Overview
The ASI09N27M-05Q is a surface-mount electromagnetic buzzer manufactured by Mallory Sonalert Products Inc. It operates at a rated voltage of 5V DC and produces a continuous single-tone sound at a frequency of 2.7 kHz. The device delivers an acoustic output of 80 dB measured at 3V and 10 cm distance. Its compact footprint measures 9.5 mm by 9.5 mm, designed for direct integration onto printed circuit boards via surface mount technology.
Feature Summary
- Electromagnetic transducer mechanism for audible signaling
- Surface-mount package design for automated PCB assembly
- Internal driving circuitry for direct logic interface
Applications
- Consumer electronics status indication
- Portable device audio alerts
- Compact industrial control panel indicators
Procurement Notes
Verify the specific suffix 'Q' against the manufacturer's current datasheet to confirm compliance with RoHS directives and halogen-free requirements. Ensure the ordering quantity matches the standard factory packaging specifications provided in the official documentation to avoid handling discrepancies during assembly.
Selection Notes
Select this component when a low-profile, surface-mount solution is required for 5V systems. The electromagnetic type offers distinct acoustic characteristics compared to piezoelectric alternatives. Confirm that the 80 dB SPL at 3V meets the environmental noise requirements of the target application space.
Part Context
This part belongs to the ASI series of Mallory Sonalert products, which specializes in miniature surface-mount audible indicators. The series provides various voltage and frequency options tailored for space-constrained electronic designs requiring reliable audio feedback without through-hole mounting constraints.
Replacement Considerations
Cross-reference with Mallory's official cross-reference sheet for obsolete Murata buzzers. Verify pinout compatibility and acoustic performance equivalence before substituting with other SMD electromagnetic buzzers from different manufacturers.
