CMS-251452-18SP

Speakers Overview

The CMS-251452-18SP is a general-purpose piezoelectric speaker manufactured by Same Sky. It features an oval, rectangular frame design with a cloth cone and rare earth magnet construction. The unit operates at an impedance of 8 ohms and delivers a maximum power handling capacity of 1 W. Its frequency response range spans from 350 Hz to 20 kHz, with a resonant frequency specified at 750 Hz. Physical dimensions are 25 mm by 14 mm with a depth of 5.2 mm. Termination is achieved via solder pads for direct circuit board integration.

Speakers Feature Summary

• Oval rectangular frame design optimized for compact audio applications
• Rare earth magnet system ensures efficient acoustic output
• Cloth cone material provides balanced sound reproduction characteristics

Speakers Applications

• General purpose audio indication in consumer electronics
• Status alert systems in industrial control panels
• Portable device speaker integration

Speakers Procurement Notes

Verify the specific manufacturer designation as Same Sky, formerly CUI Devices, when sourcing components. Confirm that the package type utilizes solder pads rather than wire leads or clips. Ensure the 8-ohm impedance matches the driving circuit requirements. Check for RoHS compliance documentation if required by your manufacturing standards. Validate the physical footprint against your PCB layout constraints before finalizing procurement.

Speakers Selection Notes

Select this component when a low-profile, cost-effective audio indicator is required. The 1 W power rating suits low-volume signaling tasks. The 8-ohm impedance is standard for many driver circuits. Consider the 350 Hz lower frequency limit; it is not suitable for full-range music reproduction. The rectangular form factor allows for space-efficient mounting in tight enclosures compared to circular speakers.

Speakers Part Context

This model belongs to the Same Sky line of transducers and audio devices. It serves as a basic audio output solution for embedded systems. The product line emphasizes reliability and standard electrical interfaces. It replaces older CUI Devices branding while maintaining technical specifications. The component is categorized under general-purpose speakers within the broader audio device portfolio.

Speakers Replacement Considerations

Direct substitutes must match the 25x14 mm footprint, 8-ohm impedance, and 1 W power rating. Verify that alternative models support solder pad termination. Ensure the replacement maintains similar frequency response characteristics around the 750 Hz resonance point. Cross-reference mechanical drawings to confirm compatibility with existing mounting structures.
