Fixed Inductors

A fixed inductor is a passive two-terminal electrical component used to provide a known inductance in an electronic circuit. It is made of a coil of copper wire, shells, cores of ferrite or iron, and ferris around a core. Designed to block the direct current while allowing the alternating current, the inductor is widely used in applications such as power supplies and filters.

Working Principle

The B82477R4154M100 operates on the principle of electromagnetic induction. As an alternating current (AC) passes through a coil of wire, the magnetic field produced by the coil induces a voltage in the coil due to the changing magnetic field. This voltage is known as the induced voltage. This induced voltage is an electrical signal, and the inductance of the inductor is determined by the number of coils in the inductor and the distance between the coils. The closer the coils, the greater the inductance. For this particular inductor, the inductance can range from 10uH to 47uH.

Conclusion

The B82477R4154M100 is a medium current inductor used in a wide range of applications. It operates on the principle of electromagnetic induction, where an alternating current is passed through a coil of wire which produces a magnetic field. This magnetic field induces a voltage into the coil which is the basis for the inductance of the inductor. With a maximum current rating of 4.2A, an operating temperature range of -40°C to 125°C, and a wide range of inductance values, the B82477R4154M100 is an excellent choice for various applications.
