18.432MHZ MQ/30/30/40/12PF

EURO QUARTZ 7 x 5mm SMD, 4 pad or 2 pad FEATURES · MQ & MQ2 CRYSTALS 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.
