Background

Low profile trend of chip power inductor resulted from slim trend of mobile phone and mobile equip-ments Improve failure rate due to low body strength of winding type power inductor Low cost replacement for winding type power inductor

Item	Winding Type Chip Power Inductor	Multilayer Chip Power Inductor	Advantages
Body Strength	- High failure rate owing to low body strength - Low mounting speed	- Low mounting speed - Sufficient body strength to SMT - High mounting speed (about 3 times faster than winding type)	- Low failure rate - Cost saving for quality management
Size	- Possible up to 2.5×2.5×1.0(㎣) - Hard to assemble due to very low body strength of low profile	Possible up to 2.0×1.6×0.8(㎣) or 3.2×1.6×0.6(㎣)	- Slim (Low profile) - Miniaturization
