Alarms, Buzzers, And Sirens Procurement Notes

Verify the manufacturer part number against official Ole Wolff Electronics Inc documentation to ensure authenticity. Confirm that the surface-mount package dimensions and thermal characteristics align with your PCB layout requirements. Check for RoHS compliance status if required by your manufacturing standards. Ensure the driving circuitry matches the 3V rated voltage specifications before procurement.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a low-profile, surface-mount magnetic buzzer is required for space-constrained designs. The 4mm square footprint suits dense PCB layouts. Consider the 3V operating voltage and single-tone nature for simple alert applications. Verify that the external drive circuit can supply the necessary current for adequate sound pressure levels without exceeding thermal limits.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the Ole Wolff Electronics Inc buzzer family, categorized under alarms, buzzers, and sirens. It complements other SMD audio components like the OWPB series, offering a magnetic transduction method distinct from piezo alternatives. The product line focuses on externally driven transducers for various consumer and industrial audio signaling needs.

Alarms, Buzzers, And Sirens Replacement Considerations

Cross-reference with similar 4x4mm SMD magnetic buzzers from other manufacturers if supply constraints exist. Ensure replacement parts match the 3V rating and pinout configuration. Verify that substitute components meet the same -40°C to 85°C operating temperature range and mechanical height constraints.
