2004 kemet Electronics Corp. E-mail: Page 1 of 6 Technical Update Comparison of Ceramic and Tantalum Capacitorsi BASIC DIFFERENCES Ceramic capacitors have a multitude of dielectric types available and each of these types is characterized by their sensitivities to temperature, but not to voltage or time. This paper compares the X7R, X6S, or X5R dielectric types of ce-ramic capacitors with Tantalum capacitors . Ceramic capaci-tors constructed with these dielectrics offer moderate dielec-tric constants with moderate temperature and voltage sensi-tivities. They overlap with Tantalum capacitors in capaci-tance/voltage range offerings. In many cases, the solder pad geometry allows swapping of Ceramic 0603, 0805, 1206 or 1210 chip sizes with J, R, A, or B case tantalums, re-spectively.
