100% leadfree, RoHS - compliant

All dimensions in mm typical

DESCRIPTION:

Lowest profile SMT ceramic pack.

Ultra low profile: 0.38 mm height

SMD-package in Tape and Reel

Ind. and Ext. temperature ranges

High stability

ThisSMDceramicpackagehasbeenspeciallydesignedforultralowproﬁle

telecom and smart-card applications. A special crystal manufacturing

process is used to achieve improved electrical characteristics and a

miniaturized blank size.

Low aging

Low power consumption

High shock and vibration resistance

For pick-and-place equipment, the parts are available in 12 mm tape:

7” (178 mm) reel with 3’000 crystals

13” (330 mm) reel with 14’000 crystals
