Fixed Inductors: ATFC-0402-2N4B-T Application Field and Working Principle

Fixed inductors are a type of inductor that offers a fixed inductance that does not vary over time or with temperature. The ATFC-0402-2N4B-T is one such inductor that is designed to meet the needs of high frequency applications. This article looks at the application field and working principle of this fixed inductor.The ATFC-0402-2N4B-T is a surface mounted inductor that is used in high-frequency applications such as power converters and RFID receivers. The inductor is constructed using a ceramic-metallic composite material. This material provides low resistance, high inductance, and excellent temperature stability. The inductor is housed in a 0402 package and measures 1.6 mm × 0.8 mm in size.The working principle of the ATFC-0402-2N4B-T fixed inductor is based on Faraday’s law of induction. When a variable current passes through the inductor, it creates a magnetic flux. This flux induces an EMF in the inductor, which opposes the change in the current. The higher the inductance of the inductor, the greater the opposition to the change in the current, resulting in a greater energy storage capacity. The ATFC-0402-2N4B-T fixed inductor offers an inductance of up to 4 nH with a current of up to 0.2 A. The inductor also offers a very low resistance of 0.11 Ω and an impressive current saturation of up to 500 mA. All of these features make the ATFC-0402-2N4B-T an ideal choice for high-frequency applications such as RFID receivers, power line converters, and high frequency switching regulators. The ATFC-0402-2N4B-T also offers excellent temperature stability. The device can operate in temperatures ranging from -40°C to +125°C. This makes it suitable for use in a wide variety of environments, from automotive and medical to consumer and industrial applications.In summary, the ATFC-0402-2N4B-T is a fixed inductor that is designed to meet the needs of high-frequency applications. The inductor offers an inductance of up to 4 nH with a current of up to 0.2 A. It also provides low resistance, current saturation of up to 500 mA, and excellent temperature stability. All of these features make the ATFC-0402-2N4B-T an ideal choice for RFID receivers, power line converters, and high frequency switching regulators.
