The AST7525MATRQ is an electromagnetic buzzer from the Mallory Sonalert AST series, designed for surface-mount technology (SMD/SMT) applications. It operates at a rated voltage of 3.6 V with a current rating of 100 mA. The device produces a sound pressure level of 85 dB at a frequency of 2.7 kHz. Its compact dimensions are 7.5 mm x 7.5 mm x 2.5 mm, utilizing solder pad termination. It is supplied in a reel package.
Verify the specific suffix MATRQ to confirm the reel packaging format and electromagnetic type. Ensure the operating circuit supports the 3.6 V DC requirement and 100 mA current draw. Confirm that the PCB footprint matches the 7.5 mm x 7.5 mm solder pad dimensions. Check RoHS compliance documentation if required by your manufacturing standards.
Select this component when a low-profile, surface-mount electromagnetic buzzer is required. It is appropriate for designs needing a 2.7 kHz tone with 85 dB output. Consider the 3.6 V rating against available supply rails. Compare against piezoelectric alternatives if lower current consumption is critical, as this model draws 100 mA.
This part belongs to the Mallory Sonalert AST series of audio indicators. The series includes various electromagnetic and piezoelectric options in SMD packages. The AST7525MATRQ specifically represents the electromagnetic variant within this lineup, distinguished by its magnetic driver mechanism rather than a piezoelectric ceramic element.
No, it is an external drive electromagnetic transducer requiring an external oscillator circuit to generate the 2.7 kHz signal.
It uses a surface-mount (SMD/SMT) style with solder pads for attachment to the printed circuit board.
