10 pcs : SMT-0440-T-2-R - Speakers & Transducers 3 VP-P 90 MA SMT TRANSDUCER

SMT-0440 Surface-Mount Transducers PUI Audio SMT-0440 Surface-Mount Transducers are 20% smaller than the SMT-0540 transducers, adding sound to even smaller devices. Both the side-firing SMT-0440-S-R and the top-firing SMT-0440-T-R feature overall dimensions of 4mm wide x 4mm deep x 2mm high to accommodate crowded PCBs. PUI Audio SMT-0440 Surface-Mount Transducers are built to be powered by a 2V0-p to 4V0-p square wave, and each device is capable of producing a 70dB, 4kHz tone (measured at 10cm) while consuming no more than 90mA.
