Overview
The AST0932ME-05Q is a surface-mount piezoelectric transducer manufactured by Mallory Sonalert Products Inc. It operates at a rated voltage of 5 VDC and draws 80 mA. The device produces an externally driven magnetic signal with a frequency of 3.2 kHz and a sound pressure level of 85 dB measured at 10 cm. Its compact package dimensions are 9 mm x 9 mm with a maximum height of 3.2 mm, utilizing solder pads for termination.
Feature Summary
- Externally driven magnetic transducer technology
- Surface mount solder pad termination
- Compact low-profile physical design
Applications
- Industrial control panel alarms
- Medical equipment audio alerts
- Consumer electronics status indicators
Procurement Notes
Verify the specific suffix 'Q' against the manufacturer's current datasheet to confirm compliance with RoHS3 regulations and REACH standards. Ensure the ordering documentation explicitly references the externally driven magnetic type rather than internally driven variants within the same series. Confirm that the 5V rating aligns with the target circuit supply voltage before procurement.
Selection Notes
Select this component when a low-voltage, high-intensity audible alert is required in space-constrained designs. The 85 dB output provides clear signaling in moderate noise environments. Consider the 80 mA current draw during power budget calculations. The surface mount format facilitates automated assembly processes for high-volume manufacturing applications.
Part Context
This part belongs to the AST series of piezoelectric transducers from Mallory Sonalert. The series offers various voltage and frequency options. The AST0932ME-05Q specifically targets 5V systems requiring a 3.2 kHz tone. It serves as a visual and audible warning solution within the broader Sonalert product portfolio.
Replacement Considerations
Consult the official Mallory Sonalert cross-reference sheet for obsolete Murata buzzers. Verify pinout compatibility and acoustic performance equivalence before substituting with other surface-mount transducers.
