Fixed Inductors are components used in electrical and electronic circuits to produce inductance. The ATFC-0402-2N0B-T, which belongs to this category, is a miniature surface mount inductor. The ATFC-0402-2N0B-T has a 2nH rating, which is the design parameter denoting inductance. It has also been rated to carry a maximum DC current of (400mA). This component is manufactured in a 0402 package size, which is a miniature packaging style suitable for automated assembly using soldering robots. In terms of application field, the ATFC-0402-2N0B-T has wide usage in power supply units and other DC circuits. It is commonly used in switching power supplies, cable modems, mobile phones, smartphones, and other lightweight, small-sized electronic devices. The working principle of the ATFC-0402-2N0B-T is based on the process of converting electrical energy into magnetic energy. An electrical current flowing through a wire creates a magnetic field around it. This magnetic field interacts with that of an inductor. A basic inductor consists of a wire wound around a core material such as iron, magentic steel, ferrite, and powder cores, etc. When the electrical current passes through the inductor, electricity magnifies the magnetic flux around it. This signifies that inductors oppose the flow of current and thus cause a buildup in the electrical voltage. The rate of buildup is affected by the inductance, which is a measurement of the opposition of current caused by the inductor in an electrical circuit. Commercially available inductors often employ a combination of winding-to-core ratio and core material to produce the desired inductance. In the case of ATFC-0402-2N0B-T, the core material is a ferrite, which exhibits low magnetic losses and is ideal for producing high-frequency inductors. The winding-to-core ratio of this model of inductor has been carefully crafted to offer a relatively higher amount of inductance while delivering good DC current support. For reliable performance, ATFC-0402-2N0B-T inductors come with a high saturation current and good temperature stability. This ensures that the operating temperature of the inductor remains within specified limits, and that any voltage or current increases caused by changes in temperature or other factors are kept very low. For automated assembly, ATFC-0402-2N0B-T inductors can be implemented using a combination of solder paste and pick-and-place machine. The core of the inductor is first embedded in the solder paste and then placed in the desired location on the board. The application of heat causes the solder paste to melt and bond the inductor securely on the board. This ensures that the inductor remains firmly in its place and is protected from any shocks or compressive forces. Summarising, the ATFC-0402-2N0B-T is a miniature surface-mount inductor with a 2nH inductance rating and a maximum DC current rating (400mA). It is designed for automated assembly and finds application in switching power supplies, cable modems, mobile phones, and other small-sized electronic devices. The working principle of this inductor is based on the process of converting electrical energy into magnetic energy, with the core being a ferrite material and the winding-to-core ratio offering a higher amount of inductance with good DC current support.
