Abstract
A multilayer LC composite component includes a glass-ceramic composition and internal electrodes containing silver or copper as a main component. The multilayer LC composite component is outstanding in mounting reliability particularly to a resin substrate, easy to manufacture, and has excellent electric characteristics at high frequency. The glass-ceramic composition includes 45 to 35 wt. % of forsterite powder and 55 to 65 wt. % of glass composite powder, and compositions of the glass composite powder include 40 to 50 wt. % of SiO , 30 to 40 wt. % of BaO, 3 to 8 wt. % of Al O , 8 to 12 wt. % of La O , and 3 to 6 wt. % of B O . It is high in flexural strength, moderately high in coefficient of thermal expansion, easy to use in manufacturing a greensheet, and densely sintered at a temperature of less than 950 degrees C.
