ACT31  
The ACT31 is a compact crystal resonator offering high vibration and shock resistance  
together with high stability. It is most suitable for portable equipment and close packing  
density. The device is offered with frequencies between 3.5 and 4.0MHz.

SOLDERING of CYLINDER CRYSTALS  
Lead wire should be soldered within 5 seconds with the iron having a tip temperature of less than 270°C. Case  
must not exceed 150°C  
With regard to wave soldering it is recommended that the process is carried out with the crystal unit set upright on  
the circuit board. Should the process be carried out with the crystal unit on its side then steps must be taken to  
prevent heat transfer through the can.  
Should the whole crystal unit be heated (in a re-flow oven for example) it will result in amarked deterioration of the  
performance or even failure to oscillate. This is due to the internal construction of the crystal unit which involves  
the use of solder.  
Please note that all parameters can not necessarily be specified in the same device
