Murata's PKL family of SMD piezoelectric sounders are provide in a 12mm x 12mm package, with a seated height of only 3.0mm, maximum. These devices employ a two-element piezo diaphragm for reproduction of a wide range of audio tones. Typical Sound Pressure Level (SPL) is 70dB @ 10 cm for a 2.0kHz, 3-Vpp, square wave signal, and 75dB @ 10 cm for a 4.0kHz, 3-Vpp square wave signal. An automotive grade version is offered for operation over the -40/+85°C temperature range. All products are RoHS compliant.
