Fixed inductors are electrical components that are used to induce voltages and in particular, they help curb and stabilize the flow of current at a certain level. The SPM3015T-R47M-LR, a specific type of fixed inductor, is particularly well-suited in applications looking for a low impedance, high-current, and low-profile inductor.

The SPM3015T-R47M-LR’s main materials used in its construction are ferrite cores, with tinned copper wires wrapped around the outside of the core. The terminals are made out of nickel-plated steel. The inductor is designed to shield its core against temperatures of up to 130℃, withstanding both low and high heat in extreme environments.

The SPM3015T-R47M-LR is most commonly used in high-frequency power conversion circuits, like power supplies, displays, and 4G application modules. Its features of low profile, low DC resistance, and high current-handling capabilities fit perfectly for powe-consuming applications such as power converters for charging laptops and other portable electronics, developing digital TV receiver cards, and more.

The working principles of the SPM3015T-R47M-LR can be divided into two parts: magnetic laws of induction and some resistance produced by winding copper wires. The inductor works by making a magnetic field using current from an alternating current(AC) source.When the AC source creates an ever-changing field-causing electrons to vibrate—the inductor will also experience a change in current. This current serves as the inductor’s output voltage.

The copper wires along the inductor core act as a variable resistor, offering some resistance to the flow of electrons. This resistance from the wire helps to stabilize the current, until the electrons reach a certain level. As the electrons hit this pre-determined level, the current begins to dip back down. This continuous movement of current results in an output voltage that remains relatively stable.

The SPM3015T-R47M-LR\'s unique design allows it to act as both an inductor and a resistor in one component. Its combination of low impedance and high current-handling capabilities make it an ideal option for both power-hungry applications and circuits that require stable voltage levels. This fixed inductor is specifically designed for the purpose of inductance, offering reliable performance even in extreme environmental conditions.
