AI-1231-TWT-4

Overview

The AI-1231-TWT-4 is a board-mount electromagnetic audio indicator manufactured by PUI Audio. It operates on a 5 VDC voltage rating with a current consumption of 30 mA. The device produces a continuous tone at a resonant frequency of 3.1 kHz and delivers a sound pressure level of 83 dBA. It features through-hole termination for PCB mounting and has a round form factor with a diameter of 12 mm.

Feature Summary

• Electromagnetic transducer design for reliable acoustic output
• Internally driven mechanism simplifies circuit integration
• Through-hole pin termination ensures secure PCB attachment

Applications

• General purpose electronic equipment status indication
• Consumer appliance audible alerts
• Industrial control panel signaling

Procurement Notes

Verify the specific voltage and current requirements against your system design, as the component is rated for 5 VDC and 30 mA. Confirm that the through-hole footprint matches your PCB layout constraints. Ensure compliance with relevant environmental regulations such as RoHS before finalizing procurement decisions.

Selection Notes

Select this component when a compact, internally driven electromagnetic buzzer is required for low-voltage applications. The 12 mm diameter suits space-constrained designs. Consider the 83 dBA output level for environments requiring moderate audibility without excessive power consumption.

Part Context

This part belongs to the AI series of audio indicators from PUI Audio, which includes various piezoelectric and electromagnetic options. The AI-1231-TWT-4 specifically utilizes an electromagnetic driver, distinguishing it from piezoelectric variants in terms of drive circuitry and acoustic characteristics within the same product family.

Replacement Considerations

Direct substitutes may include other 5 VDC electromagnetic buzzers with similar 3.1 kHz frequency and 12 mm diameter. Verify mechanical dimensions and pin spacing to ensure compatibility with existing PCB footprints.
