Fixed inductors, also known as inductive components, comprise of a coil of copper wire wound on an iron core or in air. The B78108S1473J000 is a type of fixed inductor specifically. It is a SMD Inductor designed for SMT applications in consumer electronics, telecommunications, automotive and industrial applications.

It has a compact miniature shielded construction which reduces heat due to its limited size. It is a radial inductor with a resultant inductance of 4.7 µH and a maximum operating frequency of 9.8 kHz. It has a nominal current rating of 0.95 A (any operating current should not exceed this rating) and a DC resistance of 0.027 Ω. The power rating of this transformer is 90 mw.

The working principle of a fixed inductor is based on the self-inductance of a conductor. This phenomenon is described by Faraday\'s law of induction. According to the law, a current-carrying inductor will oppose a change in the current flowing through it as it stores and releases energy in the form of an electromotive force. This electromotive force is commonly referred to as back emf. This back emf is proportional to the rate of change of the current.

The B78108S1473J000 fixed inductor is mainly used in high speed switching and filtering applications because it has lower losses and better temperature stability. It also offers efficient EMI filtering and noise reduction, and has a wide range of applications, including switched-mode power supplies (SMPS), DC-DC converters, resonant circuits, and power amplifiers.

In terms of characteristics, the B78108S1473J000 inductor has a high reliability and excellent workability. It has a low DC resistance and high current capacity which give the inductor a longer working life. It also has a low off-state inductance so it can handle higher frequencies better. Additionally, the high temperature grade and long-term stability of this component makes it suitable for the relatively high-frequency applications like energy storage, automotive electronics, and industrial automation.

In conclusion, the B78108S1473J000 is a type of fixed inductor designed for SMT applications, offering excellent workability, high reliability, and low resistance. It is mainly used in high speed switching and filtering applications, and is suitable for applications like switched-mode power supplies, DC-DC converters, resonant circuits, and power amplifiers. The working principle of it is based on self-inductance of conductors.
