Fixed inductors, such as the ELL-3GM2R7N, are electronic components typically used in the fields of telecommunications, consumer product, automotive and medical device industries. They are commonly used to maintain or adjust electric currents for many different applications, such as for transforming energy, regulating voltage levels and providing stability to power supplies. In this article we will be focusing on the application field and working principle of the ELL-3GM2R7N fixed inductor.

The ELL-3GM2R7N fixed inductor is primarily used in applications related to power, such as in power supplies, DC/DC converters, general-purpose amplifiers and onboard power systems. It is also often used in applications that require a high inductance, such as DC-DC converters with high-frequency switching, or as an inductor for high-frequency switching. In some cases, the ELL-3GM2R7N is used in high attenuation DC/DC converters for improved power efficiency.

The ELL-3GM2R7N is a 3-terminal fixed inductor that features a ferrite core and a composite winding. The inductance value of the component is 2.7 μH and it can withstand operating temperature ranges from -15℃ to +100℃. It has a high saturation current of 12.5 A and a maximum DC resistance of 0.36Ω. The ELL-3GM2R7N is able to provide a high-frequency response up to 10 MHz, with a Q factor of 8.5 at 1.6 MHz.

The working principle of the ELL-3GM2R7N involves its two terminals and the internal magnetic field. When current is passed through the inductor, a magnetic field is created within the coil. This magnetic field creates a temporary storage or back EMF when the current is interrupted, which counteracts the change in current and helps to stabilize the current passing through the inductor. When the current is increased, the generated magnetic field prevents further increase of the current, thus limiting it. The magnitude of the stored EMF is proportional to the rate of change of current, which means that it is more effective at limiting rapidly changing AC currents.

The ELL-3GM2R7N fixed inductor has several advantages, such as its high inductance value at low frequencies, low DC resistance and high saturation current. It is also designed for high-frequency applications with a high-quality factor of 8.5 at 1.6 MHz. Furthermore, the ELL-3GM2R7N is able to withstand a wide operating temperature range, making it an ideal choice for a variety of applications.

In summary, the ELL-3GM2R7N fixed inductor is a versatile and reliable component suitable for many different applications, such as power supplies, DC/DC converters, general-purpose amplifiers and onboard power systems. Its working principle involves the generation of an internal magnetic field that produces a back EMF, which counteracts changes in current and helps to stabilize power supplies. The ELL-3GM2R7N has many advantages, such as a high-frequency response, a high Q factor and a wide operating temperature range, making it a suitable choice for a variety of applications.
