AVX Corporation has announced the market introduction of the first space-level, base metal electrode (BME), X7R dielectric MLCCs. Exhibiting capacitance voltage (CV) capabilities superior to those of conventional precious metal electrode (PME) MLCCs, the new BME MLCCs provide higher capacitance values in significantly smaller cases sizes, reducing both board space and total component weight, which are especially critical in space applications, while maintaining the high reliability performance required by the space industry. The new surface mount, BME MLCCs also feature Sn/Pb plating with Flexiterm® terminations, which provide considerably enhanced resistance to mechanical stress by allowing for more than twice as much board flexure as standard terminations.
Qualified on the European Space Association's (ESA's) European Preferred Parts List (EPPL II) under the criteria of the European Space Components Coordination's (ESCCs) specification 3009, AVX's new space-level BME MLCCs are rated for 16-100V and 2.2nF to 8.2µF, are available in case sizes spanning 0603-1812, and, in addition to space applications, are also ideal for use in a range of high-reliability aviation and military applications. Moreover, these devices, included in a line expansion that incorporates case sizes 0402-2220, are also currently being evaluated for approval on the ESCC's Qualified Parts List (QPL) qualification process.
AVX's space-level, BME MLCCs are available in three capacitance tolerances (±5%, ±10%, and ±20%) and with three ESCC lot acceptance testing (LAT) levels. Lead time for the series is 14 weeks and pricing information and datasheets for individual part numbers are available upon request.
