AST605Q

Overview

The AST605Q is a piezoelectric buzzer from the Mallory Sonalert series, designed for board-mount applications. It operates on a 5V DC supply with a rated voltage range of 4 to 7V peak-to-peak. The device generates a single-tone continuous signal at a frequency of 2.4 kHz. Key electrical parameters include a current draw of 12.6 mA and an acoustic output level of 85 dB. The unit features a grey housing and utilizes through-hole PC pin termination for secure circuit integration.

Feature Summary

• Generates a continuous single-tone audible alert signal
• Integrates directly onto printed circuit boards via through-hole pins
• Operates within a standard low-voltage DC power range

Applications

• Electronic equipment status indication
• Alarm systems requiring compact audio alerts
• Consumer appliance control panels

Procurement Notes

Verify that the target application circuit provides a stable 5V DC supply compatible with the specified 4-7V peak-to-peak input range. Confirm that the PCB layout accommodates the specific through-hole pin spacing and physical dimensions of the 12.6x12.6mm package to ensure proper mechanical fit and electrical connection during assembly.

Selection Notes

Select this component when a compact, board-mounted solution is required for simple tone generation. The AST605Q is suitable for designs prioritizing low profile and direct integration over external mounting options. Consider the 85 dB output level against ambient noise requirements and verify that the 2.4 kHz frequency aligns with the intended auditory signaling needs of the end product.

Part Context

This part belongs to the Mallory Sonalert family of audio indicators, known for reliable piezoelectric technology. The AST605Q represents a standard board-mount variant within this lineup, offering a balance of acoustic performance and small form factor. It serves as a fundamental component for basic alerting functions in various electronic assemblies where dedicated microcontroller-driven speakers are unnecessary.
