ASI09N27MFD-03Q

Overview

The ASI09N27MFD-03Q is a through-hole magnetic buzzer manufactured by Mallory Sonalert Products Inc. It operates on a DC voltage range of 2 to 5V with a current consumption of 30mA. The device produces a continuous tone at a frequency of 2.7kHz, delivering a sound pressure level of 80dB at 3V measured from a distance of 10cm. It features solder pad termination for PCB mounting and is designed for use as an audio indicator in electronic circuits.

Feature Summary

• Internally driven magnetic buzzer design
• Continuous tone operation mode
• Through-hole solder pad termination

Applications

• Electronic equipment status indicators
• Audio alert systems
• Control panel signaling

Procurement Notes

Verify the specific suffix Q against the manufacturer's official datasheet to confirm exact electrical tolerances and terminal configurations. Ensure the input voltage remains within the 2-5V DC range to prevent damage. Confirm RoHS compliance status via the latest certification documents before integration into regulated assemblies.

Selection Notes

Select this component when a low-voltage, high-current magnetic buzzer is required for through-hole assembly. Compare against piezoelectric alternatives if lower power consumption is critical, as this model draws 30mA. Ensure the enclosure allows for adequate sound projection given the 80dB output level.

Part Context

This part belongs to the ASI series of board-mount buzzers from Mallory Sonalert. The series includes various electromagnetic and piezoelectric options for different voltage and mounting requirements. The ASI09N27MFD-03Q specifically addresses applications needing robust acoustic output at low supply voltages using standard PCB mounting techniques.

Replacement Considerations

Cross-reference with ASI09N27MFD-03TRQ for reel-packaged versions. Verify pin compatibility and acoustic performance against other ASI series models before substitution.
