PT-1303T

Overview

The PT-1303T is a piezoelectric buzzer from Soberton Inc. designed for panel mounting with flange and wire leads. It operates at a nominal voltage of 5 V with a current consumption of 5 mA. The device produces an acoustic output of 75 dB at a fundamental frequency of 4 kHz. It does not include a built-in drive circuit, requiring external driving electronics.

Feature Summary

• Piezoelectric transducer technology
• Panel mount configuration with flange
• Wire lead termination

Applications

• Electronic alarm systems
• Audible status indicators
• Control panel feedback devices

Procurement Notes

Verify the specific part number PT-1303T against official Soberton Inc. documentation to confirm electrical parameters and mechanical dimensions. Ensure compatibility with external drive circuits as the unit lacks internal oscillation. Confirm package type and lead style match system requirements before procurement.

Selection Notes

Select this component when a simple, low-voltage audible indicator is required without integrated driver complexity. Consider the 5 V operating voltage and 5 mA current draw for power budgeting. Evaluate the 75 dB sound pressure level against ambient noise conditions to ensure adequate audibility for the intended application environment.

Part Context

This component belongs to the PT Series of audio products manufactured by Soberton Inc. The series includes various piezoelectric buzzers with different voltage ratings and acoustic outputs. The PT-1303T represents a specific variant within this lineup characterized by its 5 V operation and 4 kHz frequency response.

Replacement Considerations

The PT-1303 is a related model in the same series but operates at 10 V with an 80 dB output and 4800 Hz frequency. Verify if the higher voltage rating and different acoustic characteristics are acceptable substitutes for the PT-1303T application.
