Procurement Notes

Verify the specific manufacturing date code and lot number upon receipt to ensure compliance with current environmental regulations. Confirm that the receiving facility has appropriate handling procedures for piezoelectric components to prevent mechanical damage during storage. Ensure that the ordering documentation matches the exact suffix designation to guarantee correct acoustic characteristics and terminal configuration for the intended application design.

Selection Notes

Select this component when a low-profile, externally driven acoustic signal is required for general applications. Consider the 14mm diameter constraint for enclosure space planning. Evaluate the 70dB output against ambient noise levels to ensure adequate audibility. Verify that the driving circuit can supply the necessary AC voltage without exceeding the maximum rating to maintain reliability and performance stability over the operational temperature range.
