MLF2012K470M

Fixed Inductors

The MLF2012K470M is a type of fixed inductor. It is a very common inductor, much used in electrical and electronic engineering because of its various beneficial features.

Application Field

The MLF2012K470M is often used for power supply filtering applications. Its ability to store energy is useful for supplying a continuous output of power to circuits that use pulsed current. Another application of this type of inductor is EMI/RFI suppression, where the inductor can exhibit low impedance at high frequencies.This inductor can also be used in radio-frequency (RF) applications such as telecommunications towers, satellite dishes and WiFi routers. It is also used as a variable inductor for tuning, due to its relatively low inductance drift and high inductance range.

Working Principle

When the MLF2012K470M is connected to a direct current (DC) power source, it creates a magnetic field around the inductor. This magnetic field then induces a voltage in the inductor that is proportional to the rate of change of the current flowing through it. This process is known as self-induction, one of the most fundamental principles of electricity.The self-induced voltage opposes the current that created it, and is the basis for the so-called "back EMF” effect, which is the basis for the operation of generators, transformers and other electrical components.As the current through the inductor increases, the size of the induced voltage also increases, until it reaches a point where it is equal in magnitude and opposite in direction to the applied voltage. At this point, the current flowing through the inductor reaches its limiting value, and the inductor resists any further increase in current.

Conclusion

The MLF2012K470M fixed inductor is a very common type of inductor that is often used for power supply filtering and EMI/RFI suppression applications. It is also used in RF applications such as telecommunications towers and WiFi routers, as well as for tuning, due to its low inductance drift and high inductance range.The working principle of the MLF2012K470M is based on the principle of self-induction, and its induced voltage counteracts the current running through it. As the current increases, so does the induced voltage, until it reaches a point of equilibrium where the inductor holds the current at a limiting level.
