12.0MHz to 50MHz

DESCRIPTION

FEATURES

X42 crystals are micro-miniature surface-mount mount crystals. The

crystals have a gold plated ceramic base and 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 specifically designed for use in small hand-held

communication equipment such as PDAs, GPS and Bluetooth.

Miniature size: 4.0mm x 2.5mm x 0.6mm height

Gold-plated ceramic base with metal seam-welded package

Very low ageing

Designed for hand-held equipment, PDAs, Blue Tooth, GPS

High shock and vibration resistance
