Fixed Inductors are commonly used components in electronic circuits. The application field and working principle of MLF2012DR39KT000 are largely based on electromagnetic field and electromagnetic induction. This series inductor primarily consists of a copper wire and an insulating material. When an electric current passes through the copper wire, a concentrating magnetic field is generated with the copper wire as core and the insulating material as insulation. Meanwhile, the rotating magnetic par along with the current will generate a counter electromotive force from the wire ends. The core component of MLF2012DR39KT000 is an intact encased iron or ferrite core, with multiple visible loops of insulated copper wires wound around it. The current conducted through the coil produces a concentrated magnetic field which passes through the core. The phenomenon of electromagnetic induction causes electric current to be induced in the coil. The electricity’s large electric resistance prevents much of the current from entering the core, thus producing inductance in the coil.

The core of MLF2012DR39KT000 inductor is made of some materials with high magnetic permeability and low coercivity, such as soft ferrite, iron powder, or Sendust. Such materials generate a minimal amount of eddy current on the surface of the core which, in turn, effectively reduces the magnetic loss. This ensures efficient operation and effective sensitivity when the current passes through the inductor. The structure also features a special method of winding the copper wire around the core, which compensates for the air gap of the concentrated magnetic field in the core. When the current flow is halted, the air gap dissipates the remaining magnetic field and prevents any of its interference on other components or circuits. In addition, due to the mutual inductance, the voltage developed across the winding of the coil will force other windings of the same induction coil to produce an opposite voltage.

The application fields of MLF2012DR39KT000 are wide-ranging, including all kinds of consumer electronics such as mobile phones, computers, automated devices, amplifiers, and motor controls. Moreover, these inductors can be labeled in applications including DC-DC converters, switching power supply, power supply regulators, over-current protection, energy storage, device protection, noise removal, electromagnetic interference limiting, audio frequency filtering, signal coupling/decoupling, SMPS circuits, radio frequency signal conditioning, and power line filtering. The working principle of the MLF2012DR39KT000 series can be explained by the following equation: V=L*dI/dT, where V is the voltage developed across the winding of the coil, L the inductance of the coil, and dI/dT is the rate of change of current flowing through it. The voltage output is critically dependent on the rate of change of the current. The more quickly the current changes, the larger will be the voltage.

The structure of an MLF2012DR39KT000 consists of an electrically conductive core wound with an insulated copper wire in a tight coil. The copper wire is usually made of copper or aluminum with a rated voltage range of 5V to 400V. The insulated core typically features insulation jacket type insulation around the core as well as a special winding technique which allows for an air gap in the core, thus facilitating efficient operation. The winding ensures uniform magnetic field over the entire inductor, eliminating any external disruption produced by the magnetic field.

All in all, the application field and working principle of MLF2012DR39KT000 are based on the electromagnetic field and electromagnetic induction, which provides a wide range of practical and reliable applications. This series inductor can be found in a range of consumer electronics and automations devices with its efficiency and effectiveness, and it is essential for many applications utilizing both DC and AC currents.
