Fixed inductors, also known as chokes, are passive two-terminal electrical components used to store energy in the form of a magnetic field. They also provide an inductive impedance to an electrical current, and can be used to filter out certain frequency ranges from a signal. The MHQ0402P4N6HT000 is a chip-type inductor part made by Murata Electronics, and it has a wide range of applications for various sectors, including aerospace, automotive, and consumer electronics.

MHQ0402P4N6HT000 is an inductor designed specifically for DC-DC converters. It has a wide operating temperature range of -40~+125°C and a high maximum DC current of 3.5A. This makes it suitable for use with higher power signals. It also has a high rated inductance of 4.7uH and a low ESR resistance of 0.027 Ohm, which gives it a larger than nominal inductance when used at higher frequencies. This makes it suitable for use in high-frequency applications such as switching power supplies and DC-DC converters.

The working principle of the MHQ0402P4N6HT000 is based on the theory of electromagnetic induction. When current passes through the inductor’s windings, it creates an electromagnetic field that causes an opposing voltage, known as its back EMF. This opposes the current’s flow, creating aresistive force that reduces the power, or voltage, of the current. This reduces the current’s energy, which in turn, creates a decrease in power or frequency.

The MHQ0402P4N6HT000 is used for many different applications, but the most common use is as an output filter for DC-DC converters. It reduces the noise on the output without significantly affecting the output voltage, making it a useful component for applications that require a clean output voltage. It can also be used to suppress EM interference, providing an effective solution for protecting other components in the system.

The MHQ0402P4N6HT000 can also be used in AC applications, including high-frequency switching circuits and signal processing networks, as well as ripple reduction applications. It is also used in flyback power supplies and motor control circuits, where it can reduce the noise and increase the efficiency of the circuit.

Overall, the MHQ0402P4N6HT000 is a versatile inductor component that can be used in a wide range of applications. Its high current and wide operating temperature range make it suitable for high power and high frequency circuits, while its low ESR resistance provides a larger than nominal inductance. This makes it a great choice for noise and frequency suppression, ripple reduction, and other critical applications.
