MINIATURE SMD CRYSTAL
General Description
The miniature CX-1-SM crystals in leadless ceramic packages have
been designed for surface-mounting on printed circuit boards or
hybrid circuits. Hermitically sealed in a rugged, miniature ceramic
package, the CX-1-SM crystal is manufactured using a photo-
lithographic process.
