FEATURES
DESCRIPTION
MF crystals are ultra-miniature surface-mount mount crystals. Produced with ceramic substrate and hermetically-sealed metal lid the compact size and low mass make this an ideal crystal for high-density applications. Frequency (MHz) Crystal Cut Oscillation Mode ESR (max) (Ohms) OSCILLATION MODE & ESR 12 ~ 16 AT Fund. 80 16.1 ~ 50 AT Fund. 40 40 ~ 67 AT 3rd OT 70 67.0 ~ 100 AT 3rd OT 90 PART NUMBER GENERATION MF crystal part numbers are derived as follows: Example: 16.000MHz MF/ 10/50/10/30pF/ATF Frequency Package - MF Calibration Tolerance at 25°C (in ±ppm) Temperature Stability (in ±ppm) Operating Temperature Range (lower figure of temperature range) Circuit Condition (CL in pF or SERIES) Mode - ATF (AT-Cut, fund.) - AT3 (AT-Cut, 3rd overtone) STOCKHOLDING AND CUSTOM PARTS Certain frequencies and specification of MF crystals are stocked by Euroquartz. Custom frequencies and specifications are readily manufactured to order on short lead times. Contact Euroquartz sales office for details.
