Alarms, Buzzers, And Sirens Procurement Notes
Verify the specific suffix 'FL' indicates wire leads rather than through-hole pins, as variants like EFM-290EDQ use different mounting styles. Confirm the active status and availability from authorized distributors before ordering. Ensure the 9V rating matches the target circuit design requirements.
Alarms, Buzzers, And Sirens Selection Notes
Select this component when a 9V piezo buzzer with pre-attached wires is required. Consider the 3.2kHz frequency and 90dB(A) sound pressure level at 9VDC for audibility needs. Compare against the EFM-290EK if a 7.5V rating is preferred or the EFM-290EDQ if through-hole mounting without wires is needed.
Alarms, Buzzers, And Sirens Part Context
This part belongs to the East Electronics EFM-290 series of piezoelectric buzzers. The series offers various voltage ratings and mounting options, including through-hole and wire-lead configurations. The EFM-290EDFL specifically denotes the 9V variant with wire leads, distinct from other series members like the EFM-290EDQ.
Alarms, Buzzers, And Sirens Replacement Considerations
The EFM-290EDQ is a similar 9V piezo buzzer but uses through-hole mounting instead of wire leads. The EFM-290EK is a 7.5V alternative within the same family. Verify mechanical dimensions and electrical characteristics before substituting.
