AST1240MLQ

Overview

The AST1240MLQ is an external drive piezoelectric transducer manufactured by Mallory Sonalert. Designed for surface mount technology (SMD/SMT) applications, this component features a compact rectangular footprint measuring 12 mm in length, 12 mm in width, and 3 mm in height. It operates at a rated voltage of 3 V with a current consumption of 5 mA. The device generates an acoustic signal at a frequency of 4 kHz with a sound pressure level of 75 dB. Electrical connections are established via solder pads, facilitating automated assembly processes.

Feature Summary

Surface mount construction utilizing solder pad termination for PCB integration
Piezoelectric transduction mechanism driven by external circuitry
Compact low-profile physical design suitable for space-constrained layouts

Applications

General electronic equipment status indication
Low-voltage battery-operated device alerts
Consumer electronics audio signaling

Procurement Notes

Verify the specific suffix and revision code against the manufacturer's latest datasheet to ensure compatibility with required operating voltages and acoustic specifications. Confirm RoHS compliance documentation is available for regulatory adherence. Check for any recent engineering change notices that may affect pinout or material composition prior to finalizing procurement orders.

Selection Notes

Select this component when a low-profile surface mount solution is required for 3 V systems. Ensure the driving circuit can supply the specified 5 mA current. Consider the 75 dB output level relative to ambient noise requirements. Verify that the 4 kHz frequency aligns with human hearing sensitivity for the intended alert application.

Part Context

This part belongs to the AST series of audio indicators from Mallory Sonalert. The series focuses on miniature piezoelectric transducers designed for board-level mounting. These components serve as fundamental audible alert elements in various electronic assemblies requiring simple, reliable sound generation without internal oscillators.
