- Industrial control panel indicators
- Consumer electronics status signaling
Procurement Notes
Verify the specific datasheet version for the AT-2830-TWT-R to confirm exact electrical tolerances and mechanical dimensions before integration. Ensure the PCB layout accommodates the 28.5 mm diameter and through-hole pin spacing. Confirm that the target application environment remains within the specified -30°C to +85°C operating temperature range to maintain performance reliability.
Selection Notes
Select this component when a high-decibel audible signal is required without active driving circuitry complexity. The wide voltage range allows flexibility in power supply design. The through-hole package is suitable for robust mechanical attachment in industrial or consumer environments where surface-mount space is not a constraint.
Part Context
This part belongs to the PUI Audio piezoelectric transducer family. It is designed as a direct replacement for other 28.5 mm diameter piezo buzzers in existing designs. The product line focuses on providing reliable audible signaling solutions with varying sound pressure levels and mounting configurations.
Replacement Considerations
Check mechanical compatibility with existing PCB footprints. Verify that the new part's resonant frequency matches the original design requirements. Ensure the replacement supports the same voltage range and mounting style.
