Fixed inductors are components of electrical circuits, also known as coils, chokes, or reactors. They are used as filters, transformers, or oscillators in radio, telecommunications, and power electronics applications. The LQM21DN220N00L is an example of a fixed inductor which is especially designed for automotive electronic equipment.

The LQM21DN220N00L is an axial lead snap-in type surface-mount inductor. It comprises a ferrite core and an external magnetic shield, and is ideal for automotive applications due to its high temperature and humidity resistance. However, it can also be used in other applications, such as in power supplies, audio circuits, and antistatic protection, as well as in industries including healthcare and manufacturing.

The LQM21DN220N00L has a rated operating temperature of -40 to 85°C and is available in various voltages and inductance values. It also has an excellent inductance-to-resistance ratio for space-constrained applications. Its rated DC current is up to 10 A and has a surge current of 20 A. It is also RoHS compliant, making it safe for use in the environment.

The working principle of a fixed inductor involves the use of a coil of wire wrapped around a magnetic core. The inductor creates an inductance when current passes through the coil, effectively transforming current into magnetic energy which is then stored in the core. The inductor then dissipates the stored energy back into the circuit in the form of an electromagnetic surge, which helps to regulate the current. Some inductors are designed with an adjustable core, which is used to fine-tune the characteristics of the inductor for specific applications.

Inductors are used in a wide range of applications, from basic electronic circuits to more complex systems such as automotive electronics. The LQM21DN220N00L is a specific type of fixed inductor, designed for use in automotive applications, which is resistant to high temperatures and humidity and is RoHS compliant. Its impressive inductance-to-resistance ratio and durability make it an ideal choice for automotive electronics.
