Fixed inductors are a type of inductor that stores energy within it in the form of a magnetic field. In most cases, fixed inductors are used in combination with capacitors or resistors to form tuned circuits and filtering circuits. One of the most commonly used fixed inductors is the LQH66SN100M03L, which is a type of shielded power inductor.

The LQH66SN100M03L is a surface-mount inductor that is widely used in DC-DC converters for laptop computers, tablets, and other handheld electronics. It is composed of a ferrite core surrounded by two coils of copper wires. This inductor is rated to handle a maximum of 100 mA with an inductance of 66 uH, and its operating temperature range is between -25 and 85 Celsius. The LQH66SN100M03L has a time-constant of 7 µs, which makes it ideal for applications requiring low-noise power switching.

The working principle of the LQH66SN100M03L is based on the fact that when a current passes through a conductor, it creates a magnetic field. This magnetic field then interacts with the core of the inductor, causing a secondary current to be generated. This secondary current is what is responsible for creating the inductance effect, which makes it ideal for DC-DC converters. The disadvantage of using an inductor is that the current must be passed through it continuously, or else the energy stored in the inductor will be lost.

The LQH66SN100M03L is a very useful inductor for low-noise, power-switching applications. It has a high current carrying capacity, a wide temperature range, and an excellent time-constant, which make it a great choice for many mobile device applications. This inductor is also widely used in power supply, DC-DC converter, and filtering circuits.

In conclusion, the LQH66SN100M03L is a fixed inductor that is often used in DC-DC converters, power supplies, and filter circuits. It works by creating a magnetic field when a current passes through it, and this magnetic field is what creates the inductance effect. This inductor is characterized by its high current carrying capacity, wide temperature range, and excellent time-constant, which make it a great choice for a variety of low-noise, power-switching applications.
