5. Note
1. Only the lead should be heated when soldering.
In case that the package temperature is exceeding 150°C , it may impair the crystal or may
cause the crystal quartz to destroy.
2. Pulling the lead strongly may cause cracking of the hermetic grass seal bending the lead
closely from the case may also cause same problem, so when the lead needs to be bent,
please leave move than 05.mm of lead from the case.
3. Too much shock or vibration is not allowed. According to conditions such as machine shock
during the assembly, the internal quartz crystal might be damaged.
Please check your conditions carefully when using it in advance.
4. Don't storage or use in the environment that temperature may change rapidly to avoid the
condensation. And also we recommend to storage the products in the normal environment.
(Temperature, humidity)
5. This product can be subjected to ultrasonic cleaning. However, since the oscillator may be
affected depending on the condition, be sure to check it.
6. Applying excessive drive level to the quartz crystal may cause deterioration for characteristics
or damage.
Circuit design must be such as to maintain a proper drive level.
7. Unless adequate negative resistance is allocated in the oscillation circuit, startup time of
oscillation may be increased or no oscillation may occur. In order to avoid this, provide enough
negative resistance in the circuitry design.
