Fixed Inductors: MLF2012A3R9KT000

Fixed inductors are an important component of electronic equipment in a wide variety of applications, such as power supplies, automotive systems and embedded systems. The MLF2012A3R9KT000 fixed inductor is a surface-mount device (SMD) model produced by TDK. It is usually classified as an under-mounted ceramic inductor. In this article, we will discuss the applications and working principle of the MLF2012A3R9KT000 surface-mount fixed inductor.

Applications

The MLF2012A3R9KT000 surface-mount fixed inductor is used in various applications due to its compact size and high performance. It can be used in Voltage Regulators, DC to DC converters, Battery Chargers, and other power systems. It can also be used as a filter, for impedance matching for improved signal sensitivity, and for EMI suppression. Additionally, the MLF2012A3R9KT000 is especially suitable for automotive applications as it can handle high temperature and vibration levels.

Working Principle

An inductor is a passive electrical component that stores energy in the form of magnetic fields. The MLF2012A3R9KT000 is a reactive component that is made up of a coil of wire wrapped around a core material like air, ferrite or even iron. This coil of wire is a conductor, which allows electric currents to pass through it, creating a magnetic field. When a voltage is applied across the inductor, a current will flow through it. This current creates a magnetic field, which builds up until a saturation point is reached. At this point, the increasing magnetic field induces an opposing voltage, which acts to reduce the current. This is known as the inductive reactance, or the resistance of the inductor to changes in current. The MLF2012A3R9KT000 fixed inductor has a small size and a high impedance, making it suitable for numerous applications.The MLF2012A3R9KT000 is designed to provide reliable and high performance in a variety of conditions and in tough environments. It features a low-loss/ low inductance design combined with high stability and a stable inductance over a wide temperature range. It also boasts a high surge current capability and an easy to assemble surface mount package. The MLF2012A3R9KT000 can also withstand high mechanical shock and vibration and can be used at temperatures up to 125°C.

Conclusion

In summary, the MLF2012A3R9KT000 fixed inductor is a useful surface mount component for a wide variety of applications, such as Voltage Regulators, DC to DC converters and Battery Chargers. It can be applied in automotive systems due to its ability to withstand high temperature and vibration levels. It is also capable of delivering reliable and high performance in a compact size with a high impedance. The MLF2012A3R9KT000 has a low-loss/ low inductance design combined with high stability and a stable inductance over a wide temperature range.
