Fixed inductors are electronic components that can store energy in the form of a magnetic field. The inductance of a fixed inductor is determined by its physical size and shape. The inductance of a fixed inductor is usually expressed in units of microhenries, or mH.

An inductor is nothing more than a coil of wire with several turns encircling a core or bobbin. The winding of an inductor forms an electromagnetic field around the core when a current is applied through it. This field is opposed to any changes in the applied current, thus, creating an inductance.

The RLB1314-472KL fixed inductor is an axial-leaded inductor with an inductance of 4700 microhenries (mH). It has a maximum AC current rating of 30 mA, a DC resistance of 0.266 ohms, and a maximum DC current rating of 5 amps. It has an approximately 22 kHz self-resonance frequency, which is quite typical for fixed inductors of this size.

The RLB1314-472KL provides high inductance with low DC resistance. When current flows through it, an inductive reactance is present, which increases with frequency. This property of inductors is exploited for a number of applications, such as filtering, signal conditioning, frequency selection, impedance matching, and even AC energy storage.

Applications of the RLB1314-472KL fixed inductor include voltage regulators, linear power supplies, power switching circuits, RFID readers, multiband antenna circuits, high frequency amplifiers, voltage controlled oscillators, etc. In each of these applications, the inductor helps to shape the waveforms of the output signal.

The working principle of the RLB1314-472KL fixed inductor is grounded in the principles of electromagnetic induction. When current passes through the inductor’s windings, it creates a magnetic field that opposes any change in the applied current, thus creating inductance. This opposing force is proportional to the rate of change of current in the inductor. The higher the frequency and/or current level of an applied signal, the greater the inductance.

Overall, the RLB1314-472KL fixed inductor is a versatile component that has a variety of applications. Its high inductance and low DC resistance makes it well suited for a range of applications, making it a great choice for designers of power and signal circuits.
