Fixed inductors are electronic components that serve as a common form of energy storage and energy transfer in a variety of electric and electronic circuits. This article will focus specifically on the ELL-4GG2R2N, outlining its application field and working principle.

What is the ELL-4GG2R2N?

The ELL-4GG2R2N is a fixed inductor that is used as a general-purpose power inductor for DC power line. It is characterized by having a high current rating up to 11A, comprehensive impedance match with the DC power line voltage, low DCR to reduce losses, and a relatively high inductance. The ELL-4GG2R2N is also available in various sizes and configurations, allowing for specialized applications.

Application Field

The ELL-4GG2R2N is used in a variety of applications, the primary ones being for electrical current filtering, voltage regulation, and power supply smoothing. The inductor is also used for LED dimming, as well as for pulse width modulation. Additionally, due to its resistance to heat, the ELL-4GG2R2N can also be used in high-temperature environments.

Working Principle

The ELL-4GG2R2N works by storing energy in the form of a magnetic field. This is made possible by passing a current through the inductor\'s winding coil. This current moves in a single direction, which creates a magnetic field. This field experiences a force called the \'electromotive force,\' which builds the current until it reaches a particular level. This stored energy is then released by reversing the current direction, thus creating an opposite and weaker magnetic field.

The stored energy is also released when the current is subjected to a sudden decrease or increase. If the current is rapidly decreased, the magnetic field will collapse and cause the inductor to produce a voltage that opposes the change. This is known as \'back EMF\' and is used by the inductor to help regulate current and voltage levels. On the other hand, if the current is quickly increased, the magnetic field will grow exponentially and cause the inductor to produce an over-current, again helping to regulate current levels.

Conclusion

The ELL-4GG2R2N fixed inductor is a reliable and versatile electronic component that is used in a variety of applications. It primarily functions by storing electrical energy as a magnetic field, and this stored energy is released when the current is subjected to sudden changes. Additionally, the ELL-4GG2R2N has a high current rating and a high inductance, making it an ideal choice for a variety of applications.
