HANDLING INSTRUCTIONS
32.768kHz WATCH CRYSTAL, 6.2 x 02.1MM CYLINDER PACKAGE
Mounting:
(1) Soldering on the body of the cylinder type crystal unit must be strictly avoided due to deteriorate the characteristics or
damage the products. Rubber adhesive is recommended.
(2) When the leads need to be bent by hand, follow the instructions below.
- Hold the body of the Cylinder type crystal unit in fingers.
- Pick at the part with tweezers, which you intend to bend. There should be more than 1.5mm (3.0mm is recommendable)
from the body case.
- Bend the lead 90º by tweezers without pulling the lead strongly. Pulling the leads forcefully may cause cracks in the glass
hermetic seal resulting in component failure.
