AST0927ME-05TRQ

Overview

The AST0927ME-05TRQ is a surface-mount magnetic buzzer manufactured by Mallory Sonalert Products Inc. It operates at a nominal voltage of 5V with a current draw of 80mA. The device produces a sound pressure level of 85dB measured at 10cm distance and functions at a frequency of 2.731kHz. It utilizes an externally driven magnetic technology and features solder pad termination for PCB integration.

Feature Summary

• Externally driven magnetic transducer technology
• Surface mount package with solder pad termination
• High acoustic output capability

Applications

• Electronic equipment status indication
• Alarm systems requiring compact form factors
• Industrial control panel signaling

Procurement Notes

Verify the specific suffix TRQ to confirm tape and reel packaging requirements against your assembly line specifications. Ensure the external drive circuitry can supply the required 80mA current at 5V. Confirm that the 2.731kHz frequency aligns with your audible alert design goals before finalizing procurement.

Selection Notes

Select this component when a high-volume surface-mount solution is required for magnetic buzzer applications. The 8.7x8.7mm footprint suits space-constrained designs. Consider the externally driven nature, which allows for variable tone control compared to internal driver alternatives.

Part Context

This part belongs to the AST series of surface-mount buzzers from Mallory Sonalert. It is designed for automated assembly processes due to its SMD configuration. The product provides a reliable acoustic signaling solution for modern electronic devices where board space is limited.

Replacement Considerations

AST0927ME-05T&R is a confirmed substitute part number representing the same functional unit in different packaging configurations.
