Fixed inductors refer to components that store energy in an electric field in the form of a coil. Generally, they are made of copper wire, enameled wire and ferrite core. The structure of a typical fixed inductor usually includes a winding, a core and a lead. Inductors are generally categorized into two type: ferrite core and air core. They are mainly used to store energy and to create impedance in a DC or AC circuit. The most common type of fixed inductors is the LQP02HQ0N6C02E type. This article will provide an overview of the field of application and working principle of this inductor.

Application field

The LQP02HQ0N6C02E type inductors are widely used in communication systems, such as cell phones, wireless systems, radio broadcasting and other fields. They are also used in Power Electronics, which mainly deal with voltage, energy and current. They are also used in LCD TV and in other complex digital systems. In general, they are often used in power application such as: switching regulators, flyback and forward converters, audio applications, telecommunication systems, balanced modulators, and band-pass filters.

Working principle

Inductors are two-terminal electrical passive components that can store energy in the form of a magnetic field. When a voltage is applied across the two terminals, the magnetic field induces current through the conductor winding, which produces a reaction voltage across the terminals. The amount of current induced is proportional to the applied voltage and frequency, and also is dependent on the quantity of windings and size of the core material.

The core material and the number of windings are essential factors when constructing an inductor. In general, an often-used core material is ferrite, due to its excellent magnetic properties, its low cost and its high Q Factors (higher capacity for storing energy). A typical ferrite material exhibits high inductance values in 1-10MHz range while an air core offers an inductance of high frequency (above 50MHz). Since an air core uses no ferrite material, they also have higher permeability and better control of Q Factor and inductance.

The inductance of the LQP02HQ0N6C02E type inductors varies from one to another; while one model might have an inductance of 27μH, another could have an inductance of 30μH. As a result, their large footprint and low-profile design make them an ideal choice for controlling power in today’s increasingly compact devices.

The working principle of the LQP02HQ0N6C02E type inductors is simple. They create a magnetic field when a current is passed through the winding. This magnetic field induces a voltage across the two terminals, which is proportional to the amount of current passing through the winding. This voltage can then be used to create impedance in a DC or AC circuit.

Conclusion

The LQP02HQ0N6C02E type inductors are a type of fixed inductors which are widely used in communication systems, Power Electronics, LCD TVs and other digital systems. They are also used to store energy and to create impedance in various circuits. This article has provided an overview of their application field and working principle.
