AT-1220-TT-8-R

Overview

The AT-1220-TT-8-R is an electromagnetic transducer manufactured by PUI Audio, Inc. It operates within a supply voltage range of 1 to 2 V and features a resonant frequency of 2.048 kHz. The device produces a sound pressure level of 80 dBA at 1.5 V measured from a distance of 10 cm. Electrical characteristics include a current rating of 20 mA. The component utilizes through-hole mounting technology for PCB integration.

Feature Summary

Electromagnetic transducer design for single-tone audio indication
Top-fire acoustic output configuration
Through-hole mounting for secure board attachment

Applications

Electronic device status indicators
Simple alarm systems
User interface feedback mechanisms

Procurement Notes

Verify the specific electrical parameters against the manufacturer's datasheet before implementation. Confirm that the operating voltage aligns with the 1 to 2 V range and that the 20 mA current draw is supported by the driving circuit. Ensure mechanical compatibility with the through-hole footprint dimensions specified in the official documentation.

Selection Notes

Select this component when a low-voltage, single-frequency audible alert is required. The 2.048 kHz frequency provides a distinct tone suitable for basic notification tasks. Consider the 80 dBA output level relative to the enclosure acoustics. The through-hole package is appropriate for standard prototyping or high-reliability assembly processes.

Part Context

This part belongs to the PUI Audio electromagnetic transducer series. It is designed for cost-effective audio signaling applications. The product line emphasizes reliable performance in consumer electronics and industrial control panels where simple tonal alerts are sufficient.
