AST1640MACTRQ

Overview

The AST1640MACTRQ is a piezoelectric audio transducer manufactured by Mallory Sonalert. It operates at a nominal voltage of 3 V with a current rating of 8 mA. The device produces a sound pressure level of 90 dB at a frequency of 4 kHz. Its physical dimensions are 16 mm x 16 mm x 2.5 mm, utilizing SMD/SMT termination for surface mount assembly. This component belongs to the AST series and is supplied in tape and reel packaging.

Feature Summary

• Piezoelectric transduction mechanism for reliable acoustic output
• Surface mount design compatible with automated assembly processes
• Compact form factor suitable for space-constrained applications

Applications

• Electronic equipment status indication
• Consumer appliance alert systems
• Industrial control panel signaling

Procurement Notes

Verify the specific suffix 'CTRQ' confirms tape and reel packaging requirements against standard bulk variants. Ensure the 3 VDC operating voltage aligns with target circuit designs. Confirm RoHS compliance documentation is available for regulatory adherence. Validate that the 4 kHz frequency meets auditory detection needs for the intended environment.

Selection Notes

Select this component when surface mount technology is required for the AST series. Compare the 90 dB output against lower decibel models if volume constraints exist. Consider the 16x16 mm footprint against smaller alternatives like the AST1240MLQ if board space is limited. Verify compatibility with 3 V logic or power rails before integration into the final assembly.

Part Context

This part is a variant within the Mallory Sonalert AST family of piezoelectric buzzers. It shares core electrical specifications with the AST1640MACQ but differs in packaging format. The AST series provides standardized acoustic solutions for various industrial and consumer applications requiring compact, low-power audible alerts.

Replacement Considerations

AST1640MACQ serves as the bulk packaging equivalent with identical electrical characteristics.
