PT-1625

Overview

The PT-1625 is an externally driven piezoelectric buzzer manufactured by Soberton Inc. Designed for surface mount applications, this component operates at a nominal voltage of 3V with a current consumption of 1mA. It features a resonant frequency of 4kHz and delivers a sound pressure level of 70dB when measured at a distance of 10cm from the source.

Feature Summary

• Externally driven piezoelectric transducer design
• Surface mount solder pad configuration
• Compact 16x16mm form factor

Applications

• Electronic alarm systems
• Audible notification devices
• Consumer electronics indicators

Procurement Notes

Verify the specific package variant and lead time requirements with authorized distributors prior to ordering. Confirm that the external drive circuitry matches the 3V nominal voltage and 1mA current specifications to ensure optimal performance and longevity of the piezoelectric element.

Selection Notes

Select this component for designs requiring a low-profile, surface-mount audible indicator. Ensure the host circuit can provide the necessary external drive signal at 4kHz. Consider the 70dB acoustic output relative to the required audibility in the target application environment.

Part Context

This part belongs to the Soberton Inc. piezoelectric buzzer family, specifically categorized under externally driven transducers. It is distinct from self-oscillating buzzers as it requires an external oscillator or microcontroller to generate the driving frequency.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation.
