Fixed Inductors

Inductors, also known as coils or chokes, are passive electrical components that are used to store energy in the form of a magnetic field. Fixed inductors, in particular, refer to inductors with a determined inductance value and relatively low current rating. An example of a fixed inductor is the MLG0402Q3N9BT000, which is designed for a wide range of consumer applications.

Applications

The MLG0402Q3N9BT000 inductor is primarily used in low-power consumer electronics, such as mobile phones, personal computers, and home entertainment systems. Due to its small size, the MLG0402Q3N9BT000 is suitable for use in portable devices such as portable DVD players and netbooks. Further, its small physical size allows for improved aesthetics and improved circuit board utilization.

The MLG0402Q3N9BT000 inductor is also used in other consumer electronics applications, such as AC/DC adapters, LCD display power supplies, and charger circuits. Additionally, since it is capable of withstanding high surge currents, the part is suitable for use in applications where there is a high possibility of frequent inrush and over-current events, such as automotive systems.

Working Principle

The MLG0402Q3N9BT000 consists of a core that is typically made of ferrite, a ferromagnetic material. It is wrapped in copper wire. When the current flowing through the coil increases, a magnetic field is created in the core that resists the flow of current, which is known as inductance. This causes the current to lag behind the voltage, which results in the inductor introducing a phase shift in an alternating current.

In addition, fixed inductors also serve as a type of filter to block out certain frequencies. This can be useful for applications where a certain frequency needs to be filtered out or a voltage needs to be stabilized. For example, an inductor can be used in a power supply to filter out noise and filtering of RF signals.

Conclusion

The MLG0402Q3N9BT000 is a small and robust fixed inductor that is suitable for use in low-power consumer electronics, such as mobile phones, personal computers, and home entertainment systems. It is capable of withstanding high surge currents and providing efficient inductance in a small form factor. Furthermore, it can also be used as an effective filter, allowing for the filtering of noise and RF signals.
