AI-278

Overview

The AI-278 is an internally driven piezo indicator manufactured by PUI Audio, Inc. It operates at a nominal voltage of 12 VDC and produces a sound pressure level of 87 dBA at a frequency of 1800 Hz. The component utilizes through-hole mounting with PC pins for board integration. It is classified under buzzers and audio indicators.

Feature Summary

Internally driven piezoelectric technology
Through-hole PC pin termination
High acoustic output capability

Applications

Electronic alarm systems
Audio indication circuits
Control panel signaling

Procurement Notes

Verify the specific datasheet version to confirm RoHS compliance status, as some sources indicate lead content. Ensure the ordering suffix matches the required terminal configuration. Cross-reference the manufacturer part number with distributor listings to confirm current availability and exact electrical specifications before procurement.

Selection Notes

Select this component when a high-volume, low-cost audible signal is required. The 12V rating suits standard logic-level power supplies. Through-hole packaging is suitable for prototyping or high-reliability applications where surface-mount processes are not utilized. Verify space constraints for the PCB footprint.

Part Context

This part belongs to the alarms, buzzers, and sirens category within PUI Audio's portfolio. It serves as a basic audio notification device. The product line focuses on cost-effective solutions for consumer electronics and industrial equipment requiring simple auditory feedback mechanisms.

Replacement Considerations

Check for compatible internally driven piezo buzzers with similar 12V ratings and 87+ dBA output. Ensure replacement parts maintain the same through-hole pin spacing and physical dimensions for direct board compatibility without mechanical modification.
