Fixed inductors, also known as chokes, are well-known components of electronic circuits. Their primary function is to impede or "choke" alternating current flowing through the circuit by providing an inductance, that is, the ability to store energy in a magnetic field. The MHQ0402P3N9CT000 is a product of the Murata Corporation, and is an example of a fixed, non-polarized, radial leaded inductor.

This component features a diameter of 0.040” and a length of 0.086”. The ratings for the inductor are a maximum DC resistance (DCR) of 3.09 Ω, an inductance of 3.3 nH, an operating temperature of -25°C to 85°C, and a current rating of 1.0A. The SRF (self-resonant frequency) is also rated at 2.1 GHz. The MHQ0402P3N9CT000 is composed of a ferrite core, with the coil wrapped around the core, and a ceramic substrate covered in metal.

The primary application of the MHQ0402P3N9CT000 is power line filter inductor. It is used to reduce high frequency noise from power lines, ensuring that other components of the circuit do not become affected. The MHQ0402P3N9CT000 is also used in other applications, such as high frequency switchmode power supply circuits, RF or clock signal filters, or for any application that requires stable, reliable inductance.

The primary principle of operation of the MHQ0402P3N9CT000 is very simple. When current flows through the coil, a magnetic field is generated. This magnetic field will oppose further current flow, thus providing inductance. As current fluctuates, the magnetic field will also vary, thus providing the stability and reliability that is sought after in such applications.

The MHQ0402P3N9CT000 fixed inductor is a relatively small, but essential component, in many circuits. Its primary role is to provide added stability and filtering, for applications such as power line filtering, and high frequency switchmode power supplies. It operates on the very basic principle of magnetic induction, where a varying current flow will generate a magnetic field, and this field will oppose further current flow.
