Fixed Inductors: ATFC-0402-2N7B-T Application Field and Working Principle

Fixed inductors are electrical components used in circuit boards to regulate the flow of electrical current. Specifically, the ATFC-0402-2N7B-T is a small, surface-mount fixed inductor with a tolerance of 10 %. It is often used for circuit board applications in automotive, telecom, and industrial electronics.Fixed inductors are also known as chokes or coils and are usually made up of a coil of wire, or a coil of wire wound around a ferromagnetic core. When electricity flows through the inductor, the magnetic flux created by the current causes a magnetic field to be formed around the inductor. The magnetic field will oppose the flow of electric current. This resistance to the electric current prevents any sudden spikes or fluctuations in the current, giving it the characteristic of a smooth, regulated flow.Fixed inductors are usually rated by two numbers: the inductance and the current-saturation capability. The inductance is the amount of resistance to the flow of electric current produced by the magnetic field. The current-saturation is the maximum electric current an inductor can withstand without damage; this is often expressed as a maximum peak current. The ATFC-0402-2N7B-T has a rated inductance of 2.7 uH and a saturation current capability of 370 mA.The ATFC-0402-2N7B-T is particularly well-suited for applications that require a low-profile surface-mount inductor. This device is just 0402 mm in size, making it suitable for space-constrained situations. Additionally, it has a high self-resonance frequency of 2.8 GHz, making it suitable for many radio frequency applications.The ATFC-0402-2N7B-T\'s design also makes it suitable for a variety of high-temperature applications. It is rated to operate at temperatures up to 105°C, making it ideal for use in automotive, telecom, and industrial electronics.Due to its size and heat tolerance, the ATFC-0402-2N7B-T is often used in automotive systems such as anti-lock braking systems, airbag deployment systems, and navigation systems. These applications all rely on high-speed, reliable electrical signals that are free of sudden spikes and fluctuations in current. The ATFC-0402-2N7B-T\'s fixed inductor ensures that only a steady, regulated current is produced, making it an ideal choice for these applications.In telecom applications, the ATFC-0402-2N7B-T is often used as an impedance-matching device. It is used to regulate and adjust the current before it is sent to a signal processor. This ensures that the current is uniform and free of electrical noise that could affect the signal accuracy.In industrial electronics, the ATFC-0402-2N7B-T is primarily used as an energy-storage device. It absorbs and stores energy in a magnetic field that can then be used to power other electronic components.The ATFC-0402-2N7B-T is an extremely versatile, reliable component that can be used in a wide variety of applications. Its surface-mount design makes it well-suited for space-constrained applications, while its high-temperature tolerance and self-resonance frequency make it suitable for many high-speed applications. Its ability to regulate and adjust current ensures that it can be used in automotive, telecom, and industrial applications, making the ATFC-0402-2N7B-T a valuable component for many circuit board designers.
