Fixed Inductors

Fixed inductors are widely used in electronic circuits. AIMC-0402-R12J-T is a type of fixed inductor designed for use in mobile phone or portable communications applications. It is a robust, low-profile, high-efficiency device with a small footprint that simplifies production and maintenance. This article will discuss the application field and working principle of AIMC-0402-R12J-T fixed inductor.AIMC-0402-R12J-T is a type of common mode EMI filter inductor that mainly used in notebook computers, smartphones, tablets and other portable electronic devices. It features a miniature size of 0402, high current saturation of 1.2 mA, low DCR of 12 mΩ, and a flat-top winding shape suitable for many miniaturized applications. It is mainly used in AC-DC noise reduction, PAM switching circuit, and low-noise power supply system applications for a wide range of electronic products.AIMC-0402-R12J-T fixed inductor works based on Inductors principle. An inductor is an energy storage component consisting of a coil of conductive wire, an iron core, and a ferrite core. When current passes through the coil, it produces an electromagnetic field that stores electrical energy. This stored energy can be released when the current decreases, and the inductor works by this principle.AIMC-0402-R12J-T applies this principle by using the coil windings to store the electrical energy. When current flows through the winding, it produces a magnetic field, which stores the energy that is then released when the current decreases. The electrical resistance of the coil absorbs some of the energy, which is why the device has a low DCR. The ferrite core helps to further reduce the DCR, allowing the energy to be stored more efficiently.The flat-top winding shape of AIMC-0402-R12J-T fixed inductor provides a low profile that is great for miniaturized applications. The flat-top shape also helps with thermal dissipation, which is important in such a small size. Furthermore, the high current saturation ensures that the device can handle large current spikes in demanding applications. In addition, the AIMC-0402-R12J-T fixed inductor features excellent EMI shielding performance. The magnetic field produced by the coil helps to shield the device from electromagnetic interference from other components. Furthermore, the ferrite core helps further reduce the propagation of electrical noise.In summary, the AIMC-0402-R12J-T fixed inductor is suitable for mobile phone or portable communications applications, providing an excellent solution for EMI filtering, low noise power supply systems, and PAM switching circuits. It features a low profile, high current saturation, and low DCR, making it ideal for miniaturized applications. Its flat-top winding shape and ferrite core help to provide excellent EMI shielding performance, ensuring reliable performance in even the most demanding applications.
