Overview
The AT-3045-TT-R is an externally driven piezoelectric transducer manufactured by PUI Audio, Inc. Designed for through-hole mounting, this component features PC pin termination and a circular form factor with a 30 mm diameter. It operates at a resonant frequency of 4.5 kHz and delivers a sound pressure level of 97 dBA when driven at 10 V. The device has a voltage rating of 10 V peak-to-peak and a current rating of 12 mA. Its physical dimensions are 30 mm in diameter by 12.2 mm in height.
Feature Summary
- Externally driven piezoelectric design for flexible signal integration
- High acoustic output capability suitable for audible alerting applications
- Through-hole construction with PC pins for robust board attachment
Applications
- Industrial control panel indicators
- Medical equipment status alerts
- Security system sirens and alarms
Procurement Notes
Verify the specific datasheet version to confirm RoHS compliance and REACH SVHC status prior to procurement. Ensure the driving circuit can supply the required 12 mA current at 10 Vpp without exceeding thermal limits. Confirm that the through-hole footprint matches the PCB layout specifications exactly to avoid mechanical interference during assembly.
Selection Notes
Select this component when a high-decibel audible indicator is required for through-hole assemblies. Compare against electromagnetic alternatives if lower power consumption is critical, as piezo elements typically draw minimal current but require higher drive voltages. Consider the 4.5 kHz resonance for optimal efficiency in tone generation circuits.
Part Context
This part belongs to PUI Audio's line of standard piezoelectric transducers. It is distinct from their electromagnetic speakers and ultrasonic receivers. The model number indicates a 30 mm diameter unit within their standard catalog, differentiated from similar models like the AT-3046-TT-R by its specific frequency and acoustic output characteristics.
Replacement Considerations
The AT-3046-TT-R is a comparable alternative offering 95 dBA at 4.6 kHz. Verify that the slight difference in resonant frequency and sound pressure level meets the application requirements before substituting.
