Range Storage Temp. Range Description The 32S12 Series is a micro-miniature, plastic-molded, surface mountable version of the 32.768 kHz tuning fork-type quartz crystal. The crystal is housed in a rugged, high-temperature tubular holder, then mounted to a leadframe and injection molded into its plastic carrier. Two sizes and two lead connection configurations are available. Applications & Features • Very small, compact packaging • Rugged, plastic-molded design, resistant to shock and vibration • Excellent resistance to heat shock and environmental characteristics • Ideally suited for automated pick-andplace assembly environments • Available on tape and reel • Ideal for portable applications, time of day clocks, communication equipment, pagers, cellular telephones, camcorders, and micro computers Environmental / Process Specifications High Temperature Storage: Low Temperature Storage: Thermal Shock: Shock: Resistance to Soldering Heat: Solderability: Terminal Strength: Less than ±5 ppm change after 500H at 80°C Less than ±5 ppm change after 500H at -30°C Less than ±5 ppm change at 25°C after -25 to +80°C 20 cycles each 1 H MIL-STD-883, Method 2002, Condition B MIL-STD-202, Method 210, Condition I or J Maximum of two (2) reflow passes MIL-STD-883, Method 2003 Will withstand pull weight of 500 grams, 30 seconds maximum Part Numbering Guide 32 S 12 Frequency 32.768 kHz C (T) Package Option Blank = Bulk packed (T) = Tape / Reel* *full reel increments only SaRonix Package Type & Lead Connection A, B, C ( see package configurations) Load Capacitance 12 = 12.5 pF (standard load capacitance) Example PN: 32S12B DS-107 REV E www.pericom.com Tuning Fork Quartz Crystals Technical Data Package Details ������� ���� �� � ���� ���� ��� ��� ���� ��� � � � ���� ����� � � � ���� ��� � � � ���� ��� ��� ���� ���� ��� �������� ���������� ���� ���� ���� ���� ��� ���� 32.768 kHz Plastic SMD 32S12 Series Frequency vs. Temperature Characteristics � ��� ��� � � � � � ��� ��� �� ��� ��� ��� ��� ��� ��� � �� �� �� �� �� �� �� �� ����������� � �� ������ ������� ���� ���� ��� ���� ���� ���� Solder Reflow Guide ��� ����������� � �� ������ ����� ��� � � � � � �� ��� ��� ������� ���� � ���� ��� ���� ��� ��� ���� ��� ��� ���� ��� ���� ������� ��������� ��� ���� ��� � � � ���� ������� ��� ����� ������� ��� ��� � � �� ��� ���� � � � ������� � ��� ��� �� ��� ��� ������ ������� ��� ���� ��� ���� ��� ���� ���������� ���� ����� ������ ���� � ���������� �� �� � ������ ���� ���� ���� ���� ��� ���� Lead Configurations �� �� �� �� �� �� ������ �� �� �� �� ������� ������ ������ �� �� ������ ������ � ��� �� ������� ������������� **Note: for package A and C options, pins #2 and #3 provide mechanical support only.
