Fixed Inductors

Fixed inductors, also known as inductors or industrial momentum loops, are components used in various electronics and electrical applications. They are passive components and typically consist of a coil of wire wrapped around a core material, which is often made of ferromagnetic material, such as iron alloy or ferrite. They are mainly used to store energy in the form of a magnetic field, as well as maintain currents in different electrical circuits.SPM3012T-4R7M-CA02 is a type of fixed inductor. It is a three-legged surface-mounted component made of ceramic and has a round, cylindrical shape. The product is supplied in an anti-static package for easier use. The body of the inductor is composed of ferrite which is a superior magnetic material with high-quality properties.The SPM3012T-4R7M-CA02 fixed inductor has a wide range of applications, including power supplies, DC-DC converters, switched-mode power supplies, power transformers, radio transmitters, and more. It is suitable for use in both commercial and industrial settings. This type of fixed inductor is excellent for filtering or smoothing application in the power supply systems. With its small size and low profile, this inductor is also perfect for space-constrained applications.The working principle of SPM3012T-4R7M-CA02 fixed inductor is based on Faraday\'s law of electromagnetic induction, which states that a changing magnetic field generates an electromotive force (EMF) in a conductor. When an alternating current (AC) runs through the inductor\'s coil, the magnetic field around it is continuously changing. This creates a base EMF which induces an electric current in the coil. The current in the coil, in turn, produces its own electromagnetic field which interacts with the field generated by the passing electric current, creating a voltage drop known as back EMF. This back-EMF in effect slows down the current in the coil, allowing the inductor to store and release energy in the form of a magnetic field.Overall, SPM3012T-4R7M-CA02 fixed inductor is an important passive component used in many electronic and electrical applications. It is small, low profile, and highly efficient, which makes it suitable for use in a variety of industrial and commercial settings. Its working principle is based on Faraday\'s law of electromagnetic induction and it offers excellent filtering or smoothing capabilities in the power supply systems.
