AI-550AS

Alarms, Buzzers, And Sirens Overview

The AI-550AS is a through-hole piezo audio indicator manufactured by PUI Audio. It operates at a nominal voltage of 12V DC and features an internally driven buzzer design for direct microcontroller interfacing. The component utilizes PC pin termination for board mounting and emits sound at a resonant frequency of 2.9 kHz. This device is classified as RoHS non-compliant due to lead content, indicating it may be restricted in certain regulated markets or applications requiring full compliance.

Alarms, Buzzers, And Sirens Feature Summary

• Internally driven buzzer circuitry allows for direct connection to logic-level signals without external drivers
• Through-hole mounting style with PC pins ensures secure mechanical attachment to printed circuit boards
• Piezoelectric transducer technology provides reliable acoustic output for audible alerts

Alarms, Buzzers, And Sirens Applications

• Microcontroller-based embedded systems requiring simple audible feedback
• Industrial control panels needing status indication alarms
• Consumer electronic devices utilizing through-hole assembly processes

Alarms, Buzzers, And Sirens Procurement Notes

Verify RoHS compliance requirements before procurement, as this part contains lead and is marked non-compliant. Confirm that the 12V operating voltage matches your system's power supply rails. Ensure PCB footprints accommodate the specific PC pin spacing for through-hole mounting. Check if the obsolete status affects long-term availability or if alternative compliant models are preferred for new designs.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when an internally driven solution simplifies schematic design by removing external driver transistors. The through-hole format is suitable for prototyping or high-reliability applications where mechanical robustness is prioritized over surface area constraints. Consider the 2.9 kHz frequency response against environmental noise levels to ensure audibility. Evaluate the leaded construction against environmental regulations applicable to the final product's destination market.

Alarms, Buzzers, And Sirens Part Context

The AI-550AS belongs to PUI Audio's AI series of audio indicators and buzzers. This series focuses on providing complete alerting solutions with integrated driving electronics. The manufacturer specializes in custom and standard audio components for industrial, medical, and consumer sectors, offering both piezo and electromagnetic technologies for various acoustic needs.

Alarms, Buzzers, And Sirens Replacement Considerations

Check for newer RoHS-compliant equivalents within the AI series if environmental regulations prohibit leaded components. Verify that substitute parts maintain the same 12V operating voltage and 2.9 kHz frequency to ensure identical acoustic performance and interface compatibility.
