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

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.
