Overview
The AST0540MW-3.6TRQ is a surface-mount electromagnetic transducer from the Mallory Sonalert AST series, designed for board-level audio indication. It operates at a rated voltage of 3.6 VDC with a typical current draw of 100 mA. The device features a resonant frequency of 3900 ± 500 Hz and delivers a sound pressure level of approximately 85 dB. Its compact SMD/SMT package measures 7.5 mm x 7.5 mm x 2.5 mm, utilizing solder pad termination for automated assembly.
Feature Summary
- Electromagnetic transduction mechanism for reliable audible signaling
- Surface-mount technology (SMT) compatible design for high-volume manufacturing
- Integrated circuitry for direct drive operation without external components
Applications
- Medical device alarm systems
- Industrial control panel indicators
- Consumer electronics status alerts
Procurement Notes
Verify the specific ordering suffix to confirm the reel quantity and tape specifications required for your pick-and-place equipment. Ensure the voltage rating aligns with your system's power supply rails. Confirm RoHS compliance status if environmental regulations apply to your final product assembly.
Selection Notes
Select this component when a low-profile, board-mounted solution is required instead of through-hole or panel-mount alternatives. Consider the 85 dB output sufficient for your acoustic environment. Verify that the 3.6 VDC operating voltage matches your available logic levels or power distribution network.
Part Context
This part belongs to the AST series of surface-mount transducers, which offers various voltage and frequency options within a standardized footprint. The series is engineered for integration into modern PCB layouts where space constraints and automated assembly processes are critical factors in the design phase.
Replacement Considerations
Cross-reference with other AST series variants such as AST0540MW-3.6Q for cut-tape availability or different reel configurations. Ensure mechanical dimensions and pinout compatibility before substituting with generic electromagnetic buzzers.
