Fixed inductors are electronic components which store electrical energy in the form of a magnetic field when current flows through a coil. They are often used in the field of electronic circuits, such as portable audio equipment, voltage regulators, power converters, and more. Fixed inductors usually come in a variety of sizes and shapes, and are also known as inductor coils, or simply coils.

79F151K-TR-RC is a type of fixed inductor manufactured by EIC Co., Ltd. It has a maximum DC current rating of 8.2A and is commonly used in LED lighting applications.

79F151K-TR-RC is mainly used in DC/DC converters and LED lighting circuits. It is a surface-mount, non-shielded type inductor with a tolerance of ±10%. It is constructed of ferrite core material, which makes it resistant to corrosion, heat, and humidity.

The working principle of 79F151K-TR-RC is quite simple. When current flows through the inductor, it magnetizes the core and also creates an opposing magnetic field. This opposing magnetic field generates a voltage across the inductor, which opposes the current. As a result, a voltage drop is produced across the inductor. The magnitude of the voltage drop is proportional to the amount of current flowing through the inductor.

It is important to note that an ideal inductor does not dissipate any energy and, therefore, it has a zero resistance. However, in a real inductor like the 79F151K-TR-RC, some power is dissipated due to the resistance of the core material. This is known as the “loose inductance” effect.

The 79F151K-TR-RC has an inductance of 1.5µH and a continuous current rating of 0.85A. In addition, it has a rising and falling edge current rate of 1.2A and 2A respectively. It also has a saturation current rating of 8.2A, which means that it can handle large peak currents without being damaged.

The 79F151K-TR-RC is a very versatile and reliable component that can be used in a wide range of applications. It is commonly used in battery-powered devices, automotive electronics, LED drivers, monitor circuits, LED string circuits, and many other circuits where reliable inductance and voltage drop are required.
