• Through-hole PC pin termination for PCB integration
• Compact 17mm diameter housing

Applications

• General purpose audio indication
• Alarm systems
• Siren applications

Procurement Notes

Verify the specific suffix B0 against official Murata documentation to confirm exact acoustic and electrical characteristics. Confirm that the through-hole PC pin configuration matches the target PCB layout requirements. Ensure the operating temperature range of -20°C to +70°C aligns with the intended environmental conditions. Cross-reference the datasheet version to ensure compatibility with current manufacturing specifications.

Selection Notes

Select this component when a compact, low-voltage piezoelectric sounder is required for direct board mounting. The 3V nominal rating suits battery-powered or low-voltage logic circuits. Verify that the external drive capability meets the impedance and voltage swing requirements of the driving circuitry before finalizing the design.

Part Context

This part belongs to the Murata PKM series of piezoelectric sounders. These components are engineered for reliable audio signaling in consumer and industrial electronics. The series offers various diameters and mounting options to accommodate different enclosure constraints and acoustic performance needs.

Replacement Considerations

Consult official Murata documentation for verified substitute part numbers within the PKM series. Ensure any replacement maintains the same 17mm diameter, 3V operation, and through-hole termination style.
