Fixed Inductors are efficient components in electronic circuits, used to store electrical energy and provide signal filtering. They are simple, efficient and convenient to use and can be found in a variety of consumer electronic devices. The CR75-391KC is a fixed inductor designed for a range of applications. This article will discuss the application field and working principle of the CR75-391KC.

The CR75-391KC is an off-the-shelf, surface mount, metal-core inductor designed for use in local board level wireless telecommunication systems. It is typically used in power amplifiers, signal or frequency filters, antennas or for matching impedance in certain circuits. The CR75-391KC is characterized by its low current leakage, low insertion loss and high Q value. The CR75-391KC can be used in a wide frequency band from 800 MHz to 1.2 GHz.

The CR75-391KC consists of an iron powder core wrapped with winding wire, and a shielding cover which helps to suppress unwanted noise. The inductor is designed to reduce the signal\'s high frequency harmonic content while allowing the lower frequency signals to pass. It is also effective for impedance matching, allowing the correct impedance to be maintained in order to optimize signal quality.

The working principle of the CR75-391KC is that it stores electrical energy in a magnetic field created by its iron powder core. This magnetic field varies depending on the frequency and amplitude of electric current which passes through the winding wire in the core. It reduces the high frequency harmonic content of the signal, while allowing lower frequency signals to pass. The inductor also prevents the current from exceeding the established levels as it passes through the circuit, which is why it is used for impedance matching in certain circuits.

In conclusion, the CR75-391KC is an off-the-shelf, surface mount, metal-core inductor designed for a range of applications. It is an efficient component for filtering signals, matching impedance, and controlling the current in a circuit. The inductor stores electrical energy in a magnetic field created by its iron powder core, and reduces the signal\'s high frequency harmonic content while allowing lower frequency signals to pass.
