Overview
The AI-1027-TWT-5V-2-R is a through-hole electromagnetic audio indicator manufactured by PUI Audio. It operates at a nominal voltage of 5 VDC with a current draw of 30 mA. The device produces a continuous tone at a resonant frequency of 2.73 kHz and delivers a sound pressure level of 82 dBA. Designed for board-mount applications, it features pin termination and supports an operating temperature range from -30°C to +70°C.
Feature Summary
- Electromagnetic transducer design for reliable audio signaling
- Continuous tone output capability for persistent alerts
- Through-hole mounting configuration for standard PCB assembly
Applications
- Electronic equipment status indication
- Appliance control panel feedback
- Industrial instrument alarm systems
Procurement Notes
Verify the specific suffix '2-R' against official datasheets to confirm the exact acoustic and electrical characteristics, as variations exist within the AI-1027 series. Ensure compatibility with through-hole assembly processes and validate that the 5VDC nominal rating aligns with the target circuit supply voltage before integration.
Selection Notes
Select this component when a through-hole electromagnetic indicator is required for 5VDC systems. The 82 dBA output provides clear audibility in moderate noise environments. Consider the physical dimensions and pin spacing to ensure adequate clearance on the printed circuit board layout during the design phase.
Part Context
This part belongs to the AI-1027 family of audio indicators from PUI Audio. These devices are engineered for general-purpose audible signaling in consumer electronics and industrial controls. The electromagnetic technology offers a balance of cost-effectiveness and performance for non-music audio applications.
Replacement Considerations
Cross-reference with other AI-1027 variants such as AI-1027-TWT-5V-R or AT-1224-TWT-5V-2-R only if mechanical footprint and electrical parameters match exactly. Verify frequency and SPL differences to ensure functional equivalence in the final application.
