CDS-15158-SMT-TR

Overview

The CDS-15158-SMT-TR is a rectangular micro-speaker manufactured by Same Sky. It features an 8 Ohm impedance and a rated power of 300 mW, with a maximum power handling capacity of 500 mW. The device delivers an efficiency of 87 dBA when tested at 300 mW/100mm. Its frequency response ranges from 680 Hz to 20 kHz, with a self-resonant frequency of 850 Hz. The speaker utilizes a PET diaphragm and an Sm2Co17 magnet. It has a top port location and measures 15.00 mm x 15.00 mm in size with a maximum installation height of 5.00 mm.

Feature Summary

Top-port acoustic design for directed sound output
Water-washable construction for durability
Surface mount termination for automated PCB assembly

Applications

Medical applications requiring compact audio solutions
Portable electronic devices needing high-efficiency sound
General purpose audio indicators in consumer electronics

Procurement Notes

Verify the specific suffix and packaging configuration against the official Same Sky datasheet before ordering. Confirm that the surface mount footprint matches your PCB layout requirements. Ensure the thermal and mechanical constraints of the enclosure are compatible with the specified dimensions and mounting style.

Selection Notes

Select this component when a square form factor and top-port sound projection are required. The 8 Ohm impedance suits standard low-voltage audio drivers. Consider the 87 dBA sensitivity for applications demanding higher volume without excessive power consumption. Verify compatibility with washable cleaning processes if used in hygiene-sensitive environments.

Part Context

This part belongs to the CDS series of rectangular micro-speakers from Same Sky. The series is designed for space-constrained applications where traditional round speakers cannot fit. The SMT variant facilitates direct placement on printed circuit boards, supporting modern manufacturing techniques for compact audio modules.
