-dependent elements, they offer poorer properties than ferrite core inductors at higher frequencies, as they suffer from eddy current losses which can not be avoided.

4470R-30F operates as a passive component in many wireless networks, receiving and transmitting data through the air. This component works by generating a magnetic field when energized with an electric current, thus converting electric energy into magnetic energy. The inductor stores this magnetic energy, which is created due to the change of current. When the current is shut off, the magnetic energy is released and converted back to electrical energy. This process continues back and forth, ensuring the efficient transfer of data from one point to another.

In summary, the 4470R-30F Fixed Inductor component is an air-core device which operates at an inductance value of 30 uH and a maximum frequency of 4 GHz. It is widely used in RF applications to capture and transmit data from one point to another. This coil generates a magnetic field when energized with an electric current, thus converting electrical energy into magnetic energy, and vice versa.
