Fixed inductors are essential components of electronic circuits. MPLCH0740L4R7, as one of the common fixed inductors, features high reliability in high frequency converter circuits and high current applications. This paper will introduce the application and working principle of MPLCH0740L4R7.

Application of MPLCH0740L4R7

MPLCH0740L4R7 is a miniature rectangular multi-layer chip inductor. It is particularly suitable for high frequency converter circuits and high current applications. Thanks to its low profile design, it can be easily installed onto the PC board. Moreover, the coil overlapping technique can further reduce the size and make this package a space-saving option.

It is mainly used for decoupling, modeling, shielding, EMI/RFI filtering, and inductive current or voltage sensing. It can also be used for measuring DC voltages, impedance or phase measuring, antenna tuning, and blocking or bypassing signals. In power supplies, this inductor is used in the development of the DC-DC converter filter, rectifier, battery charge and discharge circuit, etc. In addition, in automotive applications, this inductor is often used in power steering controllers, Anti-lock Braking System (ABS) modules, and air conditioners, etc.

Working Principle of MPLCH0740L4R7

The working principle of MPLCH0740L4R7 is based on the generation of a magnetic field by applying a current to the coil of wire wound around an iron core. When a current passes through a coil of wire, it generates an electromagnetic field in the vicinity of the core. This field interacts with the core and generates an induced voltage. The induced voltage is perpendicular to the flow of current in the coil. The magnitude of this voltage depends on the rate of change of the current in the coil.

Furthermore, an inductor can also be used in a circuit to oppose changes in the current. This property is known as inductance. The inductance of an inductor is directly proportional to the number of turns in the coil and inversely proportional to the cross-sectional area of the coil. Hence, the number of turns and the diameter of the coil in an inductor will determine its inductance.

These features make MPLCH0740L4R7 particularly suitable for high frequency applications, which require quick response time and high voltage ratings. In addition, it can also offer EMI/RFI noise reduction in order to make the signal transmission more efficient. With its high power efficiency, it is capable of supporting complex circuit configurations.

Conclusion

MPLCH0740L4R7 is a miniature rectangular multi-layer chip inductor with excellent features for high frequency converter circuits and high current applications. It is extremely power efficient and can support complex circuit configurations. It is particularly suitable for decoupling, modeling, shielding, EMI/RFI filtering, and other applications in the automotive, power supply, and high frequency fields. In summary, MPLCH0740L4R7 is a great choice of inductor for many electronic applications.
