EURO QUARTZ X42 CRYSTALS 4 x 2.5 x 0.6mm SMD 10.0MHz to 60MHz FEATURES Miniature package: 4.0 x 2.5 x 0.6mm Gold-plated ceramic base with metal seam-welded package Very low ageing Designed for hand-held equipment, PDAs, Blue Tooth, GPS High shock and vibration resistance DESCRIPTION OUTLINE & DIMENSIONS X42 crystals are micro-miniature surface-mount mount crystals. The crystals have a gold plated ceramic base with a seam welded metal lid providing a stable crystal with very low ageing. The rugged construction ensures that this crystal has high shock and vibration resistance. The crystal has been specifically designed for use in small hand-held communication equipment such as PDAs, GPS and Bluetooth.
