Fixed inductors are electronic components used for inductive purposes, such as creating a frequency-dependent voltage by magnetic induction or storing energy as a magnetic field. The 78F2R7K-RC is a fixed inductor, primarily used for power supply filtering, power factor correction, and common-mode filter applications. Although the physical size and properties of the 78F2R7K-RC are similar to those of other fixed inductors, there are some key differences in application fields and working principles that set it apart.

Application Fields

The 78F2R7K-RC is a very versatile inductor, with many possible applications. Its primary usage is for power supply filtering, power factor correction, and common mode filter applications.

For power supply filtering, the 78F2R7K-RC can be used to control the AC and DC components of the power supply, eliminating unwanted ripple. This application is particularly useful in AC-DC power converters, where a smooth power supply is required.

For power factor correction, the 78F2R7K-RC can be used to control the phase of the alternating current, reducing the frequency of the waveform and improving the power factor of the system. This is particularly important in low-voltage applications, such as computers and televisions.

For common mode filter applications, the 78F2R7K-RC can be used to filter out high-frequency noise, such as from power lines or other sources of interference. This is important as the presence of noise can affect the performance of the system, or cause damage to the equipment.

Working Principle

A fixed inductor is a component that works on the principle of electromagnetic induction. When electric current passes through an inductor, a magnetic field is created around the inductor. This magnetic field stores energy, and when the current is stopped, the stored energy is gradually discharged. This is known as “inductive reactance”, and is measured in ohms. The value of the inductive reactance is directly related to the inductance of the inductor.

The 78F2R7K-RC is a custom-made inductor, designed to be used in a wide range of applications. The inductance of the component is rated at 2.7uH at 10MHz, and the current and temperature ratings are 360mA and 125°C, respectively. The size of the 78F2R7K-RC is 12.5mm x 9.5mm x 10mm, which makes it perfect for use in space-constrained applications.

Conclusion

The 78F2R7K-RC is a custom-designed fixed inductor, ideal for a wide range of application fields. It can be used for power supply filtering, power factor correction, and common-mode filter applications, and its small size and stable performance make it the perfect choice for space-constrained systems. The 78F2R7K-RC works on the principle of electromagnetic induction, where electric current creates a magnetic field around the inductor, and the inductance of the component is determined by the value of the inductive reactance.
