Murata launches ultra low-profile surface mount 2.4 kHz piezo sounders

The new PKLCS sounders’ thin 3 mm profile make them suitable for use in miniaturized portable electronics. Further, the SMD package enables more efficient manufacturing since the parts can be mounted using pick and place equipment. Other benefits include the ability to survive reflow soldering with no impact to performance and a low frequency operation (2.4kHz) with improved loudness verse existing 2kHz product. The small increase in operational frequency 2.0kHz to 2.4kHz permits significant gains in loudness.
