Forgive the late response to this message. I believe that there have been
sufficient response regarding the 1210 (sect, 8.2); However, the MELF
problem can be explained in one word "TYPO". The "Z max" dimensions were
repeated in the "X max" column; will be corrected in SM-782 ammendment and
the next revision.
I have pulled up the EM-782 spreadsheets, where the correct dimensions
can be found. The following are the dimensions for Section 8.5 MELF
"X max" with associated RLP NO.:
RLP 200 1.80 mm
RLP 201 2.60 mm
RLP 202 1.60 mm
RLP 203 2.00 mm
RLP 204 1.80 mm
RLP 205 2.60 mm
