HANDLING INSTRUCTIONS
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.
Pb
RoHS
Compliant
| | | | | | | | | | | | | | |
(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.
