NASA Space Level BME X7R MLCC
S311-P838 Approved
KYOCERA AVX is the first company to be awarded the NASA S311-P838 specification for its Space BME X7R MLCC
technology. This technology delivers an advanced capacitance voltage capability compared to conventional
PME (Precious Metal Electrode) technologies while meeting the reliability levels demanded by NASA’s space
industry. The technology has several key benefits, downsizing case sizes, reducing weight and allowing more
efficient use of the PCB area available. The range is tested using Mil spec standards and methods including 100%
ultrasonic examination in compliance with the NASA space specification. These surface mount components
also incorporate Flexiterm®, which greatly enhances resistance to any of the mechanical stress experienced by
MLCCs during PCB assembly and in operation.
FEATURES
• Higher CV capability than standard capacitors resulting in reduced size / weight of components and saving in PCB space required.
• Every production lot will have a C of C, DPA and a summary data package.
• Use of Flexiterm® technology for enhanced mechanical stress resistance.
• Case sizes: 0603 - 1812, cap values 2.2nF - 8.2uF available.
• Voltages:16 - 100 Volts
