Fixed inductors refer to inductors whose inductance values remain substantially constant over a wide range of applied signal frequencies. ATFC-0402-1N9B-T, as one of them, is a small-sized and surface-mountable inductor, with a high inductance value of 2.2uH, a high current rating of 160mA and a low DC resistance of 0.6Ω. This makes the ATFC-0402-1N9B-T a perfect choice for DC-DC power supply circuits, providing superior power efficiency in space-constrained applications.

The ATFC-0402-1N9B-T is widely applied in mobile phones, neonatal monitors and laptop computers. In mobile phones, ATFC-0402-1N9B-T is used extensively in the switching power supply to reduce noise and boost energy efficiency, reduce electromagnetic interference (EMI) and ensure long-lasting operation. In neonatal monitors, by utilizing the low DC resistance of the ATFC-0402-1N9B-T, together with its high inductance value, high current rating, and small size, it can effectively reduce device power consumption and yield a longer battery life; while in laptop computers, ATFC-0402-1N9B-T acts as a high-performance EMI and RFI filter that helps to limit the amount of interference and create a more enjoyable user experience.

The ATFC-0402-1N9B-T works by storing energy in the form of a magnetic field as it is energized by an AC or DC current. During the positive half cycle of the current, the magnetic field is built up, and stored by the inductor. During the negative half cycle of the current, the magnetic field is released and dissipates, inducing a current in the opposite direction. By managing and maintaining this cyclic flow of current, the device is able to regulate and conserve energy, which increases efficiency and reduces power losses.

In conclusion, the ATFC-0402-1N9B-T is an invaluable addition to any fixed inductor-based circuit. Its small size, high inductance value, high current rating and low DC resistance make it an excellent choice for space-limited applications such as mobile phones, neonatal monitors, and laptop computers.
