AST100Q

Overview

The AST100Q is a piezoelectric transducer designed for audio indication applications. It operates at a rated voltage of 5 VDC with a current rating of 1.5 mA. The device produces a sound pressure level of 80 dBA at a frequency of 4 kHz. Physical dimensions are 17 mm in length, 17 mm in width, and 5 mm in height. Termination is achieved via gullwing leads.

Feature Summary

• Piezoelectric transduction mechanism
• Gullwing lead termination style
• Compact rectangular form factor

Applications

• Audio indicators
• Sound pressure level monitoring
• Electrical equipment status alerts

Procurement Notes

Verify the specific datasheet version to confirm RoHS compliance details and exact physical tolerances. Ensure the operating voltage matches the 5 VDC rating to prevent damage. Confirm that the gullwing lead termination is compatible with the intended PCB footprint and soldering process.

Selection Notes

Select this component when a low-voltage, low-current audible indicator is required. The 5 VDC rating suits logic-level circuits. The 80 dBA output provides moderate audibility. Consider the 17x17 mm footprint for space-constrained designs requiring through-hole or surface-mount integration via gullwing leads.

Part Context

This part belongs to the Mallory Sonalert transducer portfolio, categorized under audio indicators and alerts. It serves as a standalone acoustic element for signaling purposes within electronic assemblies, distinct from integrated buzzers or speakers.
