MQ CRYSTALS FEATURES 7 x 5mm SMD, 4 pad Miniature size: 7.0mm x 5mm x 1.2mm height Gold-plated ceramic base with metal seam-welded lid To minimize EMI the whole crystal may be grounded Tight tolerance of 10 ppm for telecommunications use High shock and vibration resistance Ideal for PDAs, GPS, PCMCIA and hand-held equipment OUTLINE & DIMENSIONS MQ DESCRIPTION Miniature surface-mount MQ crystals are produced using a ceramic substrate and fitted with a hermetically-sealed metal lid. The crystals are competitively priced, well-suited to mass-market electronic applications and may also be produced to close tolerances making this crystal a good choice for applications requiring low mass and tight tolerances.
