Abstract:
A dielectric ceramic composition including a first component and a second component. The first component comprises an oxide of Ca of 0.00 mol % to 35.85 mol % an oxide of Sr of 0.00 mol % to 47.12 mol %, an oxide of Ba of 0.00 mol % to 51.22 mol %, an oxide of Ti of 0.00 mol % to 17.36 mol %, an oxide of Zr of 0.00 mol % to 17.36 mol %, an oxide of Sn of 0.00 mol % to 2.60 mol %, an oxide of Nb of 0.00 mol % to 35.32 mol %, an oxide of Ta of 0.00 mol % to 35.32 mol %, and an oxide of V of 0.00 mol % to 2.65 mol %. The second component includes (by mass) at least (a) an oxide of Mn of 0.005% to 3.500% and (b) one or both of an oxide of Cu of 0.080% to 20.000% and an oxide of Ru of 0.300% to 45.000%.
