AST1750MATRQ

Overview

The AST1750MATRQ is a surface-mount audio transducer manufactured by Mallory Sonalert Products Inc. It operates at a rated voltage of 5V and draws a current of 100 mA. The device produces a single-tone signal with a peak-peak frequency of 4 kHz. It achieves a sound pressure level of 80 dB. The physical dimensions are 17 mm in length, 17 mm in width, and 5 mm in height. It utilizes solder pad termination for board mounting.

Feature Summary

• Surface-mount technology design for automated assembly
• Single-tone acoustic output generation
• Compact square form factor suitable for dense PCB layouts

Applications

• Industrial control panel indicators
• Consumer electronic device alerts
• Medical equipment status signaling

Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required packaging formats such as cut tape or reel quantities. Confirm that the voltage rating aligns with the target circuit design to prevent damage. Check RoHS compliance documentation for regulatory adherence in restricted substance environments. Ensure the operating temperature range meets the environmental conditions of the final application.

Selection Notes

Select this component when a compact, surface-mount buzzer is required for high-volume production. Compare against through-hole alternatives if mechanical robustness during handling is critical. Evaluate the 80 dB SPL requirement against ambient noise levels to ensure audibility. Consider the 4 kHz frequency for optimal human hearing sensitivity in alert scenarios.

Part Context

This part belongs to the AST series of surface-mount transducers from Mallory Sonalert. The series focuses on providing reliable audio indication solutions in small footprints. It complements the company's broader portfolio of panel alarms and stack lights by offering integrated PCB-mounted options for modern electronics.

Replacement Considerations

Direct substitutes include other SMD buzzers with similar 4 kHz frequency and 80 dB SPL ratings. Verify pinout compatibility and thermal characteristics before swapping. Consult manufacturer cross-reference lists for exact functional equivalents.
