Overview
The AI-2438-TT-R is a piezoelectric transducer manufactured by PUI Audio, Inc. It operates at a resonant frequency of 3.8 kHz and delivers a sound pressure level of 95 dBA when driven at 12 VDC. The device has a current rating of 12 mA and accepts an input voltage range of 8 to 18 VDC. It features through-hole solder pin termination and is designed for continuous single-tone operation.
Feature Summary
- Internally driven piezoelectric technology for simplified circuit integration
- Through-hole mounting with solder pin termination for secure board attachment
- Continuous single-tone output capability for consistent audio signaling
Applications
- Electronic alarm systems requiring audible alerts
- Industrial control panels for status indication
- Consumer appliance user interface feedback
Procurement Notes
Verify the specific electrical parameters against the official manufacturer datasheet before finalizing design specifications. Confirm that the through-hole footprint and pin configuration match the target PCB layout requirements. Ensure the operating temperature range aligns with the environmental conditions of the intended application environment.
Selection Notes
Select this component when a self-contained, internally driven indicator is required to reduce external driver complexity. The 12 VDC nominal rating suits standard logic-level power supplies. Consider the 95 dBA acoustic output relative to ambient noise levels in the deployment area to ensure adequate audibility without excessive distortion or power consumption.
Part Context
This part belongs to the PUI Audio piezoelectric transducer family, specifically designed as an audio indicator. It integrates the driving electronics within the package, distinguishing it from passive buzzers that require external oscillators. The model designation indicates its physical form factor and electrical characteristics within the manufacturer's catalog.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with existing drivers if substituting with similar internally driven models from other manufacturers.
