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.
