Speakers datasheet and documents for CMS-131304-SMT-TR

CMS-131304-SMT-TR

Speakers Overview

The CMS-131304-SMT-TR is a surface-mount audio transducer manufactured by Same Sky. It features a square piezoelectric design with dimensions of 13 mm x 13 mm x 4 mm. The component operates at a resonant frequency of 900 Hz and has an impedance of 8 ohms. It supports a power rating of 0.7 W and utilizes SmCo magnetic materials for efficient sound generation.

Speakers Feature Summary

Surface-mount construction for automated PCB assembly
Piezoelectric technology for reliable acoustic output
Compact square form factor suitable for space-constrained designs

Speakers Applications

Portable electronic devices requiring compact audio alerts
Industrial control panels needing visual-free status indicators
Consumer appliances utilizing small form-factor speakers

Speakers Procurement Notes

Verify the specific datasheet version to confirm RoHS compliance and material composition details. Ensure that the surface-mount footprint matches the intended PCB layout, as soldering parameters must align with the manufacturer's reflow profile recommendations for optimal joint integrity.

Speakers Selection Notes

Select this component when a low-profile, high-efficiency piezoelectric solution is required. Consider the 8-ohm impedance and 0.7 W power handling against the driving circuit capabilities. The 900 Hz frequency response defines its suitability for tone generation rather than full-range audio reproduction.

Speakers Part Context

This model belongs to Same Sky's portfolio of surface-mount audio transducers. It represents a shift towards miniaturized components that replace traditional through-hole speakers in modern electronics manufacturing processes.
