EURO
QUARTZ
5 x 3.2 x 0.9mm SMD
FEATURES
Miniature size: 5.0mm x 3.2mm x 1.0mm height
Gold-plated ceramic base with metal seam-welded lid
To minimize EMI the whole crystal may be grounded
High shock and vibration resistance
Ideal for PDAs, GPS, PCMCIA, Wirless 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.
