Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific operating voltage and acoustic output requirements against the datasheet before procurement. Confirm that the surface mount footprint matches the target PCB layout. Ensure the external drive circuit can supply the required 90 mA current at 3.6 V to achieve the specified 88 dB performance level without distortion or thermal issues.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a compact, surface-mountable magnetic buzzer is required for audible signaling. The 2.73 kHz frequency provides a distinct tone suitable for alarms. Consider the 3.6 V nominal operation and ensure the system power rail aligns with these electrical parameters. The small 8.5 mm square profile allows for dense board layouts compared to larger through-hole alternatives.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the Challenge Electronics CT08E series of electromagnetic transducers. The series offers various frequencies and voltage ratings within a consistent 8.5 x 8.5 mm surface mount package. The CT08E-04S273-9 specifically targets applications requiring a 2.73 kHz tone at 3.6 V, distinguishing it from other variants in the family with different acoustic characteristics.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes include other parts from the Challenge Electronics CT08E series with similar dimensions and mounting styles.
