WE-PMCI and WE-PMMI Power Inductors

Wurth Electronics offers its power multilayer metal alloy inductor and power molded chip inductor

Image of Wurth Electronics' WE-PMCI and WE-PMMI Power InductorsWurth Electronics' WE-PMCI are compact molded power inductors with wire winding. These product series is characterized by its soft saturation current and is appropriate for small, portable applications with switching frequencies over 20 MHz. These are available in sizes 0603 LP, 0805, 0806, 0806 LP, 1008, 1008 HS, 1210, and 1210 HS.

Wurth's compact power inductor WE-PMMI series are produced using multilayer thick-film technology. The series features high saturation current and high rated current. These devices are suitable for high efficiency switching regulator with switching frequencies up to 20 MHz. These are available in sizes 0806, 0805 LP, and 0806 LP.
