Murata – Ultra compact light and low power SMD piezoelectric sounder PKMCS0909E4000
Occupying significantly less surface area, and with a combined weight and area reduction of 44% compared to previous Murata products, the PKMCS0909E4000-R1 measures just 9 x 9 x 1.7 mm and weighs only 160 mg.
Sound pressure level output, measured 10 cm from sounder, is better than 65 dB when driven with a +/- 1.5 V 4kHz square wave. Maximum peak-to-peak voltage is +/- 12.5 V. Power consumption is typically 0.6 mW, which helps preserve battery life in power budget constrained consumer electronic devices. Since the sounder does not use any magnets or coils to create sound it doesn’t generate any electrical noise and therefore has minimum impact on surrounding circuitry.
