Inductors, also called coils, chokes, or reactors, are passive electrical components used for energy storage or coupling of signals. An inductor resists changes in current flow and, consequently, stores energy in a magnetic field. The 78F1R5K-RC application field and working principle applies to fixed inductors specifically.

Fixed Inductors

Fixed inductors are components that are used to store energy in a magnetic field. They carry a rating marked on the body of the component and represent their limit of current carrying capacity. It is important to keep in mind that these limits are usually measured under ideal operating conditions. Factors such as temperature, high amounts of energy, inrush, etc. can reduce these ratings significantly. Inductors usually consist of a coil of copper, enameled or bare wire, wrapped around a ferrite core, with terminal leads.

78F1R5K-RC Application Field and Working Principle

The 78F1R5K-RC fixed inductor is characterized by an inductance value of 1.5uH, a DC resistance (DCR) of 0.079 ohms, a rated current of 2.2A, and a rated surge current of 8.8A. Additionally, the inductor is designed to be RoHS compliant and AEC-Q200 qualified.

The current through the inductor creates an opposing magnetic field in the core. The magnetic field increases as the current increases, and the magnetic field collapses when the current stops. During this process, the magnetic field energizes the core and stores energy. The opposite happens when the current decelerates. This energy stored in the core is released back into the circuit, creating a back emf or voltage displacement. These voltage displacements help determine the paired reactance of the inductor to the impedance of the parallel circuit.

78F1R5K-RC fixed inductors are widely popular in a host of power applications such as switch mode power supplies, DC-DC converters, charging circuit protection and other power conversions. Their low DCR values are ideal for current carrying and power conservation requirements.

Conclusion

The 78F1R5K-RC fixed inductor is an excellent choice for a wide range of power applications and operations. Its low DCR values enable it to ideal for current carrying and power conservation requirements. With its rated current of 2.2A and surge current of 8.8A, it is a perfect fit for a number of power applications.
