Fixed inductors are passive components that consist of a coil of wires wound around a core, generally made of ferrite, ceramic, or air. Fixed inductors provide electromagnetic energy storage, which provides a specific inductance that is necessary for many electrical circuits. The IHB3BV471K is a type of fixed inductor, which has specific benefits and applications.The IHB3BV471K is studied for its applications in DC-DC converters, EEPROMs, and ESD circuits, making them ideal for use as inductors in power factor korectors (PFCs). The inductance of the IHB3BV471K also makes it ideal for usage in battery chargers and motor driver circuits.The working principle of the IHB3BV471K is the same as that of any other fixed inductor. Essentially, when an alternating current is generated through the winding of the inductor core, magnetic flux is created. This flux then reacts with the inductor, producing an electromagnetic field. The strength of this electromagnetic field is based on the size of the core, the amount of current going through it, and the applied frequency.In the case of the IHB3BV471K, the inductance of the electromagnetic field is approximately 80. 8 μH, which is well above the typical values of 0. 05 – 0. 5 μH, making this inductor suitable for DC-DC conversions and ESD circuits.The windings of the IHB3BV471K are formed into a “hairpin” shape, and this unique design helps to reduce magnetic interference. This hairpin shape also helps to reduce the core losses caused by eddy current. This design helps the IHB3BV471K resist the high temperatures and direct current surges it may encounter in power factor korectors (PFCs).The body of the IHB3BV471K is made from high temperature resistant plastic, which helps it to dissipate heat more efficiently. This also helps to reduce the losses caused by damaging current surges. Overall, the IHB3BV471K is a powerful and reliable fixed inductor, which is useful for many applications. When used as an inductor in DC-DC converters, EEPROMs, or ESD circuits, the IHB3BV471K can provide strong magnetic fields with excellent reliability. The unique hairpin shape of the IHB3BV471K also helps it to resist high temperatures and direct current surges, making it ideal for PFCs.
