DESCRIPTION:
This SMD ceramic package with metal lid has been specially designed
for miniature industrial, telecom and portable applications.
This part is specially designed for Low ESR to support critical oscillator-
circuitries and is available for extended operating temperature range
and is compliant with the AEC-Q200 quality standards for automotive
applications. A special crystal manufacturing process is used to achieve
low ESR in combination with miniaturized blank size.
For pick-and-place equipment, the parts are available in 12 mm tape:
7” (178 mm) reel with 1’000 crystals
7” (178 mm) reel with 3’000 crystals
13” (330 mm) reel with 14’000 crystals
