ACT1x5, 2x6 & 3x8 Watch Crystal
The ACT1x5, 2x6 & 3x8 are miniature cylindrical packages offering high vibration and shock resistance,
together with high stability. They are suitable for portable equipment and where a close packing density is
required.Two versions are offered, C1BLC: a low cost version and the HQM4E: a version with a higher Q
value. The 1x5 device is only available in the High Q version.

Soldering
Lead wires should be soldered within 10
seconds with a tip temperature not exceeding
270°C.
The device should ideally be upright on the
board.
If the device can is required to be mechanically
affixed to the board it should be stuck down
with rubber adhesive.
Under no circumstances should any solder
connection be made to the can of the device.
Please note that all parameters can not necessarily be specified in the same device
Customer To specify : Frequency Tolerance, Load Capacitance, Operating Temperature Range
In line with our ongoing policy of product evolvement and improvement, the above specification may be subject to change without notice
