Additional Details

The XFL4020-222MEB has an inductance value of 2.2 µH (222 = 22 x 10^1 nH = 2.2 uH). The DC resistance (DCR) is typically very low, contributing to high efficiency. The saturation current is the current at which the inductance drops by a specified percentage (typically 20%). The shielded construction helps to contain the magnetic field within the inductor, reducing EMI. The inductor is designed for surface-mount technology (SMT) assembly. The compact size allows for high-density placement on PCBs. The XFL4020 series inductors are available in various inductance values to meet different circuit requirements. The materials and construction are designed for high reliability and long-term stable performance. Proper selection of the inductor value is crucial for optimizing the performance of DC-DC converters.
