Part Numbering Guide
Description
The NKS6 Series incorporate a sub-min-
iature AT-cut strip crystal resonator
housed in a 3.5x6 mm ceramic package.
These compact crystals are ideal for sur-
face mounting in densely-populated PCB
applications.
Applications & Features
• Tight tolerance & stability
• Rugged construction and excellent
mechanical shock resistance
• Extremely compact SMD package
• Seam sealed, grounded metal lid
• Ideally suited for disc drives, PCMCIA,
PCs and hand-held electronic products
• Available on tape & reel; 12mm tape,
1000pcs per reel
