Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required voltage ratings and acoustic specifications. Confirm that the through-hole package dimensions align with the target printed circuit board layout before finalizing procurement orders.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a continuous tone signal is required at 3.6kHz. Ensure the system supply voltage remains within the 7V to 12V operational window to maintain the specified 85dB sound pressure level. Consider the thermal environment to guarantee operation within the -20°C to +70°C range.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the EFM-290 series of piezoelectric buzzers produced by East Electronics. The series includes various variants differentiated by voltage ratings, acoustic output levels, and physical dimensions. The EFM-290EK specifically denotes the 7.5V rated variant with a 40mm form factor.

Alarms, Buzzers, And Sirens Replacement Considerations

Cross-reference with other East Electronics models in the EFM-290 family, such as the EFM-290EDQ, if different voltage or dimensional requirements are necessary. Verify pinout and mounting hole patterns match the existing design when substituting.
