“MS2” series Surface Mount Crystals MERCURY Since 1973 MS2 features glass-to-metal substrate and resistance welded metal lid. It has improved hermetic property compared with the obsolete MS series. MS2 was developed to address the market requirements for low frequency (10 MHz and under) with low profile (2.0 mm max) SMD package. Premium grade AT-strip crystal plate is mounted on both ends for high shock and low G sensitivity applications.
