CMS-3012-18T

Speakers Overview

The CMS-3012-18T is a miniature oval speaker manufactured by Same Sky, formerly CUI Devices. It features a 30 mm x 12.8 mm frame with an 8 Ohm impedance and a 1 W power rating. The unit utilizes a Neodymium Iron Boron magnet and a Polyethylene Terephthalate cone. Key electrical parameters include a self-resonant frequency of 500 Hz to 4 kHz and a sound pressure level of 99 dB. The component operates within a temperature range of -25°C to +65°C and uses wire leads for termination.

Speakers Feature Summary

• Compact oval form factor designed for space-constrained applications
• High-efficiency neodymium magnet construction
• Polyethylene terephthalate diaphragm material

Speakers Applications

• Portable electronic devices
• Miniature audio equipment
• Embedded sound modules

Speakers Procurement Notes

Verify the specific datasheet revision when sourcing, as manufacturer transitions from CUI Devices to Same Sky may result in documentation updates. Confirm that the wire lead termination style matches the target PCB or harness design requirements before finalizing procurement orders.

Speakers Selection Notes

Select this model for applications requiring a low-profile oval shape with standard 8 Ohm impedance. Ensure the available mounting space accommodates the 30 mm length and 12.8 mm depth dimensions. Verify that the 1 W power handling capacity aligns with the system's audio output levels.

Speakers Part Context

This component belongs to the Same Sky miniature speaker series, which provides various sizes and shapes for audio transduction. The CMS-3012-18T specifically addresses the need for compact, high-output speakers in small enclosures, maintaining compatibility with standard audio driver circuits.

Speakers Replacement Considerations

Check for direct cross-references in distributor databases. Ensure any substitute maintains the 30x12.8mm footprint, 8 Ohm impedance, and wire lead termination to fit existing mechanical and electrical designs without modification.
