AST0925ME-05TRQ

Overview

The AST0925ME-05TRQ is a surface-mount magnetic transducer manufactured by Mallory Sonalert Products Inc. It operates at a nominal voltage of 5V with a current consumption of 80mA. The device produces a sound pressure level of 85dB measured at 10cm and functions at a frequency of 2.5kHz. Designed for externally driven applications, it features solder pad termination and measures 8.7 x 8.7 x 4 mm.

Feature Summary

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

Applications

• Industrial control panels
• Medical equipment alarms
• Consumer electronics indicators

Procurement Notes

Verify the specific suffix TRQ to confirm tape-and-reel packaging configuration. Ensure the external drive circuitry matches the 80mA current requirement. Confirm that the 5V nominal voltage aligns with the system power supply. Check RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a compact, surface-mount solution is required for audible signaling. The externally driven nature allows for flexible waveform generation. Consider the 85dB SPL for environments requiring clear audio alerts. Verify mechanical clearance for the 4mm height constraint.

Part Context

This part belongs to the AST series of magnetic transducers from Mallory Sonalert. These components are designed for integration into various warning systems where space is limited. The series offers options for different voltages and mounting styles to suit diverse electronic designs.

Replacement Considerations

Consult Mallory Sonalert cross-reference documentation for direct substitutes. Verify pinout compatibility and acoustic performance equivalence before substitution.
