• High sound pressure level output relative to input voltage
• Compact form factor suitable for space-constrained applications

Applications

• Alarm systems requiring audible alerts
• Buzzer circuits in consumer electronics
• Siren devices for safety warnings

Procurement Notes

Verify the exact suffix 'LFMP' against official DB Products documentation to confirm lead-free status and specific packaging configuration. Ensure the part number matches the required acoustic specifications before procurement, as minor suffix variations may indicate different mechanical or electrical tolerances not covered in general summaries.

Selection Notes

Select this component when a high-decibel output is required from a low-voltage source. The internal drive mechanism simplifies circuit design by reducing the need for external oscillators. Confirm that the 3.2 kHz frequency aligns with the target application's auditory requirements and that the 90 mA current draw is supported by the power supply.

Part Context

DB Products specializes in acoustic components, including buzzers and transducers. This model belongs to their line of electromagnetic transducers designed for reliable audio signaling. The company has produced various acoustic models since 1976, focusing on combining human hearing sensitivity with electronic components.
