Aiming at filter applications, the X7R and X5R MLCC (multilayer-ceramic-capacitor) series provides an alternative to polarized-tantalum and electrolytic capacitors. Packaging for the capacitors ranges from 0402 to 1812 case sizes with 100-pF to 100-μF capacitance values. Prices for the X7R and X5R MLCC series range from 1 cent to $1.
