Fixed inductors, also known as chokes, are used primarily for suppressing noise or EMI, store energy, and provide paths for electric currents. Grounding and shielding inductors are also part of this category.
The LQP02HQ2N8B02L is a molded power inductor commonly used in automotive and DC-DC buck converter applications, and is part of Murata\'s Power Chip product line. It is made of ferrite-based material and features a metal shield. It has a maximum DC current of 2.2 Amps, and is designed for peak load conditions.

Application Field of LQP02HQ2N8B02L

The LQP02HQ2N8B02L is designed to meet the needs of various automotive and power supply systems. Its main application is in automotive and DC-DC buck converter circuits. In these circuits, it acts as a DC filter for suppressing noise and EMI, reducing power supply ripple, and improving voltage efficiency. It also has the ability to store energy and provide a path for electric currents. Additionally, its high current rating ensures stable power conversion during peak load conditions.

Working Principle of LQP02HQ2N8B02L

The working principle of the LQP02HQ2N8B02L is based on Faraday’s law of induction. When facing an alternating current, this inductor produces magnetic flux. This flux then links to the turns of the winding and induces an electromotive force, or “back EMF”. This back EMF opposes the applied voltage and produces a voltage drop across the inductor’s terminals. This voltage drop helps to reduce the power supply ripple and improve voltage efficiency.

The LQP02HQ2N8B02L also works as a filter circuit. It stores and releases energy in the form of a magnetic field. This energy then works against the input signal. As a result, the end transmitted signal is faster and more efficient. This helps to reduce noise and EMI.

The LQP02HQ2N8B02L also has the ability to provide a path for electric currents. This ensures current flows in the proper direction and also helps maintain an even circuit temperature. This helps preserve the life of the chip’s components.

Conclusion

The LQP02HQ2N8B02L is a molded power inductor specifically designed to meet the needs of automotive and power supply systems. Its application fields include suppressing noise and EMI, reducing power supply ripple, and improving voltage efficiency. The working principle of the inductor is based on Faraday’s law of induction. This helps ensure stable power conversion during peak load conditions and helps preserve the life of the inductor’s components.
