PT-1403-3

Overview

The PT-1403-3 is an externally driven piezoelectric transducer manufactured by Soberton Inc. It operates at a nominal voltage of 9 V with a current consumption of 3 mA. The device generates an acoustic output of 80 dB measured at 9 V and features a resonant frequency of 5.2 kHz. The physical dimensions include a diameter of 14 mm and a height of 2.85 mm. It is supplied with custom wire leads for direct integration into electronic circuits.

Feature Summary

• Externally driven piezoelectric design
• High acoustic output level
• Custom wire lead configuration

Applications

• Industrial control systems
• Consumer electronics
• Automotive systems
• IoT devices
• Medical equipment

Procurement Notes

Verify the specific suffix -3 indicates custom wire leads rather than standard termination methods. Confirm the operating voltage matches the 9 V requirement to ensure proper acoustic performance. Check datasheet specifications for mounting constraints related to the 14 mm diameter form factor. Ensure environmental ratings align with the intended deployment location.

Selection Notes

Select this component when a high-decibel audible alert is required in space-constrained designs. The 14 mm diameter allows for compact panel or chassis integration. Verify that the driving circuit can supply the necessary 3 mA current at 9 V. Consider the 5.2 kHz frequency response for optimal human audibility in noisy environments.

Part Context

This part belongs to Soberton Inc.'s line of piezoelectric buzzers and sirens. It is distinct from internally driven models as it requires an external oscillator signal. The PT-1403 series offers various configurations, with the -3 suffix denoting specific lead arrangements. It serves as a reliable audio signaling solution for embedded applications.

Replacement Considerations

Direct substitutes must match the 14 mm diameter, 9 V operation, and 80 dB output. Verify pinout compatibility if using pre-wired alternatives. Cross-reference mechanical mounting holes and terminal types. Consult manufacturer cross-reference lists for equivalent piezo transducers with similar acoustic profiles.
