Fixed inductors, also known as coils, are components commonly used in electrical systems. They are commonly used for filtering, smoothing, or resonating electrical signals, depending on their specific application. Among the various types of fixed inductors, the LQW18AN68NJ00D stands out as one of the most powerful and efficient on the market. Here, we will look at the application field and working principle of the LQW18AN68NJ00D.

The LQW18AN68NJ00D is a high-power, high-efficiency, low-profile inductor, designed for applications requiring high peak currents. It incorporates a ferrite-core material, and is typically used in automotive, consumer, and computer applications. By utilizing ferrite-core material, the LQW18AN68NJ00D inductor experiences a minimized core loss and higher saturation current. Additionally, the footprint of the LQW18AN68NJ00D is very small, reducing the volume of the printed circuit board. This makes it an ideal choice for portable electronics where space is a concern.

The LQW18AN68NJ00D inductor is typically used in power supply filtering and in LC oscillator circuits. Its high power handling capability and low noise output make it an ideal choice for these applications. In power supply filtering, it helps to reduce high-frequency ripple and provides power output stability. In LC oscillator circuits, the LQW18AN68NJ00D provides the desired oscillation frequency, enabling the circuit to oscillate when a resistor and capacitor are connected in series across the inductor. The inductor also reduces high-frequency noise generated in such circuits.

The LQW18AN68NJ00D works on the basic principle of induced current. When a current is passed through a coil, an electromotive force, or emf, is generated in the coil. This generated emf is known as self-induction. When the current passes through the coil, it generates an opposing emf that is proportional to the rate of change of current. This opposing emf acts to reduce the flow of current in the coil. This occurs because the change in magnetic field creates an inductive reactance which opposes the flow of current.

The inductance of the LQW18AN68NJ00D is specified at 18 nH, with a DC resistance of 0.128 mΩ. This inductance can be varied by manipulating the number of turns in the coil, or by adjusting the core material. The size and shape of the inductor also affects the inductance. As a general rule, larger coils will have greater inductance than smaller coils.

The LQW18AN68NJ00D inductor is an extremely versatile component which is suitable for a wide variety of applications. Its high peak current handling capability and low noise make it a valuable addition to a variety of circuits. By understanding the application field and working principle, it is easy to take advantage of its full potential.
