Description

The NKS7 Series incorporates a sub-

miniature AT-cut strip crystal resonator

housed in a standard 5x7 mm ceramic

package. These compact crystals are ideal

for surface mount, densely-populated

PCB applications.

Applications & Features

Rugged AT-cut crystal construction

Extremely small SMD package

Ideally suited for disc drives, PCMCIA,

PC's and hand-held products

Available on tape & reel
