Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix and manufacturer designation when sourcing, as the product line transitioned from CUI Devices to Same Sky. Confirm mechanical dimensions and pin configurations against the official datasheet to ensure compatibility with existing PCB footprints. Cross-reference electrical ratings such as resonant frequency and sound pressure level to match application requirements precisely.

Alarms, Buzzers, And Sirens Selection Notes

Select this component for designs requiring a compact, high-decibel audible indicator. The 30 mm form factor balances size and acoustic performance. Ensure the driving circuit can supply the necessary voltage and current for optimal operation at the 2.8 kHz resonant frequency. Consider the through-hole requirement during PCB layout planning.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the CPT series of piezoelectric buzzers from Same Sky. The series offers various diameters and frequencies to suit different acoustic needs. The CPT-3075-90T specifically targets applications needing a mid-range diameter with high volume output.
