IntroductionFixed inductors are an important element of an electronic circuit, used to store energy in the form of an electromagnetic field. They are capable of converting electrical energy to magnetic energy and back again. The 4494R-826 fixed inductor is a high-performance component used for power supply applications and power factor correction.
ApplicationsThe 4494R-826 fixed inductor is ideal for use in power conditioning applications due to its low profile, high-temperature capabilities, and low-profile construction. It can be used to provide DC-DC conversion from high-voltage sources, such as an automotive alternator, or AC-DC conversion with frequency adjusters. It can also be used for power factor correction in AC mains circuits by providing a low-resistance path for current. This allows the current to be regulated and therefore helps reduce the total harmonics present in the system.
Working PrincipleFixed inductors use Faraday’s Law of Electromagnetic Induction as their working principle. When an electric current passes through a circuit, it generates a magnetic field, which in turn induces an electric field in a nearby conductor. This phenomenon is known as inductance, and is key to the operation of fixed inductors. The 4494R-826 is designed to generate a magnetic field when a current is applied to it, and the strength of this field will depend on the design of the inductor and the amount of current supplied.
StructureThe 4494R-826 fixed inductor is composed of a conventional Ferrite core, formed with a bendable tube-like material. This core is surrounded by wire coils which create a magnetic field when an electric current is applied to the device. The 4494R-826 also includes a control circuit to adjust the current when necessary.
Qualities and AdvantagesThe 4494R-826 fixed inductor is designed for maximum efficiency and low-profile installation. It has excellent mechanical and thermal stability, which allows it to be used in environments exposed to temperature fluctuations, shock, and vibration. Additionally, the 4494R-826 has a flat high-frequency response and has the capability to provide efficient DC-DC conversion. Furthermore, its low-resistance path and low-profile construction make it ideal for applications involving power factor correction.
ConclusionThe 4494R-826 fixed inductor is a high-performance component capable of providing efficient DC-DC conversion and power factor correction. It is ideal for applications where temperature fluctuations, shock, and vibration are present. Its core is formed with a bendable tube-like material, which is surrounded by wire coils to create a magnetic field. Furthermore, its control circuit provides current adjustability when necessary. This fixed inductor has the qualities and advantages of efficient operation, low profile, and high thermal stability.
