• High acoustic output capability suitable for audible alert applications

Alarms, Buzzers, And Sirens Applications

• Industrial equipment status indicators
• Consumer appliance alarm systems
• Medical device audio alerts

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific datasheet version as specifications may vary between sources. Confirm that the application circuit provides the necessary drive signal, as this component is an externally driven transducer rather than a self-contained buzzer. Ensure mechanical clearance accommodates the specified height and pin configuration during PCB layout.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when high sound pressure levels are required in a compact through-hole package. Consider the need for an external driver circuit, as this part does not contain internal oscillation electronics. Evaluate thermal constraints against the specified operating temperature range to ensure reliability in the target environment.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the Same Sky piezoelectric transducer family, formerly associated with CUI Devices. It represents a standard industrial-grade audio indicator designed for robust performance. The product line emphasizes reliable acoustic signaling across various electronic assemblies where visual cues are insufficient or prohibited.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes must match the 3 kHz resonant frequency, 108 dB SPL, and through-hole PC pin form factor. Verify voltage compatibility within the 6VDC to 16VDC range. Cross-reference mechanical dimensions to ensure fitment without modifying the existing PCB footprint.
