Introduction

Fixed inductors are one type of components, which are mainly used in various electronic circuits. They function as devices that store electromagnetic energy in the form of magnetic flux. In simpler terms, they are an inductor with a fixed inductance rating. Fixed inductors are commonly used in power supplies, dc-dc converters, audio amplifiers, oscillators and radio-frequency filters.The MLF2012A2R2MTD25 is a fixed inductor from TDK Corporation, which is a leading electronics component manufacturer based in Japan. This fixed inductor is specifically designed for use as a device that can convert AC current into DC current.

Application Field

The MLF2012A2R2MTD25 is designed for use as an AC-DC power supply device. It is primarily used in applications such as uninterruptible power supplies (UPS) and other low-frequency circuits. It is capable of converting AC current into DC current and has a rated power of 2W with an operating temperature of -40°C to +125°C.The MLF2012A2R2MTD25 has a usable range from 25kHz to 1MHz and a total of 1.2A of current at 27kHz. It is capable of handling up to 3A of peak current with a peak of 87mA at 27kHz. This makes the MLF2012A2R2MTD25 particularly suitable for use as an AC-DC power supply device in applications such as UPSs, chargers and other low-frequency circuits.

Working Principle

The MLF2012A2R2MTD25 utilizes the concept of induction to convert AC current into DC current. Induction is the physical phenomenon where a changing magnetic field generated by an alternating current induces voltage in a conductor. This is due to the principle of Faraday\'s law of induction, which states that a changing magnetic flux through a circuit induces an electromotive force (EMF) within the circuit itself.The MLF2012A2R2MTD25 works by using alternating current to create a magnetic flux in the inductor. This magnetic flux then induces an EMF within the inductor, which is proportional to the rate of change of the flux. This induced EMF is then rectified by a diode to convert the alternating current to direct current.

Conclusion

The MLF2012A2R2MTD25 is a fixed inductor from TDK Corporation that is designed for use as an AC-DC power supply device. It utilizes the concept of induction to convert AC current into DC current and has a rated power of 2W with an operating temperature of -40°C to +125°C. The MLF2012A2R2MTD25 is particularly suitable for use in applications such as UPSs, chargers and other low-frequency circuits.
