Fixed inductors are the most basic type of inductor. They consist of a coil of wire that is wound around a core material, such as iron or ferrite. The core material helps the inductor store magnetic energy, which is then released back into the circuit when the current reverses directions. The inductance of a fixed inductor is determined by the number of turns in the coil, the core material, and the size of the core. One of the most popular fixed inductors is the LQM18NN1R8K00D, which is typically used in power supplies, amplifiers, and other high-current applications.

The LQM18NN1R8K00D is a two-pin, low profile, surface mount fixed inductor with a max inductance of 1.8uH. It has a current rating of 1.8A and an operating temperature range of -40 to +125 degrees Celsius. The device is made of a ferrite material with a copper wire winding, and features a 20% tolerance. It has an insulation resistance of 1000 mOhm and surge current of 3.6A.

The LQM18NN1R8K00D is typically used for circuits that require an inductor with high current and inductance ratings, such as power supplies, audio amplifiers and switching power supplies. This device is also used in applications that require multiple layers, such as switch mode power supplies and medium-current buck converters. In these applications, the LQM18NN1R8K00D\'s small size and low profile make it ideal for use in multilayer circuit designs. Additionally, its 20% tolerance makes it ideal for use in precision circuits.

The working principle of a fixed inductor is relatively simple. When a current passes through a coil of wire, a magnetic field is created around the coil. This magnetic field creates a force that opposes the current\'s direction, resulting in an inductive reaction. This reaction is known as inductance. In the case of the LQM18NN1R8K00D, the inductance is determined by the number of turns in the coil, the core material, and the size of the core. By increasing the number of turns in the coil or the size of the core, the inductance of the inductor can be increased. Conversely, by decreasing the number of turns or the size of the core, the inductance can be decreased.

The LQM18NN1R8K00D is a highly versatile fixed inductor. With its small size, high inductance, high current rating, and 20% tolerance, it is perfect for a wide variety of applications. From power supplies to switch mode power supplies and medium-current buck converters, this device is highly reliable and efficient. With its simple working principle and consistent performance, the LQM18NN1R8K00D is an excellent choice for any application that requires a reliable inductor with a high current and inductance rating.
