Introduction to the RLF7045T-4R7N2R5-D Fixed Inductor

The RLF7045T-4R7N2R5-D fixed inductor is a high efficiency and high quality part designed for use in many different types of applications. It is a low profile, shielded, ferrite core inductor that is characterized by its low DC resistance. This allows it to be used in applications where low DC resistance is essential, such as power supplies, switching regulators, and LED drivers.

Application Field

The RLF7045T-4R7N2R5-D is well suited for use in the switch mode power supply applications. Its low DC resistance and high saturation current makes it ideal for applications where high efficiency and minimal voltage losses are essential. It can also be used for filtering and EMI suppression applications.The RLF7045T-4R7N2R5-D can be used in a wide variety of applications ranging from consumer electronics to industrial and military applications. It is often used in the motor control applications as the DC link choke for the intermediate bus. Additionally, it can be used in the grid-tie DC-AC inverters as a boost inductor to reduce the input voltage ripples.

Working Principle

The RLF7045T-4R7N2R5-D works by blocking the direct current while allowing the alternate current to pass through. This effect is accomplished through the use of the ferrite core and the inductance of the core. The ferrite core has a high permeability, which allows it to attract the lines of magnetic flux associated with an alternating current and provide a path for the current.The RLF7045T-4R7N2R5-D inductor is also used in the buck regulator applications. The inductor is responsible for storing energy in the form of a magnetic field, which is then released when the switch is opened. This releases the stored energy and helps reduce the voltage ripple along with providing a smooth output voltage.

Conclusion

The RLF7045T-4R7N2R5-D fixed inductor is a quality part designed for many different applications. Its low DC resistance and high saturation current make it suitable for use in switch mode power supplies and other applications. It can also be used for filtering and suppression applications. Its working principle is based on blocking the direct current while allowing the alternating current to pass through. It is also used in buck regulator applications and stores energy in the form of a magnetic field and helps reduce voltage ripple and provide a smooth output voltage.
