Overview
The PKLCS1212E2400-R1 is a surface-mount piezoelectric sounder manufactured by Murata Electronics. It features a low-profile SMD package measuring 12x12mm with a height of 3mm. The device operates at a resonant frequency of 2.4 kHz and delivers a typical sound pressure level of 80 dB, with a minimum of 75 dB. Designed for external driving circuits, it supports a maximum voltage range of 25V.
Feature Summary
- Low profile surface mount package suitable for space-constrained designs
- Fully reflow solder compatible for automated assembly processes
- Piezoelectric construction providing high acoustic output
Applications
- Portable electronic devices requiring audible alerts
- Industrial equipment signaling systems
- Automotive market applications
Procurement Notes
Verify the specific suffix against official Murata documentation to confirm the exact acoustic performance tier and material composition. Ensure the ordering part number matches the required 2.4 kHz frequency specification. Confirm that the component meets all necessary environmental and reliability standards for the intended deployment environment before finalizing procurement.
Selection Notes
Select this component when a compact, low-profile audible indicator is required for portable or industrial use. The 2.4 kHz frequency offers a distinct tone compared to standard 2 kHz variants. Consider the 80 dB SPL rating for environments requiring clear auditory feedback without excessive power consumption.
Part Context
This model belongs to the PKLCS family of piezoelectric sounders from Murata Electronics North America. The series was expanded to include 2.4 kHz variants specifically targeting the portable, industrial, and automotive markets. These components are designed to minimize leaded component usage while maintaining low profile requirements.
Replacement Considerations
The PKLCS1212E24A1-R1 serves as an alternative within the same family, designated for automotive and industrial versions. Verify if the A1 suffix variant meets the specific environmental requirements of the application.
