Fixed inductors, also known as chokes, are passive two-terminal electrical components that store energy in the form of magnetically induced electric charge. The 12LRS475C is a fixed inductor manufactured by Murata, specifically designed for use in computer motherboards and telecommunications equipment. The 12LRS475C is popular among engineers for providing improved noise suppression and filtering capabilities at a low resonant frequency.

Applications of the 12LRS475C include cell phone receiver circuits, soundcards, communications systems, and motherboards. The device is composed of a ferrite core, which is wrapped by a copper coil to form an inductor. It can be used to reduce electromagnetic interference and radio frequency interference, and help regulate the voltage of a circuit. The inductor also functions as a filter to reduce unwanted frequencies while allowing the desired frequency to pass.

The 12LRS475C has a rated inductance of 470 nH, a rated DC resistance of 0.128 Ω, and a rated current of 1.5A and an operating temperature range from -25°C to +85°C. It is housed in a 0603-sized package, and has a cross section of 0.1 x 0.6mm.

The working principle of the 12LRS475C is based on Faraday\'s Law of Induction. Faraday\'s Law states that when a current is flowing through a coil of wire, a magnetic field is generated perpendicular to the coil. This in turn induces an electromotive force (EMF) in the coil. The 12LRS475C works similarly: when an alternating current (AC) flows through the coil, the associated magnetic flux induces an EMF in the coil. This EMF is capable of acting as a voltage source, and can be used to increase or decrease the voltage of the circuit.

In addition, the 12LRS475C possesses the ability to filter and reduce unwanted frequencies. This is achieved through the electromagnetic fields generated by the coil, which can block the flow of current at certain frequencies. This allows the component to filter out unwanted frequencies and only allow the desired frequencies through.

The 12LRS475C is a highly sought after component in the electronics industry, due to its ability to provide improved noise suppression and filtering capabilities, while still maintaining a low resonant frequency. It is ideal for applications such as computer motherboards and telecommunications equipment, where its ability to reduce electromagnetic interference and radio frequency interference is paramount.
