AT-2250-T-LW50-R

Overview

The AT-2250-T-LW50-R is an externally driven piezoelectric transducer manufactured by PUI Audio, Inc. It features a round shape with through-hole PC pin terminations for mounting. The device operates within a voltage range of 1 to 30 volts and produces a noncontinuous tone at a frequency of 5000 Hz. Key performance metrics include a sound pressure level of 92 dB measured at 15V and a sensitivity of 75 dB at 4300 Hz. The unit is designed for high volume output in compact spaces.

Feature Summary

• Externally driven piezoelectric design for superior volume and clarity
• Through-hole mounting with PC pins for secure integration
• Capable of producing noncontinuous tones at specified frequencies

Applications

• Alarm systems requiring high audibility
• Buzzer applications in consumer electronics
• Industrial control panels needing clear audio feedback

Procurement Notes

Verify the specific ordering suffix and termination type against the official datasheet to ensure compatibility with your PCB layout. Confirm that the external driver circuit can supply the required voltage range of 1 to 30 volts. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure the through-hole footprint matches your assembly equipment capabilities.

Selection Notes

Select this component when high sound pressure levels are critical in a small form factor. The externally driven nature allows for flexible waveform generation compared to self-excited buzzers. Consider the 92 dB output at 15V for environments requiring loud alerts. Verify that the 5000 Hz resonant frequency aligns with the desired acoustic profile for your specific application needs.

Part Context

This part belongs to PUI Audio's line of speakers and transducers. It is categorized under alarms, buzzers, and sirens. The product is designed for through-hole mounting on printed circuit boards. It serves as a reliable audio signaling solution for various electronic devices requiring clear and audible notifications.

Replacement Considerations

Consult official substitution guides or manufacturer cross-reference lists for verified alternatives. Ensure any replacement maintains the same voltage range, frequency response, and mounting style. Do not assume interchangeability based solely on physical dimensions without verifying electrical characteristics.
