Fixed inductors are devices that are designed to offer a constant inductance without any change over a wide range of frequencies and temperatures. They are the most common type of inductor and are usually found in electronic equipment, including power supplies, DC-DC converters, pulse shaping circuits, delay lines, analog filters, and low-noise oscillators. One of the common fixed inductors is the MPC1055L1R0C. This article will discuss the fields of application and the working principle of the MPC1055L1R0C.

MPC1055L1R0C Key Features

The MPC1055L1R0C is a 1055-series, fixed inductor with a 4.3mH inductance. It also has a 0.006 ohm resistance, a 0.83mm profile, and a DC current rating of 3.8A. The maximum DC surge current is 7.6A, and the temperature coefficient of inductance (TCL) is ?500ppm/?C. This fixed inductor comes in a EIA-4818 (1206) package with lead-free terminations.

MPC1055L1R0C Application Fields

The MPC1055L1R0C is a versatile fixed inductor with a wide range of applications. It is often used for DC-DC switching regulators, AC-DC adaptive and resonant converters, DC-AC inverters, antenna tuning, communication systems, and audio/video systems. It is also suitable for solar panel inverters, LED drivers, electric vehicle charging systems, and power line communication systems.

MPC1055L1R0C Working Principle

The working principle of a fixed inductor is fairly simple. Its core is made of a conductive material surrounded by a magnetic field. When an electric current runs through the inductor, it generates a magnetic field, and this magnetic field generates a back electromotive force (EMF). This back EMF then induces a voltage drop across the inductor. This is the same principle that applies to any inductor.

The magnetic field is generated by the coil of the inductor. It is the same as the magnetic field generated by an electromagnet - the more turns the coil, the stronger the magnetic field. The core of the inductor also acts like an electromagnet. It will amplify the magnetic field and allow for higher inductance values.

The inductance value for any inductor is determined by its core material, number of turns on the coil, and physical size of the core. The MPC1055L1R0C uses a ferrite core material, which allows it to achieve the 4.3mH inductance value without having a high number of turns. This makes it ideal for power regulation applications where high inductance values are required without sacrificing space.

Conclusion

The MPC1055L1R0C is a versatile fixed inductor that is suitable for a wide range of applications including power supplies, DC-DC converters, and other power regulation applications. Its key features include a 4.3mH inductance, 0.006 ohm resistance, a 0.83mm profile, and a DC current rating of 3.8A. The working principle of a fixed inductor is based on the generation of a back EMF, which induces a voltage drop across the inductor. The inductance value is determined by the core material, number of turns on the coil, and physical size of the core.
