AST1341MCTRQ

Overview

The AST1341MCTRQ is a surface-mount piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It operates on a 5V DC supply with a current consumption of 8mA. The device generates an acoustic output of 90dB at a distance of 10cm, measured at a frequency of 4.1kHz. Designed for external driving circuits, it utilizes solder pads for PCB mounting in a compact 13x13mm package.

Feature Summary

• Surface-mount construction for automated assembly
• Piezoelectric transducer technology
• Externally driven circuit design

Applications

• Medical equipment audio indicators
• Industrial control panel alarms
• Consumer electronics status alerts

Procurement Notes

Verify the specific suffix 'CTRQ' to confirm tape and reel packaging requirements against your manufacturing line specifications. Ensure the external drive circuitry matches the 5V DC input and 8mA load characteristics defined in the official datasheet to maintain performance integrity.

Selection Notes

Select this component when a low-profile surface-mount solution is required for 5V systems. The externally driven architecture allows for flexible waveform generation compared to internal driver variants. Confirm that the 90dB SPL meets the auditory requirements of the target enclosure environment.

Part Context

This part belongs to the AST series of miniature piezo buzzers from Mallory Sonalert Products Inc. The series is engineered for space-constrained applications requiring reliable audio signaling. The manufacturer specializes in industrial and medical warning devices with extensive certification histories.

Replacement Considerations

Direct substitutes must match the 13x13mm footprint, 5V operating voltage, and surface-mount termination type. Verify pin compatibility and acoustic output levels before integration.
