PKLCS1212E24A0-R1

Overview

The PKLCS1212E24A0-R1 is a surface-mount piezoelectric sounder from the Murata PKLCS family, designed for portable, industrial, and automotive applications. It features a low-profile SMD package measuring 12x12mm with a height of 3mm. The device operates at a frequency of 2.4 kHz and utilizes an external drive method. It offers a 5-dB increase in sound pressure level compared to the 2 kHz variant within the same series. The component is fully compatible with reflow soldering processes.

Feature Summary

• Low profile surface mount package suitable for space-constrained designs
• Fully reflow solder compatible for automated assembly
• Enhanced sound pressure level relative to standard 2 kHz models

Applications

• Portable electronic devices
• Industrial equipment signaling
• Automotive systems

Procurement Notes

Verify the exact suffix against official Murata documentation to confirm specific performance grades or environmental ratings. Ensure the ordering part number matches the required frequency and voltage specifications. Confirm availability status directly with authorized distributors as supply levels may vary.

Selection Notes

Select this model when a higher acoustic output than the standard 2 kHz version is required without increasing the physical footprint. Consider the external drive requirement for circuit design. Verify that the operating temperature range meets the specific application environment requirements.

Part Context

This component belongs to the PKLCS family of piezoelectric sounders. The family targets markets requiring miniaturization and lead-free manufacturing compliance. The 12x12mm form factor allows for integration into compact assemblies where traditional through-hole components are unsuitable.
