Introduction

Fixed inductors are basic components of electrical and electronic circuits, and serve as an important link between the energy storage and conversion elements of a circuit. They store energy in two forms: electrostatic energy in the form of electric fields and electromagnetic energy in the form of magnetic fields. Among the various types of fixed inductors available, one of the most popular is the MGV12074R7M-10.

Application field of the MGV12074R7M-10

The MGV12074R7M-10 is a fixed film inductor used primarily in DC/DC converters. It is designed for power applications in applications such as synchronous rectification DC/DC converters, synchronous-buck DC/DC converters, high efficiency DC/DC converters, and battery-fed converters. It is well suited for use in audio applications due to its low distortion. In addition, because the inductance is well insulated, it does not interfere with other circuits or components.

Working principle of the MGV12074R7M-10

The MGV12074R7M-10 is based on a two-layer film design. It consists of a capacitor layer sandwiched between two ferrite/magnetic core layers. The capacitor layer acts as an impedance matching network, while the ferrite/magnetic core layer helps generate an inductive field in the winding gaps.When an alternating current is passed through the inductor, the ferrite/magnetic core layers help to create a magnetic field around the winding, causing the inductance to increase or decrease depending on the orientation of the alternating current. The capacitor layer also plays a role in controlling the inductance, as it acts as an impedance matching network between the components in the inductor.

Conclusion

The MGV12074R7M-10 is a fixed inductor ideal for use in DC/DC converters. Its two-layer design consists of a capacitor layer and a ferrite/magnetic core layer, which helps to create a magnetic field around the winding, increasing or decreasing the inductance depending on the current direction. In addition, the capacitor layer helps to control the inductor’s impedance, allowing for precise tuning and matching of components in the circuit.
