Fixed Inductors

A fixed inductor, or fixed coil, is a type of electrical component made up of a single coil, or helix, of wires wrapped around a ferromagnetic center core. This type of inductor is most commonly used to store energy from an alternating current in a capacitor, or for inductive heating or impedance matching in electronic circuits. The LQM21PN1R0NGCD is an example of a fixed inductor that is designed for use in switches, EMI filters, and high-frequency transformer applications.

Design

The LQM21PN1R0NGCD is a surface-mount inductor with an operating frequency range of 100 kHz to 5 GHz. It features an axial leaded suspension with a lead diameter of 0.20 mm, and a variety of sizes ranging from 0.7 mm x 0.3 mm to 4.9 mm x 2.7 mm. This type of inductor also comes in a variety of resistances, from 1k ohm to 100k ohm, so it can be used in a wide variety of electronic projects.

Uses

Fixed inductors are commonly used in a variety of different devices and applications. They are often used as electronic components in switches, for impedance matching in radio frequency circuits, and for EMI filtering. Inductors can also be used to convert electrical energy into magnetic energy, which can then be converted back into electrical energy to power different electrical devices. As mentioned above, the LQM21PN1R0NGCD inductor is especially useful in high-frequency transformer and switching applications.

Working Principle

The LQM21PN1R0NGCD is based on the principle of induction, which states that when a current flows through a conductor, a magnetic field is generated around it, and this magnetic field will induce a current in a nearby conductive material. This induced current is proportional to the change in the amount of current that passed through the conductor. In order for an inductor to provide the desired inductance, a certain number of loops of wire must be wrapped around the core material. The inductance of the inductor is then directly related to the number of loops of wire and the size of the core material.

Conclusion

The LQM21PN1R0NGCD is an example of a fixed, or fixed coil, inductor. This type of inductor is mainly used in electronic switches, EMI filters, and high-frequency transformers. The LQM21PN1R0NGCD is designed with axial leaded suspension and lead diameter of 0.20 mm, and comes in a variety of sizes and resistances. This inductor works based on the principle of induction, in which a current passing through a conductor creates a magnetic field that induces a current in nearby conductive material. Due to its versatile design, the LQM21PN1R0NGCD can be used in a wide variety of projects and applications.
