CT-1205C-SMT-TR

Alarms, Buzzers, And Sirens Overview

The CT-1205C-SMT-TR is a surface-mount magnetic audio buzzer manufactured by Same Sky. It operates on a rated voltage of 5 VDC with a supply current of 30 mA. The device produces a single-tone signal at a frequency of 2.4 kHz, achieving a sound pressure level of 90 dBA measured at 5 V and 10 cm distance. Its physical dimensions are 12.80 mm x 12.80 mm in footprint with a maximum height of 10.30 mm. The component supports an operating temperature range from -30°C to 70°C and features top-port sound emission.

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix C against official datasheets to confirm internal driver integration, as variations exist within the CT series. Ensure the ordering code matches the required surface-mount package type. Confirm RoHS compliance status through manufacturer documentation prior to procurement. Validate that the 5 VDC rating aligns with target system power supplies.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when internal driving capability is required to reduce external circuit complexity. The 12.80 mm square form factor suits compact designs where through-hole options are unavailable. Verify that the 90 dBA acoustic output meets environmental noise requirements. Consider the 10.30 mm height constraint for enclosure clearance. Ensure compatibility with automated surface-mount placement equipment.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the CT series of audio magnetic buzzers from Same Sky. The series offers various mounting styles and voltage ratings. The CT-1205 variant specifically denotes the 12.80 mm footprint size. The SMT suffix indicates surface-mount termination. The C suffix typically differentiates internal versus external drive configurations within the product line.

Alarms, Buzzers, And Sirens Replacement Considerations

Cross-reference the CT-1205H-SMT-TR if external drive circuits are preferred instead of internal drivers. Verify pinout compatibility before substituting other surface-mount buzzers. Check dimensional tolerances to ensure mechanical fit within existing PCB footprints.
