AVX Corp. recently announced that, after several years of extensive testing, its space-level X7R base metal electrode (BME) MLCCs have achieved the European Space Association's (ESA's) Qualified Parts List (QPL) status under the criteria of the European Space Components Coordination's (ESCC's) 3009/041 specification.
Exhibiting capacitance voltage (CV) capabilities superior to those of traditional precious metal electrode (PME) MLCCs, space-level BME MLCCs provide the high reliability performance required by the space industry while delivering high capacitance values in small cases sizes, enabling reductions of board space, weight, and component count, which directly translate into launch cost savings.
Featuring Sn/Pb plated Flexiterm terminations, AVX's space-level X7R BME MLCCs also provide enhanced resistance to mechanical stress by allowing for more board flexure than standard terminations, especially in large case sizes. Currently available in 0603 1812 sizes (with 0402 and 2220 parts in the midst of QPL evaluation), the series is rated for 16 100V and 2.2nF to 8.2µF, and is ideal for I/O filtering and bulk storage in the switch mode power supplies (SMPS) in space and satellite communications, military defense and weapons, and radar systems.
AVX's space-level X7R BME MLCCs are currently 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 is available upon request.
