Fixed Inductors
Inductors are components that store electrical energy in the form of a magnetic field and whose primary function is to oppose any change in the current passing through it. Fixed inductors are components whose inductance is fixed and not subject to external influence or control. The 79F1R8K-TR-RC is a common inductor that is widely used in the electronics industry.
Application Field
The 79F1R8K-TR-RC is a small, axial leaded, lowprofile, broadband ferrite bead inductor with self-resonating operation modes. Its primary applications are in the telecom, consumer, medical, automotive, and industrial segments. In telecom, for example, it may be used to filter and suppress various undesired signals, including high-frequency RF emissions. It is a common component used in amplifiers, switches, and DC-DC converters, as well as in communication and signal-conditioning circuits. In consumer applications, the 79F1R8K-TR-RC is often used in noise-suppressing filters, RF-ID systems, and in automotive DC-DC converters, motor controllers, voltage regulators, and noise-eliminating circuits.
Working Principle
The 79F1R8K-TR-RC uses a ferrite bead-type inductor, which is composed of two or more wire coils wound around a ferrite core. This core provides both inductive and capacitive reactance properties, giving the inductor a low inductance at high frequencies, and a high inductance at low frequencies. As a result, it acts as a lowpass filter that allows only low-frequency signals to pass through. This filtering effect is used to suppress undesired high frequency noise from the circuit while allowing the desired signal to pass.
When a signal passes through the 79F1R8K-TR-RC, the current from the signal induces an opposing magnetic flux in the core of the inductor, thereby forming a transformer of sorts. This transformer operation reduces the amplitude of the signal and attenuates the high frequency components, thus reducing the amount of noise present in the circuit. The resulting output is a signal with a lower level of high frequency noise compared to the input.
The 79F1R8K-TR-RC is also known as a broadband ferrite bead inductor because it can provide effective suppression of high-frequency noise with minimal effect on the desired signal. This makes it an ideal choice for applications that require noise suppression and signal conditioning.
In conclusion, the 79F1R8K-TR-RC is a versatile fixed inductor that can be used in many different applications requiring noise suppression and signal conditioning. It is a small, low-profile, yet effective component that is widely used in the electronics industry.
