This is a SCBG100505U102T electronic part, which is a Ferrite Beads 0402 RoHS manufactured by Yanchuang. It is primarily used as an electronic component in the design of power supply systems, to attenuate and suppress RF noise. Its ferrite core is a highly efficient noise absorber, providing filtering to reduce high frequency interference. It also features a low profile, high current capacity, and low DC resistance that allows it to easily fit into space-limited applications. It is RoHS compliant, and its 0402 size makes it ideal for high-density applications such as cell phones, medical equipment, embedded systems, and more.
