Fixed inductors are devices that induce electric currents in electrical circuits and can absorb and store energy when required. Their operational characteristics, largely determined by their construction, include the ability to switch between different winding configurations and the ability to match different capacitance values. MLF2012DR47MTD25 is an example of a fixed inductor which is built with surface mount technology and is designed to be used in a wide variety of applications.

The MLF2012DR47MTD25 fixed inductor is rated for up to 47 µH with a tolerance of ±10% and has a current rating of 1.05 A at 100 kHz, at 55°C. The DC resistance is 11 mΩ and the inductance range is from 40 to 130 µH. It has an operating temperature range of -55°C to +125°C. It is constructed with a high temperature ceramic housing with a metalized alumina internal core, and is packaged in a 2 by 2 mm form factor. It is designed to function in high frequency circuit designs up to 100 kHz and is ideal for general-purpose power-supply circuits.

The working principle of the MLF2012DR47MTD25 fixed inductor is based on its ability to induce a voltage when it is exposed to an alternating current. This voltage, which is determined by the inductance of the inductor, can be used in various ways in electrical circuits, such as in power supply and filtering applications. The filtering can be used to remove noise from a signal, either by blocking certain frequencies or passing only specific frequencies, depending on the type of filter used.

In power supply applications, the MLF2012DR47MTD25 fixed inductor can be used in a switched-mode power supply, or SMPS, circuit. Such circuits use the voltage created by the inductor to charge a capacitor, while also allowing for the switching of the AC input voltage from the power source. By switching AC input on and off at specific intervals, the capacitor can be charged and discharged to produce the desired supply voltage.

The high temperature ceramic housing of the MLF2012DR47MTD25 fixed inductor allows for increased temperature stability in high temperature circuit applications. This helps to ensure the low losses necessary for high frequency operation. Additionally, the form factor of the MLF2012DR47MTD25 fixed inductor allows for easy installation in a variety of tight spaces – its small size and low profile make it ideal for use in power supply circuits in portable devices.

The MLF2012DR47MTD25 fixed inductor is suitable for a wide variety of applications, including power supplies, filtering circuits, DC-DC converters, motor drives, and energy storage. It can be used in general purpose, low voltage, high frequency, and high temperature applications where a high level of noise reduction is required. This makes it an excellent choice for a variety of power-supply applications, especially in portable devices.
