Overview
The AST7525MAQ is an electromagnetic transducer from the Mallory Sonalert AST series, designed for surface-mount technology (SMD/SMT) applications. It operates at a rated voltage of 3.6 V and draws a current of 100 mA. The device produces a sound pressure level of 85 dB at a frequency of 2.7 kHz. Its physical dimensions are 7.5 mm in length, 7.5 mm in width, and 2.5 mm in height, with a unit weight of 2 g. The component utilizes solder pad termination and is supplied in cut tape packaging.
Feature Summary
- Electromagnetic transducer type suitable for board-level audio indication
- Surface-mount design with solder pad termination for automated assembly
- Compact form factor optimized for space-constrained PCB layouts
Applications
- General electronic equipment status indicators
- Consumer appliance audible alerts
- Industrial control panel signaling
Procurement Notes
Verify the specific suffix MAQ to confirm cut tape packaging configuration against the required reel specifications for your manufacturing line. Ensure the 3.6 V rating aligns with the target circuit supply voltage to prevent under-driving or excessive current draw. Confirm RoHS compliance status through the official datasheet before finalizing procurement orders.
Selection Notes
Select this model when a low-profile SMT solution is required for 3.6 V systems. The 2.7 kHz frequency provides a distinct audible tone suitable for general alarms. Consider the 100 mA current consumption during power budget calculations. Compare against other AST series variants if different voltage ratings or sound pressure levels are necessary for the application.
Part Context
This component belongs to the Mallory Sonalert AST series of surface-mount transducers. The series offers various voltage and frequency options within a standardized footprint. The AST7525MAQ specifically addresses needs for compact, low-voltage electromagnetic audio signaling in modern electronics where board space is limited.
Replacement Considerations
AST7525MATRQ serves as a substitute option, differing primarily in packaging format as it is supplied on a reel rather than in cut tape.
