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
