The CMT-1102-SMT-TR is an externally driven piezo buzzer transducer designed for surface-mount applications. It operates with a rated frequency of 4,100 Hz and produces a minimum sound pressure level of 73 dB at 10 cm when driven with a 5 Vp-p square wave. This low-profile transducer has a maximum operating voltage of 25 Vp-p, consumes up to 4.5 mA of current, and is housed in a compact 11 x 9 x 1.7 mm package. With an operating temperature range of -40 to 80°C, it is well-suited for automated assembly in various electronic requiring audible alerts.
