The 47uH (470 nH) SMD 12mm inductor is a fundamental component in electronic circuits, designed to store energy in a magnetic field. The inductance value of 47 microhenries (uH) or 470 nanohenries (nH) signifies its ability to oppose changes in current. This property is crucial in regulating current flow within circuits, ensuring stability and efficiency. This inductor is specifically crafted for soldering onto the surface of a printed circuit board (PCB), rather than through holes.

SMD inductors like this one find extensive use across numerous electronic applications, including power and signal filtering, impedance matching, and DC-to-DC conversion. They are instrumental in enhancing circuit performance, minimizing noise, and ensuring efficient power transmission.

In conclusion, the 47uH (470 nH) SMD 12mm inductor represents a versatile and indispensable component in electronic circuitry, enabling efficient energy management and signal processing in various applications.
