Fixed inductors, also known as iron core inductors, are normally used in several high frequency applications that require high power levels. There is a wide range of fixed inductors available on the market which are used for various applications, depending on their features and specifications. The 103R-391J is a commercial grade sheet wound fixed inductor, and has features and specifications which make it suitable for several different applications.

The 103R-391J has a core material of iron powder and a winding material of copper. It also has a maximum operating temperature of 85°C and a nominal inductance of 390mH. Additionally, the maximum DC current is 0.95 ADCC, and the Q Factor (Q = Inductance divided by Resistance) is 15. The mounting type is lead free solder and the standard tolerance is 20%, with a typical series resistance of 0.3 Ohms.

In terms of applications, the 103R-391J is used in high power transfer applications, especially where there is a requirement for high frequency signal generation. This type of inductor can also be used for both AC and DC operation. Specifically, the 103R-391J can be used for telecommunications, power supplies and electronic appliances, as it offers high power and high frequency. Additionally, the 103R-391J can be used to buffer and filter signals as it has a low series resistance and high Q factor.

The working principle of the 103R-391J is based on the fact that when a wire or conductor passes through a magnetic field, a voltage will be induced in it. This is known as Faraday\'s principle of electromagnetic induction, which states that when a magnetic field is changes, it will generate a current in the wire. In this case, the magnetic field is generated by the core material which is iron powder, and the current is generated in the copper winding. The induced voltage is used to power the equipment or circuit that is connected to the inductor, and this is how the 103R-391J fixed inductor works.

In conclusion, the 103R-391J is a commercial grade sheet wound fixed inductor which is capable of delivering high power and high frequency signals for applications like telecommunications, power supplies and electronic appliances. It is based on Faraday\'s principle of electromagnetic induction, where a changing magnetic field induces a current in a conductor, and this is how it operates.
