Tuning fork crystal in 3 x 8 mm cylinder type 32.768 KHz standard ±20 ppm Standard Excellent Reliability Performance
Mounting of cylinder type products:
Soldering the body of the cylinder type crystal units with PCB must be avoided due to deteriorate the characteristics or damage
the products. Rubber adhesive is recommended.
Soldering Lead wires should be soldered within 3 seconds with the soldering iron
heated to a temperature no higher than 300℃
