AST0727MW-3.6AQ

Overview

The AST0727MW-3.6AQ is a surface-mount magnetic buzzer manufactured by Mallory Sonalert Products Inc., designed for compact electronic assemblies. It operates on a DC input voltage range of 2.5 to 4.5 volts, with a nominal rating of 3.6 volts. The device generates an acoustic signal at a frequency of 2.7 kHz, achieving a sound pressure level of 85 dB when measured at a distance of 10 cm from the source. Electrical consumption is specified at 100 mA during operation. The component utilizes externally driven circuitry and features solder pad termination for direct PCB mounting.

Feature Summary

• Surface-mount construction with solder pad termination for automated assembly
• Externally driven magnetic transducer technology
• Compact form factor suitable for space-constrained designs

Applications

• Embedded system status indication
• Portable consumer electronics alerts
• Medical device signaling

Procurement Notes

Verify that the specific ordering suffix matches the required acoustic output and electrical characteristics. Confirm that the surface-mount footprint aligns with the target PCB design guidelines. Ensure the operating voltage range of the host system remains within the 2.5 to 4.5 volt specification to prevent damage or performance degradation. Check for RoHS compliance requirements if applicable to the final product regulations.

Selection Notes

Select this component when a low-profile, surface-mount solution is required for audible signaling in battery-operated devices. The external drive requirement necessitates a microcontroller or driver circuit capable of sourcing 100 mA. Consider the 85 dB SPL for audibility needs in typical environments. Evaluate thermal management capabilities if the device will operate continuously near maximum current limits.
