MLCCs Combine High Volumetric Capacitance with Low ESR
Wed, 01/14/2009 - 9:43am
Novacap introduces its line of high-capacitance multilayer ceramic capacitors (MLCCs) that combine high volumetric capacitance per given board area with low equivalent series resistance (ESR). The high-capacitance devices in the X7R and X5R series are packaged in 0402 to 1812 case sizes with a capacitance value range from100 pF to 100 µF. These devices are suitable for replacing polarized tantalum and electrolytic capacitors to simplify manufacturing. Their low ESR characteristics allow for comparable filter circuit designs to be achieved at typically one-third to one-fifth of the capacitance values. Additionally, these devices offer improved reliability performance over tantalum and electrolytic capacitors, utilizing less power. Applications include digital circuits, power supply bypass capacitors, LCD modules, smoothing capacitors and input-output filters in DC/DC converters.
