Fixed inductors are a type of electronic component used in circuits that control the flow of direct current or alternating current in circuits. The 79F181K fixed inductor is a type of inductor developed by Nippon Electronic Company (NEC) in 1985. It is a high frequency inductor, capable of handling up to 200 MHz. The 79F181K is designed for applications such as high power supplies, switch mode power supplies (SMPS) and other high frequency circuits.

The 79F181K consists of a magnetic core made of ferrite material with two coils of wire wound around it. The assembly is encased in a plastic housing to provide protection and insulation. A ferrite core can provide higher inductance than an air core, which is mainly because when a current is passed through the ferrite core, it produces a magnetic field that interacts with the current. This interaction increases the inductance of the component.

The 79F181K has a wide operating frequency range, giving it a wide range of possible applications. It can be used in high-frequency circuits such as radio frequency (RF) communications, high-speed analog-to-digital (A/D) converters and high-power switching circuits. It can also be used in switched-mode power supplies (SMPS), such as in laptops and other electronic devices.

The 79F181K has a rated inductance of 1.8 mH, with a maximum operating current of 1.74A. It has a current impedance of 0.41 ohm and a high frequency impedance of 6 ohm. The 79F181K also features a maximum DC resistance of 0.112 ohm, which is important in high current circuits. The inductor\'s operating temperature range is -40°C to 85°C, making it suitable for use in a wide variety of environments.

The 79F181K fixed inductor is a versatile component that can be used for a wide variety of applications. It is useful in high-frequency circuits where a high inductance and high frequency performance are required. It can also be used in switched-mode power supplies for efficient power management.

As a high frequency inductor, the 79F181K provides excellent performance with its high inductance and low resistance, allowing it to handle high operating frequencies and high current demands. It is well suited to a variety of applications, such as RF communications, high-speed analog-to-digital converters and high-power switching circuits.
