Overview
The AI-1223-TWT-5V-R is a piezoelectric buzzer manufactured by PUI Audio, designed for board-mounted applications. It operates at a nominal voltage of 5 VDC with a continuous tone output. The device features a 12 mm diameter and utilizes solder pin termination for through-hole installation. Key electrical specifications include a self-resonant frequency of 2.3 kHz and a sound pressure level of 85 dBA. The unit weighs approximately 0.6 grams and functions within a temperature range of -20°C to +70°C.
Feature Summary
- Piezoelectric transducer technology for reliable acoustic signaling
- Self-drive capability allowing direct connection to DC power sources
- Through-hole mounting style with solder pin termination
- Compact cylindrical form factor suitable for space-constrained designs
Applications
- Electronic equipment status indicators
- Appliance operational alerts
- Consumer electronics audio feedback
- Industrial control panel signaling
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required voltage and acoustic parameters. Confirm that the through-hole package dimensions align with the target PCB layout. Check RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as these details are subject to change and are not included in static technical specifications.
Selection Notes
Select this component when a low-profile, self-driven audible indicator is required for 5 VDC systems. The 2.3 kHz frequency provides a distinct alert tone suitable for human hearing. Ensure the application environment stays within the specified operating temperature range. Consider the 85 dBA output level relative to ambient noise requirements before finalizing the design integration.
Part Context
This part belongs to the AI series of piezoelectric buzzers from PUI Audio. It shares mechanical similarities with other 12 mm diameter models but differs in electrical ratings. The AI series is characterized by its robust construction and consistent performance across various consumer and industrial audio indication tasks.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching voltage, frequency, and physical dimensions with alternative manufacturers.
