SM7 Ceramic Surface Mount Crystal The SM7 series incorporates a sub-miniature AT-cut strip crystal resonator housed in a miniature 5.0x3.2x0.9mm ceramic package. These compact crystals are ideal for surface mount, densely-populated PCB applications. • Rugged AT-cut crystal construction • Ultra miniature for maximum spacing saving • Ideally suited for disc driver, PCMCIA, PC’S and hand-held products • Tight specifications available • Complies with Directive 2002/95/EC (RoHS Compliant) Specifications: SM7 Frequency Range: 12 MHz ~ 45 MHz Fundamental 36 MHz ~ 121 MHz Overtone Operating Temperature: 0 °C ~ +50°C -A -10 °C ~ +60°C -B -20 °C ~ +70°C -C -40 °C ~ +85°C -L Storage Temperature: -55 °C ~ +125°C Frequency Tolerance: ± 50 ppm -50 (at 25 °C) ± 30 ppm -30 ± 20 ppm -20 ± 10 ppm -10 Frequency Stability: ± 50 ppm -50 (over temperature range) ± 30 ppm -30 ± 20 ppm -20 ± 10 ppm -10 Circuit Condition: 6 pF ~ 50 pF or series Equivalent Series Resistance: Maximum resistance corresponds to frequency. Please see ESR table. Typically 50 Ω. All dimensions are in mm Marking: Line 1 : XX.XXX - Frequency in MHz (6 digit) Line 2 : YWW - Year and Week No. Drive Level: 10 µW Typical Ordering Information Shunt Capacitance: 7 pF max Aging: ± 2 ppm max per year Optional Features: Fundamental - F 3 rd,5th,7th O.T. - 3, 5, 7 Tape & Reel - T Note: 1. Other frequencies, tolerances, stabilities, and operating temperature ranges available. Consult VTC Support for specific requirements. 2. Not all combinations of the above tolerances, stabilities, and temperature ranges are available. Consult VTC Support if your requirement is not standard. 3. All specifications subject to change without notice.
