AT-1220-TT-3-R

Overview

The AT-1220-TT-3-R is a magnetic transducer manufactured by PUI Audio, Inc. It operates at a resonant frequency of 2048 Hz with a rated voltage of 1.5 VDC and a peak-to-peak voltage of 1.5 V. The device produces a sound pressure level of 73 dBA. It features through-hole solder pin termination for PCB mounting. Physical dimensions are approximately 12 mm in diameter and 5.5 mm in depth.

Feature Summary

• Magnetic transducer technology for audio indication
• Through-hole solder pin termination for secure PCB mounting
• Single-tone operation mode

Applications

• Electronic device status indicators
• Alarm systems requiring audible alerts
• Consumer electronics audio signaling

Procurement Notes

Verify the specific suffix '3-R' against official datasheets to confirm exact acoustic and electrical tolerances. Ensure compatibility with existing PCB footprints for through-hole assembly. Confirm RoHS compliance status via manufacturer documentation before integration into regulated products.

Selection Notes

Select this component when a low-voltage (1.5V) magnetic buzzer is required. The 2048 Hz frequency provides a distinct tone suitable for general alerting. Consider the 73 dBA output level relative to enclosure acoustics. Through-hole mounting dictates board layout constraints compared to surface-mount alternatives.

Part Context

This part belongs to the AT series of transducers from PUI Audio, Inc. The series includes various electromagnetic and piezoelectric options. The AT-1220-TT-3-R specifically utilizes magnetic technology, distinguishing it from piezoelectric variants within the same product family.

Replacement Considerations

Direct substitutes include the AT-1220-TT-2-R and AT-1220-TT-R from the same manufacturer. Verify that replacement parts match the 2048 Hz frequency and 1.5V rating to ensure functional equivalence.
