What Are Fixed Inductors?
Fixed Inductors, also known as inductors or coils, are electrical components used to create a magnetic field when current is passed through them. The two main types of fixed inductors are axial and radial. Axial inductors are typically a cylinder shape while radial inductors are typically wire-wound on a frame.

The CR75NP-391KC Application Field and Working Principle
The CR75NP-391KC fixed inductors are axial components, typically in a cylinder shape, manufactured by Nippon Chemi-Con. They have a rated inductance of 390 nH and an operating temperature range of -40°C to 85°C. The CR75NP-391KC inductors are designed for high-frequency applications, making them ideal for high-frequency power converters, DC voltage steps, and DC-DC converters.

The working principle of the CR75NP-391KC fixed inductors is based on Faraday’s Law of Induction. When a current is applied to the inductor, it creates an opposing magnetic field, in this case, a rotating magnetic field. This field opposes the flow of the current, creating a voltage in the inductor. The magnetic field created by the inductor is proportional to the amount of current flowing through it. This opposing magnetic field causes a voltage increase in the inductor, as well as a voltage decrease across the inductor.

The CR75NP-391KC fixed inductor has a winding resistance of 0.3 ohms and an inductance range of 390 nH. The inductance is what directly affects the amount of current flow in the inductors, as the more current that flows through the inductor, the higher the inductance. The CR75NP-391KC fixed inductor is designed for high-frequency applications, so it has an increased inductance value for higher frequency applications.

Applications
The CR75NP-391KC fixed inductor is ideal for high-frequency power converters, LED controllers and DC-DC converters, as it has a low DC resistance and increased inductance for higher frequency applications. It is also used for filtering noise in signal lines, supercharging, and creating RF filters.

Conclusion
In conclusion, the CR75NP-391KC fixed inductor is a cylindrical inductor manufactured by Nippon Chemi-Con. It is designed for high-frequency power converters, LED controllers and DC-DC converters, as it has a low DC resistance and increased inductance for higher frequency applications. It is also used for filtering noise in signal lines, supercharging, and creating RF filters.
