Thru-Hole Power Inductor  
E L E C T R O N I C S I N C .  
EPIXXXXXXAC5 & EPIXXXXXXAC5-LF  
• Optimized for National’s LM257X Series  
• Low loss material ensures operation in high frequency switching  
converters, such as Buck, Boost or as output averaging filter inductor  
• Also suitable for use in high quality filter applications  
• Add “-LF” after part number for Lead-Free  
• 52 KHz Switching Frequency  
• Low Cost Inductor
