CMS-181325-078L100

Speakers Overview

The CMS-181325-078L100 is a rectangular micro speaker manufactured by Same Sky. It features an 8-ohm impedance and a power rating of 0.7 W (700 mW). The device utilizes a neodymium magnet and a PEEK cone for acoustic performance. Key electrical parameters include a resonant frequency of 800 Hz and a sound pressure level of 93 dBA. The unit measures 18.00 mm in length, 13.00 mm in width, and 2.50 mm in height. It employs wire leads with a connector for termination and offers IP67 environmental protection.

Speakers Feature Summary

• IP67 waterproof rating for reliable operation in wet environments
• PEEK cone material provides durability and consistent acoustic response
• Neodymium magnet ensures high efficiency in a compact form factor
• Rectangular frame design facilitates integration into space-constrained enclosures

Speakers Applications

• Medical devices requiring waterproof audio components
• Consumer electronics exposed to moisture or humidity
• Industrial equipment needing durable micro speakers
• Portable electronic devices with limited internal space

Speakers Procurement Notes

Verify the specific suffix code on the datasheet to confirm connector type and lead configuration. Ensure the IP67 rating aligns with your enclosure sealing strategy. Confirm mechanical dimensions against your PCB layout and housing constraints. Check RoHS compliance status if required by your manufacturing standards. Validate the operating temperature range for your intended environment.

Speakers Selection Notes

Select this component when a waterproof micro speaker is required for rectangular spaces. The 8-ohm impedance matches standard audio amplifier outputs. The 0.7 W power handling suits low-to-medium volume applications. Consider the 93 dBA sensitivity for efficient drive requirements. The wire lead termination simplifies assembly compared to surface mount options.

Speakers Part Context

This part belongs to the CMS series of micro speakers from Same Sky. The series includes various sizes and configurations for different audio needs. The CMS-181325 variant specifically targets applications needing a balance of size and output. Previous iterations may have used PET cones; this model specifies PEEK for enhanced performance.

Speakers Replacement Considerations

Check for CMS-181325-078SP as a potential alternative with similar electrical characteristics but different termination methods. Verify that any substitute maintains the IP67 rating if environmental sealing is critical. Ensure the replacement fits the 18x13mm footprint without modification.
