Compact power inductors for highly-efficient DC-DC switching controllers

24-06-2016 | Wurth | Passives

W├╝rth Elektronik has expanded its portfolio of compact SMD power inductors with two new series - the WE-PMMI and WE-PMCI. The two new power inductors are used, for example, in highly-efficient DC-DC switching controllers with a low space requirement. The WE-PMMI (Power Moulded Multilayer Inductor) series is manufactured in the multilayer process. The RDC value is significantly reduced by pressing a double silver layer. Besides a high current loading capacity, the series available in 0806, 0805 LP and 0806 LP packages also has high saturation current values and, as a result of its low RDC, is suitable for efficient switching controllers with switching frequencies up to 20MHz. The WE-PMCI (Power Moulded Chip Inductor) is a compact pressed power inductor with wire winding, available in five package sizes and three types. The product series excels through its excellent 'soft saturation behaviour' and is also suitable for portable applications with switching frequencies up to more than 20MHz.
