ASI301TRQ

Overview

The Mallory Sonalert Products Inc. ASI301TRQ is a surface-mount magnetic buzzer designed for compact electronic assemblies. It operates within a DC voltage range of 4 to 7 volts and generates an acoustic signal at a frequency of 2.3 kHz. The component utilizes a printed circuit board (PCB) mounting style, facilitating automated assembly processes. Its physical dimensions are specified as 12.6 mm by 12.6 mm, allowing integration into space-constrained designs. The device functions as a constant tone indicator, providing reliable audio feedback for system status monitoring.

Feature Summary

• Surface-mount technology enables direct PCB integration without through-hole requirements.
• Internal driver circuitry simplifies interface connections with standard logic levels.
• Compact rectangular footprint supports high-density layout configurations.

Applications

• Consumer electronics status indication
• Industrial control panel signaling
• Medical device audio alerts

Procurement Notes

Verify the specific suffix TRQ confirms tape-and-reel packaging when sourcing from distributors. Confirm the operating voltage range aligns with the target power supply rails. Ensure the surface-mount pad layout matches the manufacturer's recommended land pattern for reliable soldering. Check RoHS compliance documentation if required by project specifications.

Selection Notes

Select this component when a low-profile, surface-mount solution is required for audible signaling. Compare against piezoelectric alternatives if higher sound pressure levels or different waveform capabilities are necessary. Evaluate thermal constraints during reflow soldering due to the small form factor. Consider current consumption limits within the host system design.

Part Context

This part belongs to the Mallory Sonalert magnetic buzzer family, which focuses on compact, cost-effective audio indicators. Unlike piezoelectric series such as SCE or SC, these units rely on electromagnetic coils for sound generation. The TRQ suffix typically denotes reel packaging for automated manufacturing, distinguishing it from bulk or single-unit variants.

Replacement Considerations

Direct substitutes require matching the 12.6x12.6mm footprint and 4-7VDC operating range. Verify that alternative magnetic buzzers support similar 2.3kHz frequencies. Ensure the replacement component maintains compatible pinout configurations for seamless PCB integration without redesign.

FAQ
