Fixed inductors are a type of inductor designed to produce a stable, predetermined amount of inductance, regardless of variations in the electrical environment or temperature. The MLG0402P0N6CT000, a miniature low-profile surface-mount magnetically-shielded multilayer chip inductor made up of molded resin coils, is one of the most commonly used fixed inductors. This article will discuss the application field and working principles of this specific inductor.

1. Application Field

The MLG0402P0N6CT000 is most often used for DC/DC converters, clock circuits, and power supply circuits. It is also commonly used in RF and high-frequency circuits, current and impedance matching circuits, filter circuits for noise suppression and circuit isolation, memory modules, transceivers, and many other applications. Its dimensions of 4.0mm x 2.0mm allow it to fit into highly space-limited applications.

The MLG0402P0N6CT000 is frequently used in applications in which stable, low-noise performance is paramount. Wideband operation is possible due to its low DC resistance feature. The MLG0402P0N6CT000 also has good Q characteristics and excellent temperature stability. Due to its robustness and stability, it is well-suited for applications that require sustained, consistent operation.

2. Working Principle

The circuit of the MLG0402P0N6CT000 consists of a series of layers of molded resin coils, which is referred to as a photolithographic process. This process consists of a combination of mechanical and chemical steps. An air-gap is provided between the layers of coils to reduce eddy current losses. The overall meandered pattern of the coils is based in a single plane, with the cores of the coils being placed in the center and the ends of the inductors placed towards the external walls of the device.

As the current flows through the inductor, the field produced is responsible for the inductance. The inductance of the device is determined by the number of turns in the coil, the number of layers, and the physical properties of the material used. The MLG0402P0N6CT000 has a maximum inductance of 6nH. This inductance remains more or less constant over a wide range of frequencies, temperatures, and currents.

The MLG0402P0N6CT000 is encapsulated in an epoxy resin material to ensure stability and resist environmental changes. The epoxy casing also ensures that the magnetic shielding performance is not adversely affected. The device is rated for operation from -55 to 125 °C.

Conclusion

The MLG0402P0N6CT000 is one of the most popular fixed inductors available on the market. It is most often used in DC/DC converters, clock circuits, and power supply circuits, but it can also be used in many other applications. Its low DC resistance and wideband operation allow it to perform reliably in different electrical conditions. Its stable inductance over a wide range of frequencies, temperatures, and currents make it an ideal choice for applications where consistent performance is a must. Overall, the MLG0402P0N6CT000 is a highly reliable and robust fixed inductor that is well-suited for a variety of applications.
