Fixed Inductors are electronic components that provide inductive reactance (resistance to the flow of electrical current due to changes in the magnetic field around the inductor). VLS252012ET-3R3M is a three-variable and single-terminal fixed inductor that provides general purpose power management solutions. This inductor is mainly used in applications that require direct current steady-state and low-frequency power management. This fixed inductor also finds use in AC/DC conversion, discrete control circuits, switching power supplies, inverters, rectifiers, and voltage regulation.The VLS252012ET-3R3M inductor features an ultra-performance core material, which provides a significantly higher inductance value at low DC current in comparison to other units. It also features an efficient magnetic coupling that prevents magnetic saturation under higher DC currents for longer periods. The inductor also contains an internal electrode layer that efficiently transports the electrical current throughout the system. The low-profile, surface mount package allows the inductor to be mounted directly on the circuit board.This inductor features extremely low AC impedance, which means that it does not significantly affect the signal path, and can be used in high-frequency models. It also has low DC resistance, which enables the device to work more efficiently. Furthermore, this inductor has low equivalent series resistance (ESR) and equivalent parallel resistance (EPR), thus offering a high degree of stability and reliability in power conversion.The working principle of the VLS252012ET-3R3M fixed inductor is based on Faraday’s Law of Induction. Faraday’s Law states that when a conductor is exposed to a changing magnetic field, then a voltage is induced in the conductor proportional to the rate of change of the magnetic field. This principle is exploited by the VLS252012ET-3R3M fixed inductor.When an AC voltage is supplied to the VLS252012ET-3R3M, a changing magnetic field is generated. This changing magnetic field causes a voltage to be induced across the winding of the inductor. The induced voltage opposes the alternating current, and acts to limit the current flow in the circuit. This phenomenon is known as self-induction, or inductive reactance.The characteristics of the VLS252012ET-3R3M fixed inductor can be adjusted to meet the requirements of the specific application. For example, the inductance can be adjusted to provide a more specific current limit at a given frequency. The VLS252012ET-3R3M inductor is also highly reliable, and its breakdown voltage is significant to reduce the risk of failure.The efficacy of the VLS252012ET-3R3M fixed inductor is dependent on the rated current and the frequency of operation. The inductor should not be operated for extended periods of time at a frequency higher than its recommended rating, as this increases the risk of failure. This device is also sensitive to excessive heat, and the maximum temperature must not exceed its rated temperature limit.The VLS252012ET-3R3M fixed inductor is a useful device in many electrical applications due to its efficient operation and small size. Its wide range of adjustment capabilities allows it to be used in many different circuits and applications. As an example, it is used in AC/DC converters, discrete control circuits, switching power supplies, inverters, rectifiers, and voltage regulation.
