DESCRIPTION:
Lowest profile SMT ceramic pack.
Ultra low profile: 0.50 mm height
SMD-package in Tape and Reel
Ind. and Ext. temperature ranges
High stability
Low aging
Low power consumption
High shock and vibration resistance
ThisSMDceramicpackagehasbeenspeciallydesignedforultralowprofile
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
