2727R-25J

Fixed Inductors

One type of fixed inductors is the 2727R-25J, which is a power inductor designed to supply current to an integrated circuit or any other component requiring a high level of current. It is a relatively medium power inductor, meaning that it can be used for various applications such as power supplies,audio amplifiers,and microcontrollers.

Application Field

The 2727R-25J is capable of providing current up to 25 amperes, making it well-suited for applications requiring high-current outputs. It is primarily used in power supplies, switching power supplies, DC-DC converters, audio power amplifiers, and microcontrollers. It is also suitable for high-current loads such as microprocessors. Furthermore, the high frequency of the 2727R-25J makes it attractive for automotive applications due to its low EMI. Moreover, due to its low profile, the 2727R-25J is suitable for applications requiring minimal board space.

Working Principle

The 2727R-25J is a form of inductor, which works by storing energy in its magnetic field. This is done by winding a wire conductor around a core material which induces a magnetic field when an electrical current is passed through it. The core material used in the 2727R-25J is ferrite core, which provides a more efficient means of storing magnetic flux. As current is passed through the ferrite core, it expels magnetic fields that induce voltage in the conductor winding. This creates a voltage drop opposed to the current flow. The 2727R-25J is designed so that the voltage drop is reproducible across frequency and temperature ranges, providing a consistent current output.

The 2727R-25J is able to maintain its inductance value over a relatively wide range of temperatures by an optimization technique that uses a combination of core material, wire material, and construction geometry. As with most inductors, the inductance of the 2727R-25J decreases when operated at high temperatures, however, its high-temperature inductance is still significantly higher than those of other inductors.

The 2727R-25J is designed to be used in a variety of circuits and applications. Its low profile makes it suitable for applications that require minimal board space, low profile, and high current output. Its ferrite core and optimized construction provide a stable current output over a wide range of temperatures and frequencies, which is useful for power conversion and regulation.
