AST0927MW-03TRQ

Overview

The AST0927MW-03TRQ is a surface-mount magnetic transducer manufactured by Mallory Sonalert Products Inc. It operates on an externally driven input with a voltage range of 2 to 5 VAC. The device produces a single-tone peak-peak signal at a frequency of 2.7 kHz. It delivers a sound pressure level of 90 dB measured at 3 V and 10 cm distance. Electrical consumption is specified as 90 mA. The component utilizes side port location for acoustic output. Physical dimensions are 9.0 mm in length, 10.5 mm in width, and 2.5 mm in height. Termination is achieved via solder pads suitable for tape-and-reel packaging.

Feature Summary

• Surface-mount magnetic transducer design
• Externally driven operation mode
• Single-tone peak-peak signal generation

Applications

• Electronic audio indicators
• Alarm systems
• Buzzer applications

Procurement Notes

Verify the specific ordering suffix and package configuration against the manufacturer's current documentation before procurement. Confirm that the external drive circuitry matches the required 2 to 5 VAC operating range and 90 mA current specification. Ensure the surface-mount footprint aligns with the 9.0 x 10.5 mm dimensions and solder pad layout. Check for any non-cancelable or non-returnable status associated with this specific part number variant.

Selection Notes

Select this component when a surface-mount magnetic transducer is required for space-constrained designs. Choose this model if the application demands an externally driven solution rather than an internally driven buzzer. Consider the 90 dB SPL rating and 2.7 kHz frequency for audible alert requirements. Verify compatibility with tape-and-reel assembly processes due to the SMT termination style.
