NOTES: a. All linear dimensions are in millimeters and parenthetically in inches.
b. Centerlines of character segments and decimal points are shown as dashed lines. Associated dimensions are nominal.
c. The true-position pin spacing is 2.54mm (0.10”) between centerlines. Each centerline is located within 0.26mm (0.010”) of it’s true longitudinal
position relative to pins 4 and 11.
