PT-1540PQ

Overview

The PT-1540PQ is a piezoelectric buzzer from the Mallory Sonalert PT series, designed for through-hole mounting. It operates at a rated voltage of 5 VDC and draws a current of 5 mA. The device produces a continuous tone at a frequency of 3 kHz with a sound pressure level of 95 dBA. Its compact dimensions are 17 mm in diameter and 6 mm in height, featuring solder pin termination for PCB integration.

Feature Summary

• Piezoelectric transducer technology for reliable audio signaling
• Continuous tone output capability
• Through-hole solder pin termination for printed circuit board assembly

Applications

• Industrial control panels
• Medical equipment indicators
• Consumer electronics status alerts

Procurement Notes

Verify the specific acoustic characteristics against the official Mallory Sonalert datasheet to ensure compliance with project requirements. Confirm that the 5 VDC operating voltage aligns with the target system power supply. Ensure the through-hole footprint matches the design layout before finalizing procurement orders.

Selection Notes

Select this component when a low-profile, 5 VDC driven buzzer is required for panel or board mounting. The 95 dBA output provides clear audible indication in moderate noise environments. Consider the 17 mm diameter constraint for enclosure space limitations compared to larger industrial alarm models.
