MURATA AMERICAS: Piezoelectric Buzzer

This company has expanded its surface mount piezoelectric buzzer line with PKMCS0909E4000-R1, reportedly the smallest surface-mount buzzer available on the market. Measuring 9 x 9 mm, the piezoelectric solution can fully withstand reflow soldering without the slightest degradation in performance. It can also deliver a low profile of 1.9 mm, while maintaining a loudness of 65 dB minimum at 4 kHz (with a battery-friendly drive voltage of +/- 1.5 Vo-p). Louder sound output is possible with higher drive voltage. 

“Murata was the first-to-market with a true surface-mount piezoelectric buzzer, and we continue to push technological and materials advancements to yield another industry first,” said Peter Tiller, Device Product Group general manager. “For years, offered products have struggled to maintain peak performance after reflow soldering. Murata’s surface-mount buzzer product line unquestionably resolves that for design engineers while offering this next step in the miniaturization of piezoelectric buzzers. We achieve this through our piezoelectric ceramics’ unsurpassed stability, performance, and reliability.
