Insulating ceramic composition and ceramic inductor using the same

摘要

An insulating ceramic composition which comprises 62-75 wt% of silicon oxide (in terms of SiO2), 4-22 wt% of barium oxide (in terms of BaCO3), 0.5-2.5 wt% of aluminum oxide (in terms Al2O3), 0-0.8 wt% of chromium oxide (in terms of Cr2O3), 0.2-0.8 wt% of calcium oxide (in terms of CaCO3), 8-18 wt% of boron oxide (in terms of B2O3), and 0-2.5 wt% of potassium oxide (in terms of K2O). A ceramic inductor made of said insulating ceramic composition.
