Unknowns stay unknown.

  • The 10.29 mm source value is mated height, not isolated header body height or a general Micro-Fit envelope.
  • No pin numbering, equipment functions, solder-land reconstruction, current derating or mating assembly approval is provided.
  • No numbered electrical contact assignment, hardware test, specimen measurement, fabrication approval or complete application rating/derating is established.
