Overview
The AT-1620-TWT-12V-R is an externally driven piezoelectric transducer manufactured by PUI Audio. It operates with a rated voltage of 12 V and accepts peak-to-peak signal inputs within a range of 9 to 15 V. The device produces an acoustic output of 85 dBA at its self-resonant frequency of 2.048 kHz. Designed for compact integration, it functions as an audio indicator or buzzer component suitable for various electronic applications requiring reliable sound generation.
Feature Summary
- Externally driven piezoelectric design for flexible control
- Optimized for 12 V operation with defined input voltage range
- High acoustic output efficiency at resonant frequency
Applications
- Electronic appliance status indicators
- Medical equipment audio alerts
- Industrial control panel signaling
Procurement Notes
Verify the specific suffix designation against official PUI Audio documentation to confirm electrical ratings. Ensure the driving circuitry supports the required peak-to-peak voltage range. Confirm mechanical mounting requirements align with the intended PCB layout. Cross-reference datasheet revisions to guarantee compatibility with current manufacturing standards.
Selection Notes
Select this component when a dedicated driver circuit is available to manage the external drive requirements. Consider the 12 V rating relative to system power availability. Evaluate the 85 dBA output level against ambient noise conditions. Assess the physical dimensions for enclosure fitment compared to alternative transducer sizes.
Part Context
This model belongs to the AT series of electromagnetic and piezoelectric transducers from PUI Audio. The series focuses on providing standardized audio solutions for industrial and consumer electronics. The AT-1620 variant specifically targets applications needing precise frequency generation and moderate sound pressure levels in a compact form factor.
Replacement Considerations
Direct substitutes require matching the 2.048 kHz resonance and 12 V rating. Verify pinout compatibility if replacing on existing PCBs. Check if alternative models offer similar dBA output without exceeding voltage limits.
