DESCRIPTION:
This SMD ceramic package has been specially designed for ultra low profile
telecom and smart-card applications. A special crystal manufacturing
process is used to achieve improved electrical characteristics and a
miniaturized blank size.
The crystals are supplied in special trays (200 crystals per tray).
For pick-and-place equipment, the parts are available in 12 mm tape:
7” (178 mm) reel with 3’000 crystals
10” (254 mm) reel with 7’000 crystals
13” (330 mm) reel with 14’000 crystals
