Speakers datasheet and documents for CMS-151135-078L100
Speakers Overview
The Same Sky CMS-151135-078L100 is a micro speaker featuring a rectangular frame measuring 15 mm by 11 mm. It utilizes a neodymium magnet and a PEEK cone to deliver audio performance with an impedance of 8 ohms and a power rating of 0.7 W. The unit includes wire leads with a connector for board mounting and offers IPX7 water resistance.
Speakers Feature Summary
- Constructed with a PEEK cone and neodymium magnet for acoustic efficiency
- Features integrated wire leads with a connector for simplified assembly
- Provides IPX7 rated environmental protection against water immersion
Speakers Applications
- Portable consumer electronics requiring compact audio output
- Medical devices needing sealed acoustic components
- Industrial equipment operating in humid or wet environments
Speakers Procurement Notes
Verify the specific suffix (e.g., -67) required for your application, as it dictates the connector type and lead configuration. Confirm that the 8-ohm impedance matches your amplifier output capabilities. Ensure the rectangular footprint dimensions fit within the designated PCB area without obstruction.
Speakers Selection Notes
Select this component when a small rectangular form factor is necessary alongside high moisture resistance. The integrated connector simplifies wiring compared to solder-pad alternatives. Consider the 0.7 W power handling limit relative to the expected drive levels in the target system design.
Speakers Part Context
This model belongs to the Same Sky CMS series of micro speakers. It shares the 15x11 mm rectangular housing with other variants but differs in terminal style and magnetic material. The series provides options for both panel and board mounting configurations across various impedance values.
Speakers Replacement Considerations
Direct substitutes include CMS-151135-078L100B-67 which maintains identical electrical and mechanical specifications. Alternative models like CMS-15113-076SP offer similar dimensions but utilize solder pads instead of wire leads.
