CDS-5225-54E

Overview

The CDS-5225-54E is a round general-purpose speaker manufactured by Same Sky (Formerly CUI Devices). It features a 52 mm diameter and a depth of 25 mm. The unit has a nominal impedance of 4 Ohms and a power rating of 5 W, with a maximum power handling of 10 W. The frequency response ranges from 160 Hz to 10 kHz, with a self-resonant frequency of approximately 230 Hz. It utilizes a paper cone and an Nd-Fe-B magnet, offering a sensitivity of 87 dB at 1W/1m. The speaker employs tab terminals for connection and is designed for top porting.

Procurement Notes

Verify the specific datasheet version for the CDS-5225-54E as manufacturer documentation may vary. Confirm RoHS compliance status directly with the supplier or official distributor channels. Ensure mechanical dimensions align with enclosure constraints prior to final integration. Check for any recent product change notices regarding material composition or manufacturing location updates.

Selection Notes

Select this component when a round, top-porting speaker is required for general audio applications. The 4 Ohm impedance and 5 W rating suit low-to-moderate power requirements. Verify that the 160 Hz lower frequency limit meets the application's bass response needs. Ensure the 25 mm depth fits within the available housing space. Compare against other CDS series models if different diameters or mounting styles are preferred.

Part Context

This part belongs to the CDS series of rectangular and round micro-speakers produced by Same Sky. The series focuses on compact audio solutions for various electronic devices. The CDS-5225-54E specifically addresses the need for larger diameter speakers within the lineup while maintaining a standard round profile and tab-terminal convenience for easy PCB or chassis mounting.

Replacement Considerations

Direct substitutes include other 52 mm round speakers from the same manufacturer, such as the CDS-5225-54A or CDS-5225-54B, depending on specific sensitivity or impedance variations. Cross-brand replacements require matching the 52 mm diameter, 25 mm depth, 4 Ohm impedance, and tab terminal configuration to ensure physical and electrical compatibility.
