Procurement Notes
Verify the specific suffix against official Murata documentation to confirm exact acoustic and electrical characteristics. Ensure the selected variant matches the required driving circuitry and mounting style for the target application. Cross-reference datasheets for precise dimensional tolerances and environmental ratings before finalizing procurement specifications.
Selection Notes
Select this component for applications requiring low power consumption and high reliability without internal driver circuits. The external drive requirement allows for flexible signal integration. Verify that the 2kHz continuous tone meets the auditory notification needs of the end product within the specified temperature range.
Part Context
This part belongs to the Murata PKM series of piezoelectric buzzers. These components are designed as standalone transducers, distinct from self-oscillating types. They provide a cost-effective solution for audio indication in compact electronic devices where space and power efficiency are critical constraints.
Replacement Considerations
Direct substitutes include other PKM22 variants such as PKM22EPPH4001-B0 or PKM22EPTH2001-B0 equivalents. Verify compatibility regarding mounting style (through-hole vs surface mount) and operating frequency when selecting alternative part numbers.
