Fixed Inductors

A fixed inductor, also known as a fixed coil, is an electronic component which is designed to store electrical energy in the form of a magnetic field, due to the effect of inductance. This phenomenon is based on Faraday’s Law of Induction, where the induced voltage in a coil is proportional to the rate of change of the magnetic field through the area enclosed by the coil. Fixed inductors are commonly referred to as ‘coils’ by electronic engineers, and they are available in a wide range of different forms, sizes and configurations.

LQP02HQ4N0C02E Application Field and Working Principle

The LQP02HQ4N0C02E fixed inductor is commonly used in electronic circuits, where a variable inductance is not required. The component has a four-terminal configuration, consisting of two sets of windings which are magnetically coupled. The two windings are independent, and each is designed to have a specific inductance value. The windings of the LQP02HQ4N0C02E fixed inductor are usually connected in series or in parallel, depending on the application.

The working principle of the LQP02HQ4N0C02E fixed inductor is simple. When a current passes through the component, a circular magnetic field is generated, which induces an opposing current in the second winding. The magnitude of the induced current is proportional to the rate of change of the magnetic field, and the opposing current opposes the flow of the original current, resulting in a decrease in the total current. This decrease in current results in an effective decrease in inductance, as the component acts as a low-pass filter, rejecting high-frequency signals.

The LQP02HQ4N0C02E fixed inductor is often used in applications such as high-frequency circuit design, coupled inductors, filters and voltage regulators. It is also commonly used in DC-DC converters, power supplies and in RF designs.

The component is usually constructed from a ferrite core and copper wire wound around it. The size and shape of the inductor depend upon the requirements of the specific application. In a high-frequency circuit, the inductor should be as small as possible, as it will allow for better frequency response. However, in a low-frequency circuit, the inductor should be larger, as it will have a larger inductance value.

In order to ensure that the inductor is operating as desired, it is important to use a suitable circuit design. This involves the careful selection of components, such as resistors, capacitors and transistors. It is also important to choose the appropriate inductor part number, as different part numbers may be designed for different frequencies and different inductance values.

The LQP02HQ4N0C02E fixed inductor is a reliable and cost-effective electronic component which is widely used in a variety of different circuit designs. It has a simple working principle, and the component is relatively easy to design. The component is available in a wide range of sizes and configurations, making it suitable for a range of different applications.
