Reportedly, the X7R and X5R series high-capacitance multilayer ceramic capacitors (MLCCs) from Novacap combine higher volumetric capacitance per given board area with lower equivalent series resistance (ESR) than comparable components. They are available in 0402 to 1812 case sizes with a capacitance range from 100 pF to 100 µF. Additionally, the capacitors promise improved reliability performance over tantalum and electrolytic capacitors while consuming less power. Typical applications include digital circuits, power-supply bypass capacitors, LCD modules, smoothing capacitors, and input-output filters in dc-dc converters. Prices range from $0.01 to $1 each.
