“MS49” series Surface Mount Crystals MERCURY Since 1973 Mercury MS49 SMD crystals were developed to address the market needs for low frequency (10 MHz and under) SMD crystals with 2.0 mm package height. The low cost glass ceramics package makes MS49 ideal for hand-held terminal, scanner, hard disc drive and DVD. Premium grade AT-strip crystal plate is mounted on both ends for high shock and low G sensitivity applications. SPECIFICATIONS Crystal Holder Prefix: MS49 series. For compatible foot print with 4.2 mm and 3.2 mm package height please refer to M49 and M49L series 3.2~30.0 MHz AT-cut Fundamental mode Mode of Oscillation: 27.0~70.0 MHz AT-cut 3rd Overtone mode 24.0~48.0 MHz BT-cut Fundamental mode Calibration Tolerance: Frequency Stability: Shunt Capacitance (Co): ±30 ppm (±0.003 %) at 25°C AT-cut: ±30 ppm (±0.003 %) over -10 to +60°C BT-cut: ±100 ppm (±0.01 %) over -10 to +60°C 7 pF maximum Equivalent Frequency Series Resistance 3.2 ~ 3.4 (E.S.R.) 3.5 ~ 4.0 Osc.
