General Description

The miniature CX-2-SM AT-cut crystals in leadless ceramic

packages have been designed for surface-mounting on printed

circuit boards or hybrid circuits. These crystal have a low profile

and a very small footprint. Manufactured by a photo-lithographic

process, the CX-2-SM is a robust crystal that has gained

widespread acceptance in the industry.

Full military environmental testing available
