Overview
The PKM22EPPH4012-B0 is a piezoelectric buzzer from the Murata PIEZORINGER series, designed for through-hole mounting. It features a 22 mm diameter and 12 mm height with solder pin termination. The device operates at a rated voltage of 15 V DC and produces a single tone at 4 kHz. It delivers a sound pressure level of 92 dB. Packaged in bulk quantities of 750 units, this component is classified as an external drive audio indicator.
Feature Summary
- External drive piezoelectric technology for direct circuit integration
- Through-hole installation with solder pin termination
- Single continuous tone generation capability
Applications
- General purpose audio alerts
- Equipment status indication
- Control panel signaling
Procurement Notes
Verify end-of-life status prior to procurement as the manufacturer indicates discontinuation. Confirm lead times due to potential production constraints. Ensure compatibility with existing PCB footprints and driving circuits. Validate RoHS compliance requirements against current project specifications. Review datasheet revisions for any parameter updates before finalizing design-in decisions.
Selection Notes
Select this component when a high-volume audible alert is required for through-hole assemblies. The 15 V rating suits standard logic-level or relay-driven interfaces. Consider the 92 dB output for environments requiring clear auditory feedback. Evaluate the 22 mm form factor against available board space constraints.
