They are not connected to the crystal. The crystal is symmetrical, there is no Pad 1 preference. The part can be rotated 180o when being assembled on the PCB and will still perform correctly. 2 3 Layout and application information • Trace lengths to the crystal should be kept as short as possible. • The crystal connections are sensitive to noise. • The package should be grounded for optimum performance, pad 2 and/or pad 4 connected to ground. Marking • Marking consists of the frequency (may be truncated due to package size) and date code • Date code consists of Month Year (see codes below) • Orientation of marking may be mixed on the tape • Traceability of part is lost once removed from reel Codes for Date Code (Month Year) Code Year Code Month 6 2006 A JAN 7 2007 B FEB 8 2008 C MAR 9 2009 D APR E MAY 0 2010 F JUN 1 2011 G JUL H AUG 2 2012 J SEP K OCT L NOV M DEC www.pletronics.com 425-776-1880 4 SM10T Series Miniature SMD Crystal February 2009 Reflow Cycle (typical for lead free processing) Temperature (°C) 250 200 150 100 175°C±10°C 260°C Maximum 10 Seconds Maximum 215°C±10°C 120 to 160 Seconds Approximately 50 Seconds Allowed rate of temperature change Maximum 4°C per second The part may be reflowed 2 times without degradation.
