Overview
The PKM22EPH2002 is a piezoelectric ringer manufactured by Murata Electronics, designed for through-hole mounting. It operates at a fundamental frequency of 2 kHz with a rated voltage of 3V peak-to-peak and a maximum voltage rating of 25V. The device features PC pins for termination and delivers a sound pressure level of 75 dBA. It functions as an externally driven transducer suitable for continuous operation modes within a temperature range of -20°C to 70°C.
Feature Summary
- Externally driven piezoelectric technology for audio indication
- Through-hole mounting with PC pin termination
- Continuous operating mode capability
Applications
- General purpose alarm systems
- Audio indicators in consumer electronics
- Sounder applications requiring 2kHz tone generation
Procurement Notes
Verify the specific model suffix against official documentation to confirm electrical ratings, as variations exist within the series. Confirm that the required operating environment falls within the specified -20°C to 70°C temperature range. Ensure the driving circuitry can supply the necessary peak-to-peak voltage without exceeding the 25V maximum rating. Check for any discontinuation notices or lifecycle status updates from the manufacturer prior to finalizing procurement plans.
Selection Notes
Select this component when a 2kHz audible alert is required for through-hole PCB designs. It is appropriate for applications needing a 75 dBA sound output driven by external circuitry. Consider the physical dimensions and lead configuration during layout planning. Verify compatibility with the target system's voltage levels and thermal constraints before integration into the design.
Part Context
This component belongs to the PK series of Piezoringer devices from Murata Electronics. These are standard piezoelectric buzzers intended for board-level audio signaling. The series offers various frequencies and drive types, with this specific model providing a 2kHz output via through-hole pins.
Replacement Considerations
Consult official Murata documentation for direct cross-references. Alternative models may require verification of frequency tolerance, sound pressure level, and voltage ratings to ensure functional equivalence.
