Product Overview
The CMLW4012S Series is a wire wound SMD power inductor featuring magnetic-resin shielded construction for ultra-low buzz noise. Its metallization on the ferrite core provides excellent shock resistance and durability, while the closed magnetic circuit design minimizes leakage flux and EMI. These inductors offer a 30% higher current rating than conventional inductors of equal size, saving PCB real estate and power. They are ideal for applications such as LED lighting, mobile devices, flat-screen TVs, disc recorders, set-top boxes, computers, servers, graphic cards, portable gaming devices, personal navigation and multimedia devices, and automotive and telecommunication systems.
