## **DESCRIPTION:** 

This SMD ceramic package has been specially designed for miniature telecom and portable applications. A special crystal manufacturing process is used to achieve improved electrical characteristics and a miniaturized blank size. 

The crystals are supplied in special trays (200 crystals per tray). For pick-and-place equipment, the parts are available in 12 mm tape: 7” (178 mm) reel with 3’000 crystals 

13” (330 mm) reel with 14’000 crystals
