Fixed inductors, or chokes, are devices typically used in electrical circuits to impede the flow of electric current. The LQM21PN3R3NG0D is a type of fixed inductor with a wide range of applications. This article will explore the particular range of applications of this type of inductor, as well as its working principle.

Application Field

The LQM21PN3R3NG0D inductor is a radial-leaded, through-hole component widely used in consumer electronics. It is a reliable, compact, and low-profile surface-mount inductor with excellent self-resonance, high current capability, and excellent linearity. On the one hand, its low pre-load inductance is ideal for high-frequency switching power supply applications. On the other hand, its high inductance values are suitable for signal line filtering applications.

The LQM21PN3R3NG0D inductor is a popular choice for high-current and high-frequency applications because it offers considerable flexibility and high versatility. Its highly-versatile design can accommodate various frequencies, current ranges, and package sizes. These attributes make the LQM21PN3R3NG0D inductor suitable for a wide range of applications, such as switching power supplies, PWM motor control, RF communication circuits, motor control, and more.

Working Principle

The working principle of the LQM21PN3R3NG0D fixed inductor is based on the concept of inductance. Inductance is the property of a circuit that causes it to oppose changes in current. This resistance to change is created by the magnetic field that is generated by the inductance. In essence, when a voltage is applied to an inductor, the resulting electric field generates a magnetic field that links the inductor and its windings. As current flows through the inductor, the magnetic field creates an induced current in opposition to the applied current.

The inductance of the LQM21PN3R3NG0D inductor is measured in units of henries (H). Thus, higher inductance values will indicate a higher resistance to current changes. At the same time, higher inductance values will also create a greater magnetic field, leading to increased energy storage in the form of an induced current. The LQM21PN3R3NG0D inductor is designed with a high inductance in order to provide maximum performance in applications that require a high level of current control.

In addition to its high inductance, the LQM21PN3R3N3ND also has a high temperature coefficient, which ensures stable performance even in high-power applications. This feature makes it an ideal choice for high-power switching applications, such as motor control circuits and linear voltage regulators.

Conclusion

The LQM21PN3R3NG0D is a type of fixed inductor with a wide range of applications. It has a radial-leaded, through-hole design and offers excellent self-resonance, high current capability, and good linearity. Its high inductance and temperature coefficient make the LQM21PN3R3ND an ideal component for high-power and high-frequency applications, including switching power supplies, PWM motor control, RF communication circuits, motor control, and more.
