X32-W CRYSTALS
WI-FI APPLICATIONS
DESCRIPTION
X32-W crystals are micro-miniature surface-mount mount crystals. The
crystals have a gold plated ceramic base with a seam welded metal lid
providing a stable crystal with very low ageing. The rugged construction
ensures that this crystal has high shock and vibration resistance. The
crystal has been optimized for WI-Fi applications: Bluetooth/ Bluetooth
Low Energy (BLE), Bluetooth Smart, Zigbee, ISM, Wi-Fi / WLAN, LPWAN
and others.
