NRS8040T4R7NJGJ Inductors, Coils, Chokes

Fixed inductors are types of electronic components comprising a core surrounded by a winding coil, typically consisting of many turns of wire. The core keeps the windings in place, structurally and magnetically, while the coil is used to store energy, which can be used to induce a current in another component in a closed circuit. The capacity of the coil is expressed by the term “inductance” which is measured in units of “henries”. Fixed inductors are used in a variety of applications, ranging from consumer electronics to high-performance medical imaging. One such component is the NRS8040T4R7NJGJ.

Application Field

The NRS8040T4R7NJGJ is a surface-mount fixed inductor that is ideal for power line applications. Its construction features a ferrite core which is highly efficient in preserving energy and reducing distortions caused by external interference. The component offers excellent power and noise characteristics which make it a reliable choice for a wide range of applications. It features an inductance of 8.4 µH with a saturation current of 11.7 A at a relatively low DCR of 0.077Ω. It is available in a range of package sizes from 1.6 x 1.2 mm to 5 mm x 5 mm, with tolerance value of 10%.

Working Principle

Fixed inductors work by utilizing the principle of inductance. This means that as electric current passes through the windings of the inductor, it creates a magnetic field that stores energy. When this current is suddenly disrupted, the energy is quickly released, creating an induced current in the surrounding circuit. This induced current helps to regulate the current passing through the component, helping to reduce interference and noise. For power line applications, like those that the NRS8040T4R7NJGJ is best suited for, this helps to maintain consistent power supply to other devices.

Conclusion

The NRS8040T4R7NJGJ is a high-quality fixed inductor suitable for a wide range of applications that require an efficient, reliable power source. Its construction features a ferrite core and offers excellent power and noise characteristics, along with low distortion of external interference. With a wide range of package sizes available, and a tight tolerance of 10%, this inductor is ideal for power line applications that require superior performance.
