www.DataSheet.co.kr XT38T Vishay Dale Tuning Fork Crystal FEATURES Miniature package Low cost kHz frequency Tight tolerance The tuning fork type quartz crystal provides ultimate in size, performance and economic trade-offs. So it is used as a clock source in communication equipment, measuring instrument, microprocessor and other time management applications. 100 % Lead (Pb)-free and RoHS compliant RoHS COMPLIANT STANDARD ELECTRICAL SPECIFICATIONS PARAMETER Frequency Range Frequency Tolerance Frequency Coefficient Operating Temperature Range Storing Temperature Range Shunt Capacitance Motional Capacitance Load Capacitance Insulation Resistance Drive Level Aging (first year) Equivalent Series Resistance(ESR) SYMBOL FO ΔF/FO K TOPR TSTG CO C1 CL IR DL Fa Rs CONDITION at 25 °C ref to 25 °C UNIT kHz ppm ppm/(Δ°C)2 °C °C pF fF pF MΩ µW ppm KΩ MIN TYPICAL 32.768 ± 20 - 10 - 20 1 500 - 5.0 1 + 5.0 35 0.85 2 12.5 - 0.042 + 60 + 70 2 4 MAX 100 VDC at 25 °C ± 3 °C DIMENSIONS in inches [millimeters] PARABOLIC TEMPERATURE CURVE TEMPERATURE (° C) - 20 - 10 0 10 20 30 40 50 60 70 0.326 [8.28] Max 0.122 [3.1] Max 0.012 [0.30] - 10 - 20 0.354 [9.0] Min 0.043 [1.1] - 30 - 40 - 50 ORDERING INFORMATION XT38T MODEL 32.768 kHz FREQUENCY/kHz e2 JEDEC LEAD (Pb)-FREE STANDARD - 60 ∆ F/f (ppm) To determine frequency stability, use parabolic curvature (k). For example: What is stability at 45 °C? 1) Change in Temperature (°C) = 45 - 25 = 20 °C 2) Change in Frequency = - 0.0...
