The FX-3 "AT Strip" Crystal features miniaturization which makes

it perfect for applications requiring small size. In terms of volume,

the FX-3 is 75% smaller than the standard HC80 and is 90% smaller

than the HC49U, with the smallest footprint of any crystal package.

FEATURES

• Miniature Package

• Very Small Footprint

• Cost Effective

• Rugged Cold Weld Design

All dimensions are in millimeters.

* Other tolerances, stabilities & operating temperature ranges

available. Consult Fox Customer Service for specific

requirements, or use crystal order form on page 6.

All specifications subject to change without notice.

NOTE: This table shows the Max. stability of the same standard part over different operating temperature ranges.

ex: The same 8.000MHz standard part would have a Max. stability of ±30PPM over -10ºC ~ +60ºC,

±50PPM over -20ºC ~ +70ºC, and ±80PPM over -40ºC ~ +85ºC.
