Fixed Inductors Overview

Fixed inductors, also known as chokes or coils, are a type of electrical component that stores energy in the form of a magnetic field and is used to block, filter, or stabilize current. Fixed inductors are widely used on a variety of circuits, from signal filters to power supplies, for a variety of reasons, and can be found in almost all electrical and electronic devices. The most common type of inductor is the wire coil, but other types are available, such as multilayer ceramic chip inductors, or MLCI, and ferrite bead inductors.

LQP03TNR12H02D Inductor Application Field and Working Principle

The LQP03TNR12H02D is a general-purpose fixed inductor manufactured and marketed by Murata Electronics, which performs well in power supply circuits. Its rated inductance is 3.3 μH and the rated current is 1.2A. It is a molded type inductor commonly used in dc/dc converters, voltage limiters, emi filters, switches, and other applications.The LQP03TNR12H02D utilizes four core parts for its construction: the coil, the ferrite core, the shield, and the insulation material. The coil is made of enameled copper wire, while the core is usually made of ferrite in order to support higher inductance. The shield acts as an electrostatic capacitor to protect the coil and core from undesirable electromagnetic interference (EMI). Lastly, the insulation material helps to provide the entire component with good moisture and thermal resistance.The working principle of the LQP03TNR12H02D inductor is relatively straightforward. When an alternating current runs through the coil of the inductor, an electromagnetic field is generated. This magnetic field then interacts with the core, which results in inductance. The amount of inductance produced is dependent on the number of turns in the coil, the size of the core, and other factors, such as temperature and frequency.The LQP03TNR12H02D can be used in various circuits, but is most commonly employed in isolated dc/dc converters, audio filters, voltage limiters, emi filters, and other similar applications. It is widely known for its excellent performance, high quality, and reliable results.

Conclusion

The LQP03TNR12H02D fixed inductor is a highly versatile component that can be used in a wide variety of applications. With its high quality construction and excellent performance, it is a great solution for a variety of needs. Its features and applications make it an ideal choice for any electronics project, and its reliability allows for the completion of projects with confidence.
