ACT320SMX-4  
The ACT320SMX-4 is a low cost, 4 pad, high quality, low aging 3X2.5mm SMD Crystal in a  
ceramic base / metal lid package, seam welded for good long term reliability. The device has the  
lid grounded via the package to reduce EMI issues. The wide frequency range and specification  
options  
ensure  
suitability  
for  
many  
applications.  
.
APPLICATIONS: Bluetooth, WLAN, PDA, Pagers, Card readers, Cellular, PC Accessories,  
Notebook, Audio-visual, PCMCIA, MP3, Consumer & Communications.
