Murata | PKLCS1212E4001-R1

Murata Electronics’ piezoelectric sound components (piezo alarms) are designed for applications requiring a highly reliable acoustic alarm or audible tone signal. Their reliability extends from the fact that they are solid state construction so they have very few moving parts.

These devices can produce either a single or multi-frequency output depending upon operating requirements. The tone is distinct due to the absence of harmonics, and gives an extremely clear, penetrating sound.

With high acoustic output versus low input power requirements, Murata sound components are ideal for a wide variety of applications, especially products powered by battery.

The PKLCS series are SMD piezoelectric sounders that suitthe  thin, high-density design of electronic equipment where biard space is limited.

The PKLCS1212E4001-R1 has dimensions of  12 mm L x 12 mm W x 3 mm. In spite of a small package, the PKLCS1212E4001-R1 it has a very respectable sound level of  75 dB min at 3Vp-p with 4kHz square wave at  a distance of 10cm.

Note: The “-R1” on the end of the part number PKLCS1212E4001-R1 denotes plastic tape and reel packaging on a 330 mm reel.
