QUARTZ

5.0 x 3.2 x 0.9mm SMD

FEATURES

Miniature size: 5.0mm x 3.2mm x 0.9mm height

2 pad version

High shock and vibration resistance

Ideal for PDAs, GPS, PCMCIA, Wireless LAN etc.

MJ2 CRYSTALS

8.0MHz to 150MHz

DESCRIPTION

MJ2 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.
