Overview
The AI-1223-TWT-12V-3-R is a piezoelectric audio indicator manufactured by PUI Audio, Inc. It operates at a rated voltage of 12 VDC with a current draw of 8 mA. The device produces a continuous tone at a frequency of 2.9 kHz and achieves a sound pressure level of 95 dBA. It features solder pin termination for through-hole mounting on printed circuit boards. The component has a circular form factor with a diameter of 23.8 mm and a height of 16 mm.
Feature Summary
- Internally driven piezoelectric design for direct connection to control circuits
- Through-hole solder pin termination for secure PCB integration
- Continuous tone output optimized for audible status indication
Applications
- Electronic equipment status indicators
- Appliance alarm systems
- Industrial control panel alerts
Procurement Notes
Verify the specific electrical parameters against the official manufacturer datasheet before integration. Confirm that the 12 VDC rating and 2.9 kHz frequency align with the target system requirements. Ensure the through-hole package dimensions fit the designated PCB layout. Check for RoHS compliance documentation if required by project specifications.
Selection Notes
Select this component when a high-volume, low-cost piezoelectric indicator is needed for 12 VDC systems. The internally driven nature simplifies circuit design by eliminating external oscillators. Consider the 95 dBA acoustic output for environments requiring clear auditory feedback. The standard through-hole format supports automated assembly processes.
Part Context
This part belongs to the AI series of audio indicators from PUI Audio, Inc. The series includes various voltage and frequency options to suit different application needs. The AI-1223-TWT-12V-3-R specifically targets 12 VDC applications requiring a 2.9 kHz tone. It is distinct from electromagnetic transducers in its piezoelectric construction.
Replacement Considerations
Cross-reference with other PUI Audio AI-1223 variants for different voltage or frequency requirements. Verify mechanical compatibility with existing PCB footprints when substituting. Ensure acoustic performance meets minimum threshold requirements for the intended environment.
