MQ & MQ2 CRYSTALS  
7 x 5mm SMD, 4 pad or 2 pad  
FEATURES  
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 ±10pppm 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. There are two package variants, 4 pad and two pad.
