CMS-4042-0525SP

Speakers Overview

The CMS-4042-0525SP is a general-purpose micro speaker manufactured by Same Sky. It features a 40 mm round frame with a depth of 4.2 mm and utilizes a PEN cone material. The unit is equipped with a Neodymium Iron Boron (Nd-Fe-B) magnet and operates at an impedance of 25 ohms. It has a power rating of 0.5 W and a resonant frequency range of 280 Hz to 3.6 kHz. The component terminates via solder pads for surface mounting.

Speakers Feature Summary

• Utilizes a neodymium iron boron magnet for efficient magnetic flux density
• Features a PEN cone design for acoustic performance
• Designed for panel mount installation using solder pad termination

Speakers Applications

• General purpose audio output in consumer electronics
• Intercom systems requiring compact speakers
• Portable electronic devices with limited space constraints

Speakers Procurement Notes

Verify the specific impedance value of 25 ohms against circuit requirements, as this differs from standard 8-ohm configurations. Confirm that the 4.2 mm depth fits within the available enclosure space. Ensure soldering processes are compatible with the specified pad layout and do not exceed thermal limits defined in the official datasheet.

Speakers Selection Notes

Select this model when a 25-ohm impedance is required for direct driver matching or specific amplifier output stages. The 40 mm diameter provides a balance between size and sound pressure level. Consider the 0.5 W power handling capability relative to the intended signal levels to prevent distortion or damage during peak operation.

Speakers Part Context

This component belongs to the Same Sky speaker portfolio, formerly associated with CUI Devices. The manufacturer specializes in audio, interconnect, and motion control solutions. This specific part represents a standard micro-speaker option designed for integration into various electronic assemblies requiring reliable audio transduction.

Speakers Replacement Considerations

Cross-reference with CMS-4042-0525SP equivalents from other manufacturers if supply chain issues arise. Verify that any substitute maintains the 25-ohm impedance, 40 mm diameter, and 4.2 mm depth to ensure mechanical and electrical compatibility.
