CMS-3048-058SP

Speakers Overview

The CMS-3048-058SP is a miniature electromagnetic speaker manufactured by Same Sky (Formerly CUI Devices). It features an 8 Ohm impedance and a rated power of 200 mW, with a maximum power handling capacity of 400 mW. The unit delivers a sound pressure level of 89 dBA and operates within a frequency range of 550 Hz to 13 kHz, centered around a self-resonant frequency of 550 Hz. Designed for top-port applications, it utilizes a polyethylene terephthalate (PET) cone and a Neodymium Iron Boron (NdFeB) magnet. The component measures 30.00 mm in diameter with a maximum installation height of 4.00 mm and employs pad termination for circuit board mounting.

Speakers Feature Summary

• Utilizes a neodymium iron boron magnetic structure for high performance in a compact form factor.
• Features a polyethylene terephthalate cone material for durability and acoustic consistency.
• Designed with a top-port configuration to optimize sound projection in enclosed spaces.
• Supports surface mount or through-hole pad termination for flexible PCB integration.

Speakers Applications

• Medical devices requiring compact audio indicators
• Portable consumer electronics with space constraints
• Industrial control panels needing status alerts
• Automotive interior signaling systems

Speakers Procurement Notes

Verify the specific ordering suffix and packaging quantity against the manufacturer's current datasheet before procurement. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the selected variant matches the required terminal type and acoustic specifications for your enclosure design.

Speakers Selection Notes

Select this component when a small footprint with moderate acoustic output is required. The 8 Ohm impedance suits standard audio driver circuits. Consider the 89 dBA sensitivity for environments where clear audible feedback is necessary without excessive power consumption. Verify that the 4.00 mm height fits within the available chassis depth.

Speakers Part Context

This part belongs to the CLS series of miniature speakers from Same Sky. The series is characterized by small dimensions suitable for portable and medical applications. The CLS0301MA is listed as obsolete with the CMS-3048-058SP recommended as a replacement, indicating a product line evolution toward updated acoustic or manufacturing standards while maintaining similar form factors.

Speakers Replacement Considerations

The CLS0301MA is identified as an obsolete predecessor. The CMS-3048-058SP is the manufacturer-recommended substitute. Verify mechanical fit and electrical parameters when transitioning from older inventory to ensure compatibility with existing designs.
