Fixed inductors are components designed to store energy in magnetic fields that are constant even with changing current. The 2474R-12L is a specially designed fixed inductor that is used in a variety of applications, depending on the application’s requirements and the current and voltage operating ranges. Understanding its working principle and the application field it covers can help designers in their selection process and use of the 2474R-12L in their projects.

The 2474R-12L is a ferrite core inductor, which basically consists of a ferrite core and a coil of wire wrapped around the core. The core material increases the inductance of the coil and increases the saturation flux density, which makes it ideal for high current applications. It is designed to operate in the frequency range of 1MHz to 100MHz. The 2474R-12L is rated for an inductance range of 0.4uH to 4.7uH with DC resistance values ranging from 2.10 mΩ to 19.65 mΩ depending on the inductance chosen. It has a rated current that goes up to 15A and a recommended voltage of up to 600V.

The working principle of the 2474R-12L is based on the electromagnetic induction principle. Electromagnetic induction is based on the concept of a changing current loop that creates an electromagnetic field, which in turn induces a voltage in a nearby coil. In the 2474R-12L the electromagnetic field of the current loop interacts with the ferrite core material. This causes the core material to become magnetized and create a magnetic field, which in turn increases the inductance of the coil. As the current changes, the magnetic field also changes; which, according to Faraday’s law of induction, in turn induces a voltage in the coil.

The 2474R-12L is used in a variety of application fields. It is used in the power conditioning circuits, especially in switching power supplies where it acts as a filter inductor, to reduce the level of ripple and noise caused by switching of the power devices. It is used in Atmel AVR microcontrollers for voltage regulation and filtering of the power supply. It is also used in high current circuits such as high current automotive circuits. Additionally, it is used in pulse applications as the ferrite core material increases the inductance and makes the inductor suitable for high current pulses.

In conclusion, the 2474R-12L is a ferrite core inductor with a range of rated inductance and resistance values. It operates in the frequency range of 1MHz to 100MHz. It is rated for 15A of current and 600V of voltage. Its working principle is based on the electromagnetic induction principle, where a changing current loop creates a magnetic field which in turn induces a voltage into the coil. The 2474R-12L has applications in high current circuits, pulse applications, power conditioning circuits and voltage regulation and filtering in microcontrollers.
