PKLCS1212E40A1-R1 Description

Short technical summary and product information.

The PKLCS1212E40A1-R1 is a piezoelectric sounder manufactured by Murata. It operates at a resonant frequency of 4kHz with a single tone operating mode. The driver type is externally driven, requiring a zero-peak signal input. The rated voltage is 1.5V, with a maximum voltage of 25V. It produces a sound pressure level of 75dB at 10cm when driven at 1.5V.

 

This sounder features a side port location and is designed for surface mount assembly with solder pad termination. The package measures 12.00mm x 12.00mm with a height of 3.00mm. It operates over a temperature range of -40°C to 85°C. The component is RoHS3 compliant and has an MSL rating of 1 (unlimited).

 

Typical applications include alarm systems, medical devices, and consumer electronics requiring a compact audible indicator. The packaging is plastic taping for automated pick-and-place.
