X21-W CRYSTALS

WI-FI APPLICATIONS

DESCRIPTION

X21-W crystals are ultra-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.
