AI-3039

Overview

The AI-3039 is a piezoelectric buzzer manufactured by PUI Audio, Inc. It operates on a 12V DC supply with a current draw of 15mA. The device produces a continuous tone at a resonant frequency of 3.9kHz. It achieves a sound pressure level of 100dB measured at 12V and 10cm distance. The component supports an operating voltage range from 3VDC to 24VDC.

Feature Summary

• Internally driven piezoelectric technology for single-tone operation
• Board mount configuration suitable for direct circuit integration
• Continuous tone generation capability

Applications

• Industrial alarm systems
• Electronic equipment status indicators
• Consumer appliance audio signaling

Procurement Notes

Verify the specific suffix variant required, such as AI-3039-TWT-12V-R, against the datasheet to ensure correct voltage and mounting specifications. Confirm RoHS compliance status through official documentation before procurement. Ensure the selected part matches the intended board mount application requirements.

Selection Notes

Select this component when a 12V piezo buzzer with high acoustic output is needed. The 100dB SPL rating makes it suitable for noisy environments. Verify that the 3.9kHz frequency aligns with the system's audible alert requirements. Check compatibility with the available PCB space for board mount installation.

Part Context

This part belongs to the PUI Audio piezoelectric buzzer family. These devices are designed for reliable audio indication in various electronic assemblies. The series offers standardized mounting options and consistent acoustic performance across different operating voltages within the specified range.

Replacement Considerations

Direct substitutes include variants like AI-3039-TWT-12V-R which share identical electrical characteristics. Verify pinout and physical dimensions match the existing footprint before substitution.
