Mallory — AST1341MCTRQ Buzzers

The AST1341MCTRQ is a sound output transducer from Mallory which enables designers to include a loud buzzer in a completely surface-mount circuit board assembly. This eliminates the time and labor involved in assembling a through-hole sonic component to the board.

The AST1341MCTRQ is one of a broad family of Mallory surface-mount buzzers, including both piezoelectric and electromagnetic devices.

Requiring an input current of just 8 mA, the AST1341MCTRQ transducers can produce up to 90 dB of sound, making the devices suitable for use in a variety of applications, including timers, key pads, monitors, meters and measurement equipment.

The transducers have two terminals or wires which are connected to the piezoelectric element. By applying a sine or square wave to the device at the appropriate drive frequency on the specification sheet, an audible sound at that frequency will be produced. The higher the peak-to-peak voltage applied up to the rated maximum, the higher the sound level.

Available in a variety of sizes, the surface-mount buzzers from Mallory can be purchased in cut-tape or tape-and-reel packages.
