Press Release Summary:

June 27, 2014 - Sound pressure level output, measured 10 cm from PKMCS0909E4000-R1, is >65 dB when driven with ±1.5 V, 4 kHz square wave. Max peak-to-peak voltage is ±12.5 V, and power consumption is 0.6 mW typ. Latter helps preserve battery life in consumer electronic devices. Measuring 9 x 9 x 1.7 mm and weighing 160 mg, sounder does not use any magnets or coils to create sound. This eliminates generation of electrical noise and minimizes impact on surrounding circuitry.

Ultra Compact Light and Low Power SMD Piezoelectric Sounder Suits Portable Health Care Devices

Press release date: June 1, 2014

Hoofddorp, Netherlands: Murata today announced they have commenced mass production of, what they believe, to be 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 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.

Typical applications for the PKMCS0909E4000-R1 include blood glucose meters, personal thermometers, camera strobe flash and Bluetooth dongles.
