PT-1507

Overview

The PT-1507 is a surface-mount piezoelectric buzzer manufactured by Soberton Inc. It operates on an externally driven transducer principle with a resonant frequency of 5kHz. The device accepts a peak-to-peak signal input within a voltage range of 1 to 20 volts. It delivers a sound pressure level of 85dB at 12V measured at a distance of 10cm. The unit features a cylindrical form factor with dimensions of 14.8x14.8mm and is designed for washable reflow soldering processes.

Feature Summary

• Externally driven piezoelectric transducer design
• Compatible with washable reflow soldering processes
• Surface-mount package configuration

Applications

• Electronic alarm systems
• Audible status indicators
• Consumer appliance signaling

Procurement Notes

Verify the specific datasheet version when sourcing, as documentation may indicate end-of-life or obsolescence statuses. Confirm RoHS3 compliance requirements against current regulatory standards. Ensure the external drive circuitry can supply the necessary peak-to-peak signal characteristics to achieve the specified acoustic output levels without exceeding the maximum voltage limits.

Selection Notes

Select this component when a compact, surface-mount audible indicator is required for PCB assembly. The externally driven nature allows for flexible frequency control beyond the fixed resonant point if needed, though optimal performance is achieved near 5kHz. Consider the 85dB SPL rating for environments requiring moderate volume. The washable reflow capability supports automated manufacturing workflows.

Part Context

This part belongs to the Soberton Inc. family of piezoelectric buzzers. It is categorized under alarms, buzzers, and sirens. The PT-1507 shares the externally driven transducer architecture common to this series, distinguishing it from internally driven oscillator types. It is designed for integration into electronic assemblies requiring reliable, low-profile audible feedback.
