Remarks



SAW devices should not be used in any type of fluid such as water, oil, organic solvent, etc.



Be certain not to apply voltage exceeding the rated voltage of components.



Do not operate outside the recommended operating temperature range of components.



Sudden change of temperature shall be avoided, deterioration of the characteristics can occur.



Be careful of soldering temperature and duration of components when soldering.



Do not place soldering iron on the body of components.



Be careful not to subject the terminals or leads of components to excessive force.



SAW devices are electrostatic sensitive. Please avoid static voltage during operation and storage.



Ultrasonic cleaning shall be avoided. Ultrasonic vibration may cause destruction of components.
