Fixed Inductors

Fixed inductors, also known as coils, chokes, or reactors, are passive components that are used to create inductance in an electrical circuit. These components can also be used to filter signals by blocking direct current (DC) while allowing alternating current (AC) to pass through. Fixed inductors are widely used in many types of circuit designs and applications, from power supplies to radio communications, due to their reliable performance.The CF453215-R82K is a type of fixed inductor that is designed to offer high inductance and low power losses in wide frequency ranges. This fixed inductor is mainly used in applications such as power supplies, DC-DC converters, RF amplifiers, mixers, and filters.The working principle of the CF453215-R82K is based on Faraday’s law of induction, which states that an inductor stores energy in its magnetic field due to a change in current. When a current passes through an inductor, it generates a magnetic field around the inductor. This magnetic field induces current and voltage in the inductor, which in turn, creates a force that opposes the current flow. This opposing force is what produces inductance.The CF453215-R82K is composed of an iron or ferrite core surrounded by wire windings that have been wound in layers. The number of wire windings around the core determines the amount of inductance produced. The layers of wire winding act as a magnetic shield to reduce the interference from nearby sources, such as other components or environmental factors. This type of inductor also includes a moulded plastic enclosure that keeps the windings secure and provides necessary insulation for safety.The CF453215-R82K offers excellent performance in a wide range of applications, such as in voltage and current regulation, over voltage protection, power factor correction, RF signal filtering, and for energy storage and transfer. As this type of inductor offers high inductance and low power losses in a wide frequency range, it makes it an ideal component for many circuit designs. It can also be used to reduce spikes and harmonics in a circuit, as the inductor can store and release energy as required.The CF453215-R82K is also designed to have a long service life, due to its robust design and construction. It is able to withstand extreme temperatures, vibration, shocks, and dust and moisture, making it highly reliable in challenging environments. Furthermore, this fixed inductor is lightweight and easy to install and configure, making it suitable for a wide range of applications.As fixed inductors are an essential part of modern circuit designs and applications, the CF453215-R82K offers a reliable and cost-effective solution for many electrical design needs. This type of inductor is designed to provide high inductance and low power losses, ensuring safe, efficient, and reliable performance in many applications.
