Ultra-Compact, Light-Weight, and Low-Power SMD Pie

Murata now is offering the smallest and lightest surface-mount piezoelectric sounder available. 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 mm x 9 mm 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 4 kHz 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 does not generate any electrical noise and therefore, has minimum impact on surrounding circuitry. Typical applications for the PKMCS0909E4000-R1 include blood glucose meters, personal thermometers, camera strobe flash, Bluetooth dongles, or any other small, portable equipment application where an audible alert tone is required.
