NASA SPACE LEVEL BME X7R MLCC
S311-P838 Approved
AVX is the first company to be awarded the NASA S311-P838 specification for
its Space BME 7XR 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
