DESCRIPTION:
This SMD ceramic package has been specially designed for miniature
high-reliable applications including implantable medical devices.
The Ultra Miniature Tuning Fork (UMTF) in this product is realized by an
optimized, proprietary design of the Quartz Crystal Resonator and special
manufacturing processes resulting in improved electrical characteristics
"Low ESR and Low Sensitivity".
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
