The ACT2x6HRSMX is a miniature surface mount Watch Crystal in a cylindrical

package offering high vibration and shock resistance together with high stability.

This device is very suitable for many real time applications including portable

equipment/hand held units and applications that require close packing density of

components, it can also be re-flow soldered to 260°C.
