Introduction

Fixed Inductors are electronic components that are designed to supply consistent voltage and current to their respective circuits. Among the most commonly used for this purpose is the LQW18AN33NG80D, an inductor characterized by its high efficiency and precision.

Application Field and Working Principle

The LQW18AN33NG80D is most commonly used in circuits that require precise current control and low ripple. It is highly suitable for high-frequency switching applications, such as in DC-DC converters, to limit the peak current passing through the circuit. The inductor is usually connected between the switch and output of a circuit, which functions to reduce the current ripple by acting as a load or storing energy in a magnetic field.

The working principle behind the LQW18AN33NG80D is based on Faraday’s Law of Induction. This law states that when a conductor is exposed to a changing magnetic field, a voltage will be induced in the conductor. The LQW18AN33NG80D takes advantage of this phenomenon by inducing an opposing voltage across its coil, which results in limiting the current passing through the circuit.

Design and Features

The LQW18AN33NG80D is designed with a magnetically shielded ceramic body for maximum protection. It has a small size, measuring just 18 mm in diameter, and a low profile height of just 6.7 mm. This feature makes it highly suitable for applications where space is limited. The inductor is also equipped with a solderable termination for easy installation.

The LQW18AN33NG80D has an inductance range of 1.3 to 33 nH and a rated current of 500 mA. Additionally, it has a very low DC resistance of just 1.3 Ohms, making it suitable for high frequency applications. The inductor is also equipped with a rated self-resonant frequency of up to 400 MHz, allowing for improved efficiency when switching.

Conclusion

The LQW18AN33NG80D is an ideal choice for electronic high-frequency switching circuits that require precise current control and low ripple. It is highly suitable for applications where size and space are at a premium. Moreover, its magnetically shielded ceramic body provides maximum protection from external interference. The LQW18AN33NG80D is designed with an inductance range of 1.3 to 33 nH, a rated current of 500 mA, and a self-resonant frequency of up to 400 MHz, allowing for improved efficiency.
