DESCRIPTION:
This SMD ceramic package has been specially designed for miniature
telecom and portable applications. The Ultra Miniature Quartz Crystal
resonator in this product is achieved by a special manufacturing process
The optimized resonator design "low-ESR and low sensitivity" provide
best-of-its-class electrical performance.
For pick-and-place equipment, the parts are available in 8 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
