Fixed inductors are common electronic components. They are cylindrical or disk-shaped inductors that are composed of coils and magnetic cores. They are used to store electrical energy and establish inductance in electrical circuits. A common type of fixed inductor is 103R-472F. This paper will discuss the application field and working principle of the 103R-472F inductor.

103R-472F Application Field

The 103R-472F inductor is a popular choice for use in low voltage, low frequency applications. In particular, it is commonly employed in the circuitry of televisions, radios, amplifiers, computers, telephones, power supplies, and other electronic devices. It is also used in the production of air conditioners, microwave ovens, and other electrical appliances.

The 103R-472F inductor generally has a maximum working voltage of 68V DC, a maximum working current of 4.72A, and an inductance of 1.0 μH. It can withstand temperatures ranging from -20℃ to +125℃, and its size is only 6.3x10.35mm. This small size makes it easy to install in many different types of equipment, and makes it ideal for use in compact, high-density circuitry.

Working Principle

The working principle of a fixed inductor is based on the basic law of electromagnetism, known as Faraday\'s Law of Induction. According to this law, a changing magnetic field that passes through a closed loop of conducting wire will induce an electric current in the wire. This induced electric current then creates a magnetic field, which interacts with the original magnetic field. This interaction can store energy in the form of a magnetic field, as is the case with an inductor.

When an electric current passes through a 103R-472F inductor, its coils create a magnetic field around the inductor\'s core material. This magnetic field builds up over time, storing energy. When the electric current is stopped, the stored energy is released in the form of a reverse electric current. This reverse current ensures that the load of a circuit remains constant, even when the current is turned off.

Conclusion

The 103R-472F is a widely used fixed inductor that is suitable for use in a range of low voltage, low frequency applications. Its small size and durable construction make it ideal for use in the circuitry of electronics and electrical appliances. Its working principle is based on Faraday\'s Law of Induction, which states that a changing magnetic field passing through a closed loop of wire will induce an electric current in the wire. This electric current then creates a secondary magnetic field that is capable of storing energy, as is the case with an inductor.
