Speakers datasheet and documents for CMS-25145-18SP-65
Speakers Overview
The CMS-25145-18SP-65 is a miniature speaker manufactured by Same Sky. It features an 18mm diameter and a 158mm² effective radiating area. The unit operates with a nominal impedance of 8 ohms and has a power handling capacity of 0.5 watts. Key acoustic specifications include a sensitivity of 93 dB SPL at 1 watt measured at 10cm, and a resonant frequency (Fs) of 1.2 kHz. The component utilizes a black finish and is designed for board mounting applications requiring compact audio output.
Speakers Feature Summary
- Compact physical dimensions suitable for space-constrained electronic assemblies
- High acoustic efficiency providing clear sound projection relative to size
- Standardized electrical characteristics compatible with common audio driver circuits
Speakers Applications
- Portable consumer electronics requiring small form factor audio
- Industrial control panels needing audible status indicators
- Medical devices with limited internal volume for alarm systems
Speakers Procurement Notes
Verify the specific suffix configuration against the manufacturer's current datasheet to ensure compatibility with required acoustic performance metrics. Confirm RoHS compliance status and material composition details prior to integration into regulated end-products. Cross-reference the manufacturing date code to avoid obsolete inventory that may exhibit degraded adhesive properties or diaphragm integrity over time.
Speakers Selection Notes
Select this model when system constraints demand a sub-20mm diameter speaker with moderate power handling. Evaluate the 1.2 kHz resonant frequency against target application bandwidth requirements to ensure adequate mid-range reproduction. Compare the 93 dB sensitivity against available alternatives to balance amplifier drive capabilities with desired output levels in enclosed spaces.
Speakers Part Context
This component belongs to Same Sky's miniature speaker portfolio, formerly associated with CUI Devices. The series focuses on delivering reliable audio performance in reduced physical footprints. These speakers are engineered for high-volume manufacturing processes and consistent acoustic tolerances across production batches.
Speakers Replacement Considerations
Direct substitutes must match the 18mm diameter and 8-ohm impedance. Verify that alternative models maintain similar sensitivity ratings to prevent amplifier redesign. Ensure mechanical mounting hole patterns align with existing PCB layouts to facilitate drop-in replacement without structural modifications.
