AVX puts base-metal electrode X7Rs into space
According to the supplier these capacitors show “capacitance voltage capabilities superior to those of conventional precious metal electrode (PME) MLCCs”.
The BME MLCCs provide higher capacitance values in smaller cases sizes. They also feature Sn/Pb plating with Flexiterm terminations, to increase robustness 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 (ESCC’s) specification 3009, these MLCCs are rated for 16-100V and 2.2nF to 8.2μF.
They are available in case sizes spanning 0603-1812, and case sizes 0402-2220, are also currently being evaluated for approval on the ESCC’s Qualified Parts List (QPL) qualification process.
“BME capacitors further complement our existing line of space capacitors, providing customers with an extended range of trusted, high-reliability solutions for mission-critical applications,” said Michael Conway, Product Marketing Manager at AVX.
The BME MLCCs are available in three capacitance tolerances (±5%, ±10%, and ±20%) and with three ESCC lot acceptance testing (LAT) levels.
