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.
