Fixed Inductors are commonly used in electrical circuits to enhance the performance of a variety of electrical components. The HPL1005-3N9 is an axial leaded, fixed inductor designed for direct current (DC) applications. It is a 3.5mm wide, 10mm long, 9mm high component constructed from ferrite, an oxidized iron-containing ceramic material with a relative permeability of up to 10.000. The HPL1005-3N9 uses a ferrite core to both increase the inductance and reduce the magnetic flux leakage.
One of the primary applications of the HPL1005-3N9 is as an inductor in DC-DC switching power supplies. Such supplies often employ a transformer, which uses a primary and secondary winding to step up or step down a voltage, and an inductor to deliver the magnetic flux necessary to the transformer\'s ferrite core. Other applications for the HPL1005-3N9 include line filters, differential outputs, noise suppression, and resonant circuits.The working principle of the HPL1005-3N9 is based on Faraday\'s Law of Induction, which states that any change in the magnetic flux through a circuit will induce an electromotive force (EMF) in the circuit. This EMF is proportional to the rate of change in the flux and will cause a current to flow through the coil. The induced current is proportional to the rate of change in flux, and is measured in units of Henrys, named after the scientist Joseph Henry.When the HPL1005-3N9 is subjected to a varying DC current, its ferrite core acts to reduce the rate of change in flux, thereby reducing interference from the current being transmitted. The induced EMF in the coil is also reduced, which results in reduced total losses and improved electrical efficiency in the circuit. The quantity of EMF induced in the inductor is a function of the length of the coil, the current flowing through it, and other parameters such as air temperature and core saturation.The HPL1005-3N9 offers superior electrical performance due to its high inductance, low DC resistance, and low ESR. The ferrite core also helps to provide a higher saturation current without compromising inductance stability. This enables the component to be used in high-efficiency power supplies with low standby power consumption. The component also has a wide operating temperature range, making it suitable for use in both commercial and industrial applications.The HPL1005-3N9 is well-suited for a variety of applications, including power factor correction, active reduction, switching power supplies, and power circuits. In each application, it is used to reduce the EMF induced in a circuit by providing an alternate path for the varying current. This helps to improve the efficiency of the circuit and reduce losses due to interference. By using the HPL1005-3N9, customers can rest assured they are receiving a high-quality inductor that will meet their needs in a reliable and cost effective manner.
