Overview
The PKLCS1212E2000-R1 is a surface-mount piezoelectric sounder manufactured by Murata Electronics. It features a 12x12mm footprint with a low profile height of 3mm. The device operates at a resonant frequency of 2kHz and delivers a sound pressure level of 76dB. Designed for external driving, it supports a maximum voltage of 25V and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Low profile surface mount package suitable for space-constrained designs
- Piezoelectric construction for reliable acoustic output
- Fully reflow solder compatible for automated assembly
Applications
- Portable electronic devices requiring compact audio indicators
- Industrial equipment status signaling
- Automotive interior alert systems
Procurement Notes
Verify the specific suffix designation against official Murata documentation to confirm exact electrical tolerances and material composition. Ensure that the selected variant matches the required operating temperature range and acoustic performance specifications for the target application environment before finalizing procurement orders.
Selection Notes
Select this component when a low-profile, externally driven piezoelectric buzzer is required for portable or industrial applications. Consider the 2kHz frequency and 76dB SPL for appropriate audible alerting needs. Verify compatibility with standard SMT reflow processes and ensure the 25V maximum rating aligns with the system's drive circuit capabilities.
Part Context
This part belongs to the PKLCS family of piezoelectric sounders from Murata Electronics. The series is characterized by its small 12x12mm form factor and thin 3mm profile, designed to minimize leaded component usage in modern electronics manufacturing.
Replacement Considerations
The PKLCS1212E20A0-R1 is listed as a similar product within the same manufacturer portfolio. Verify functional equivalence regarding acoustic output and mounting dimensions before substitution.
