Surface Mount Power Inductor
ELECTRONICS INC.
EPI KSP56 & EPI KSP56-LF Series
• Low loss material ensures operation in high frequency
switching converters, such as Buck, Boost or as output
averaging filter inductor, coupled inductor or flyback transformer
• Low cost Robust construction to withstand most SMT processes
• Also suitable for use in high quality filter applications
• Add “-LF” after part number for Lead-Free
• Very low core loss ferrite materials
