Fixed inductors are devices that are made with a coil of metal wire, either wound or etched on a substrate, that have no external input connections. The wire coil is wound or etched onto a substrate dielectric or ferromagnetic material. This coil is connected to a capacitor or another type of inductor to form a resonant circuit that maintains a constant frequency.

The RCR875DNP-220L is a type of one kind of total fixed inductors. It offers a cost effective solution for DC-DC converters, battery charging and LED lighting applications. The RCR-875DNP-220L is a general purpose fixed inductor. It has an inductance range of 0.22μH to 4.7μH, which is ideal for the low frequency applications.

The working principle of the RCR875DNP-220L is based on Lenz\'s Law. According to Lenz\'s Law, an electric current produces a magnetic field, and when this magnetic field interacts with an external magnetic field, an electrical current is induced. This current opposes the external field. The electrical energy in the magnetic field travels in circles and forms a loop. When the loop is closed, an electric current will flow.

The core material for the RCR875DNP-220L is Powder Iron core, and the core Style is SEP Core. This fixed inductor can operate in temperatures ranging from -25℃~125℃. It has a maximum voltage of 60V and a rated current of 1.2A. The device is composed of a non-inductive coil of Mylar film wound with copper and iron wire. The wires are wound around the powder iron core in a specific pattern to maximize inductance while minimizing impedances.

The RCR875DNP-220L is employed in the field of DC-DC converters, such as DC-DC converters for laptop computers. It is also used in battery charging applications, as well as LED lightning and mobile phone applications. The RCR875DNP-220L features low profile, low temperature coefficient, high power density, high current capability, and high reliability. It produces a magnetic field to transfer energy from one coil to another. The magnetic fields produced by the current through the inductor coil allow the RCR875DNP-220L to store energy and easily transfer it to other parts of the circuit.

In conclusion, the RCR875DNP-220L is an ideal fixed inductor for low frequency applications. It is employed in DC-DC converters, battery charging, LED lighting and mobile phone applications. It uses a Powder Iron core and a non-inductive coil of Mylar film. It is constructed with a specific winding pattern to maximize inductance and minimize impedances, while providing a low profile, low temperature coefficient, and high power density. The current flowing through the coil produces a magnetic field which allows this inductor to store and transfer energy.
