PT-1640PAQ

Overview

The PT-1640PAQ is an externally driven piezoelectric transducer manufactured by Mallory Sonalert. Designed for board-mount applications, this component operates at a nominal voltage of 5 VDC with a current draw of 1.5 mA. It generates an acoustic output of 85 dB measured at 5 V and a distance of 10 cm. The device functions at a resonant frequency of 4 kHz. Electrical connections are established via through-hole PC pins, facilitating integration into printed circuit boards.

Feature Summary

• Externally driven piezoelectric transducer design
• Through-hole PC pin termination for board mounting
• High acoustic output level relative to low power consumption

Applications

• Electronic equipment status indication
• Low-power audible alert systems
• Consumer electronics signaling

Procurement Notes

Verify the specific ordering suffix against the official Mallory Sonalert datasheet to ensure correct electrical characteristics and mechanical configuration. Confirm that the through-hole package style matches the target PCB footprint requirements. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before procurement.

Selection Notes

Select this component when a compact, low-current piezoelectric solution is required for board-level audio signaling. The 5 V operating voltage makes it suitable for logic-level powered circuits. Ensure the application environment does not require hermetic sealing or extreme environmental protection, as this is a standard board-mount transducer without specified ingress protection ratings.

Part Context

This part belongs to the Mallory Sonalert family of audio indicators and speakers. The brand is recognized for providing sound solutions across industrial, consumer, transportation, medical, and military markets. The PT series represents their range of piezoelectric transducers designed for direct integration into electronic assemblies.

Replacement Considerations

Mallory Sonalert provides cross-reference sheets for obsolete Murata buzzers. Verify if the PT-1640PAQ serves as a direct replacement for any discontinued components in existing designs by consulting the official Mallory Sonalert cross-reference documentation.
