Product Overview
The CMLW4030S Series is a Wire Wound SMD Power Inductor featuring magnetic-resin shielded construction for ultra-low buzz noise and a metallization on ferrite core for excellent shock resistance and durability. Its 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 space and power. They are ideal for applications including LED lighting, mobile devices, flat-screen TVs, disc recorders, set-top boxes, notebooks, desktop computers, servers, graphic cards, portable gaming devices, personal navigation systems, personal multimedia devices, and automotive and telecomm base station systems.
