Fixed inductors refer to electronic components composed of an insulating core, a coil composed of a conductor, and external connecting wires. They play a role in filtering and coupling circuit. Fixed inductors, also known as choke coils, are composed of magnetic core, and its structure is divided into air core coil and magnetic core coil. M1331-472K belongs to magnetic core coil, which refers to the inductor formed by winding resistance wire on a ferrite core.

The M1331-472K is an integrated magnetic core coil developed by the electronics producing company Taiyo Yuden. The wire is of 1.6~0.4mmAWG30~AWG28 in size and has an inductance of 470uH±20%. The direct current resistance (DCR) of this product is 100mΩ max and its rated current is 600mA. This product meets the requirements of UL 94V-0 flame retardant grade 1 and is certified by RoHS and REACH. For ambient temperature below 70℃, the temperature rise is 30K. The terminal has a soldering area below 3.3mm for the user to make the welding part more secure. The product is suitable for switching power supply, electrical appliances, audio, communication devices, car equipment, home electronics, etc.

The working principle of the M1331-472K is as follows: when an alternating current flows through the inductor, the passing current flows through the coil and generates a relatively static magnetic field. During the process of alternating current, the lines of force in the magnetic field are subject to directional changes. According to Faraday\'s law of electromagnetic induction, eddy current is generated in the coil. As the eddy current flows to the ground, the field of the coil weakens. The weakened field strength tries to maintain the current initially added to the coil, until it is finally zero. As the alternating current frequency increases, the terminal voltage of the inductor also increases.

In summary, the M1331-472K is a 470uH inductor developed by Taiyo Yuden and belongs to the fixed inductor category. The origin size is 1.6~0.4mmAWG30~AWG28 and has a maximum direct current resistance of 100mΩ. This product has a remarkable temperature rise of 30K and passes the RoHS and REACH certifications. The working principle of this product is based on the Faraday\'s law of electromagnetic induction. The application field of the M1331-472K includes switching power supply, electrical appliances, audio, communication devices, car equipment, home electronics, and more.
