AT-101Z-3

Overview

The AT-101Z-3 is an electromagnetic transducer manufactured by PUI Audio, Inc. This component operates at a nominal voltage of 3V and delivers a sound pressure level of 90 dB. It features a resonant frequency of 1 kHz and has an impedance of 16 ohms. The device utilizes gullwing lead termination for board mounting applications. Its physical dimensions are 10 mm in length, 10 mm in width, and 4.5 mm in depth. The unit is designed to function within a temperature range of -40°C to +85°C.

Feature Summary

• Electromagnetic transduction mechanism for audio signaling
• Gullwing lead termination for surface mount integration
• High acoustic output efficiency relative to drive voltage

Applications

• Medical equipment status indicators
• Industrial control panel alerts
• Security system notifications
• Consumer electronics feedback signals

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with PUI Audio or authorized distributors before finalizing procurement. Confirm that the gullwing lead pitch matches the target PCB footprint design. Ensure the operating environment remains within the specified -40°C to +85°C thermal limits to maintain performance integrity and longevity of the electromagnetic assembly.

Selection Notes

Select this model when a compact, high-output electromagnetic solution is required for surface-mount assembly. The 16-ohm impedance and 3V rating suit low-voltage digital logic interfaces. Consider the 90 dB SPL capability for applications requiring audible alerts without complex amplification circuits. Evaluate the 1 kHz resonance for optimal tonal clarity in user interface feedback scenarios.
