DESCRIPTION:
This SMD ceramic package has been specially designed for small,
implantable medical, industrial, telecom and electronic applications.
All frequencies are generated in fundamental mode.
The crystals are supplied in special trays (200 crystals per tray).
For pick-and-place equipment, the parts are available in 12 mm tapes:
7” (178 mm) reel with 3’000 crystals
13” (330 mm) reel with 14’000 crystals
