Overview
The AI-1027-TWT-5V-HT-R is a through-hole audio indicator manufactured by PUI Audio, Inc. It operates on a rated voltage of 5 VDC with an operating range of 3 to 6.5 VDC. The device generates a continuous single-tone signal at a frequency of 2.7 kHz. It produces a sound pressure level of 85 dBA and draws current consistent with its electromechanical design.
Feature Summary
- Electromechanical construction utilizing magnetic technology for reliable acoustic output
- Designed for continuous operation mode producing a single tone
- Through-hole mounting configuration for standard PCB integration
Applications
- Electronic equipment requiring audible status indicators
- Control panels needing high-temperature tolerant audio signals
- Appliance systems requiring continuous tone alerts
Procurement Notes
Verify the specific HT suffix designation against official PUI Audio documentation to confirm high-temperature rating specifications. Ensure the through-hole package dimensions match the target PCB footprint. Confirm that the 3 to 6.5 VDC operating range aligns with the system power supply constraints before finalizing procurement.
Selection Notes
Select this component when a through-hole solution is required for high-frequency audio indication. The 2.7 kHz frequency provides distinct audibility compared to lower tones. Verify that the 85 dBA output meets environmental noise requirements. Ensure the physical size accommodates the assembly space and that the voltage range supports the circuit design.
Part Context
This part belongs to the AI-1027 series of audio indicators from PUI Audio. The series includes various voltage ratings and mounting styles. The TWT designation indicates through-hole technology, while the HT suffix typically denotes enhanced thermal performance characteristics within the product line.
Replacement Considerations
Cross-reference with AI-1027-TWT-5V-R for standard temperature variants. Check AI-1027-TWT-3V-R if lower voltage operation is acceptable. Verify pinout compatibility and mechanical dimensions before substituting any alternative models.
