AI-1027-TWT-3V-R

Overview

The AI-1027-TWT-3V-R is an electromechanical audio indicator manufactured by PUI Audio, Inc. It operates at a rated voltage of 3 VDC with a current draw of 30 mA. The device produces a continuous tone at a frequency of 2.7 kHz and delivers a sound pressure level of 80 dBA. It utilizes through-hole termination for PCB mounting.

Feature Summary

Electromechanical transducer technology
Continuous single-tone output
Through-hole lead termination

Applications

Medical equipment indicators
Industrial control panels
Security and fire alarm systems

Procurement Notes

Verify the specific suffix 'TWT' confirms through-hole gull-wing leads rather than surface mount variants. Confirm the '3V' designation matches the required 3 VDC operating voltage. Ensure the 80 dBA acoustic rating meets environmental noise requirements. Cross-reference the manufacturer part number to avoid confusion with similar electromagnetic models.

Selection Notes

Select this component when through-hole assembly is required for mechanical stability. Choose based on the 2.7 kHz frequency for optimal audibility in standard environments. Verify that the 30 mA current consumption fits within the driving circuit's capacity. Consider the 80 dBA output level relative to enclosure attenuation.

Part Context

This model belongs to PUI Audio's line of board-mount audio indicators. It is distinct from surface mount (SMD) versions like the SMI series. The product line includes various voltage and frequency options for different application needs.

Replacement Considerations

The AI-1027-TWT-3V-R is functionally equivalent to the SMI-1027-TW-3V-R regarding acoustic performance, though package types differ. Direct pin-compatible replacements are not explicitly documented in public sources.
