AVX Corp.’s M123 Series MIL-qualified ceramic capacitors are designed for

high performance applications in BX and BR voltage levels, and for

temperature stable applications in BP and BG voltage levels. The M123A10-

M123A23 have been tested in accordance with MIL-PRF-123 specifications

and are available in a wide range of values and tolerances.

M123 Series capacitors offer design and component engineers a proven

technology for SMD processing and applications requiring space-level reliability.

They are designed for use in critical frequency applications, timing circuits, and

applications where absolute stability is required (BP and BG), as well as in

applications where a wider capacitance variation in temperature, voltage,

frequency, and life span can be tolerated (BX and BR).
