Fixed inductors—also known as chokes, coils, or reactors—are components used to store energy within a magnetic field and resist changes in current. The MLG0402Q8N2HT000 is a miniature, low-profile, wirewound inductor created by Murata Manufacturing Co., Ltd. for circuit boards and other electronic applications. This article will describe the application field and working principle of the MLG0402Q8N2HT000.

Application Field

The MLG0402Q8N2HT000 is a miniature, low-profile inductor with a unique construction and design that makes it ideal for a variety of applications, including:

• Power supplies
• DC/DC converters
• Pulse-width modulation (PWM) control systems
• DC motors
• Automotive audio systems
• Noise suppression

The MLG0402Q8N2HT000 can also be used in scientific instruments, medical devices, consumer electronics, and computers.

Working Principle

A fixed inductor works by storing energy within a magnetic field generated by the current passing through a coil of wire. This magnetic field resists changes in current, leading to a phenomenon called inductance. The inductance increases when more wire is used to construct the coil, while decreasing the number of turns will reduce the inductance. The MLG0402Q8N2HT000 is constructed with small wires and an optimized winding pattern in order to achieve the highest inductance possible in a low-profile package.

When an alternating current (AC) is applied to a fixed inductor, the rate of change in current determines the amount of energy that is stored in the magnetic field and the amount of magnetic flux that is generated. The inductance of an inductor will decrease as the frequency of the AC input increases, while its capacitance increases as the frequency decreases. The MLG0402Q8N2HT000 is designed to work optimally with frequencies up to 100MHz.

The MLG0402Q8N2HT000 is a key component in many electronic circuits and power supplies, helping to protect against voltage spikes, regulate the flow of current, and suppress noise. Its low profile design makes it ideal for use in compact electronic and automotive applications.

Conclusion

The Murata MLG0402Q8N2HT000 is an ideal choice for a variety of electronic and automotive applications where a low-profile, high-inductance inductor is required. Its optimized winding pattern, low profile design, and high frequency capabilities make it especially well-suited for power supplies, DC/DC converters, PWM control systems, and noise suppression circuits.
