Fixed inductors are components used in electronic circuits that are manufactured using various methods and materials. The ATFC-0402HQ-4N7B-T inductor is a surface mount fixed inductor with a small profile and a wide variety of application fields. The ATFC-0402HQ-4N7B-T uses a ferrite core and utilizes surface mount technology to adhere the inductor to the printed circuit board.

The ATFC-0402HQ-4N7B-T has an inductance value of 4.7 nanohenries (nH), an initial tolerance of +/- 10% and an inductor self-resonant frequency of 1.2 GHz. Its dimensions are 0402 inches (1.0 x 2.0 mm), making it suitable for usage in tight, confined spaces. The inductor\'s resistance values range from 0.14-0.56 ohms, its current rating ranges from 220-445mA, and its works dissipation is 1.8 W.

The ATFC-0402HQ-4N7B-T inductor is used in various application fields such as personal computers, network infrastructure, cell phones, base stations, imaging devices, and automotive electronics. It is also used in power equipment such as power filters, Hertzian chains, switching power supplies, and converters.

The working principle of the ATFC-0402HQ-4N7B-T inductor is simple and straightforward. The inductor, in the most basic terms, opposes changes in current. When there is a voltage applied to the inductor, a current will flow through it, generating a magnetic field. This magnetic field induces an electromotive force (EMF) in the inductor. The EMF, in turn, opposes the applied voltage, creating a counter emf, which redistributes the voltage across the inductor. As the current decreases, the magnetic field collapses, resulting in a self-induced EMF that works against the decrease in current.

As a result, the inductor stores energy and releases it when needed. This can be seen in applications such as power supplies, where the inductor aids in supplying current to the load and in smoothing out any spikes or shifts in the applied voltage. In addition, the inductor is used in AC circuits to filter out any noise or interference.

The ATFC-0402HQ-4N7B-T inductor is a great asset to the electronics field, as it is compact in size while still offering a wide range of applications and useful features. Its ability to store and release energy makes it a great choice for many applications, and its suitability for tight spaces is useful in devices such as personal computers and handheld electronics. Overall, the ATFC-0402HQ-4N7B-T is a great addition to the fixed inductor family.
