DESCRIPTION:
All dimensions in mm typical
This SMD ceramic package has been specially designed for small
industrial, telecom and electronic applications. All frequencies are
generated in fundamental mode.
The crystals are supplied in special trays (100 crystals per tray).
For pick-and-place equipment, the parts are available in 16 mm tapes:
7” (178 mm) reel with 1’000 crystals
13” (330 mm) reel with 4’000 crystals
