SMT-0440 Series 4 x 4 x 2 mm Surface-Mount Transducers

PUI Audio brings devices to life with the SMT-0440 series transducers

Image of PUI Audio SMT-0440 Series TransducersPUI Audio pushes the envelope of audio transducer design by shaving the size of their already small SMT-0540 transducers down 20% with their new SMT-0440 series surface-mount transducers, adding sound to even smaller devices than ever before. Both the side-firing SMT-0440-S-R and the top-firing SMT-0440-T-R feature overall dimensions of 4 mm wide, by 4 mm deep by 2 mm high to accommodate even the tightest, most crowded PCBs. Built to be powered by a 2 to 4 V0-p square wave, each device is capable of producing a 70 dB, 4 kHz tone (measured at 10 cm) while consuming no more than 90 mA.
