EURO QUARTZ MJ2 CRYSTALS 5 x 3.2 x 0.9mm SMD 7.0MHz to 50MHz FEATURES Miniature size: 5.0mm x 3.2mm x 1.0mm height 2 pad version High shock and vibration resistance Ideal for PDAs, GPS, PCMCIA, Wirles LAN etc. DESCRIPTION MJ crystals are miniature surface-mount crystals produced with a ceramic substrate and seam-welded metal lid. Their compact size and low mass make hem an ideal crystal for high-density applications.
