CDS-40304-L1003

Overview

The Same Sky CDS-40304-L1003 is an electromagnetic speaker designed for audio output applications. It features a rectangular oval shape with dimensions of 40 mm in length, 30 mm in width, and 7.1 mm in depth. The unit operates at a resonant frequency of 400 Hz and presents a nominal impedance of 4 ohms. It supports a maximum power rating of 2 watts and delivers a sound pressure level of 102 dBa. The device utilizes Nd-Fe-B magnets and connects via wire leads, functioning within a temperature range of -30°C to +70°C.

Feature Summary

• Electromagnetic transduction using neodymium iron boron (Nd-Fe-B) permanent magnets
• Frame mount installation style with integrated wire leads for direct connection
• Oval acoustic geometry optimized for compact enclosure integration

Applications

• Consumer electronic audio output devices
• Industrial control panel signaling
• Medical equipment audible alerts

Procurement Notes

Verify the specific manufacturer part number against official Same Sky documentation to confirm electrical parameters and physical dimensions. Ensure the operating environment remains within the specified -30°C to +70°C temperature range. Confirm that the 4-ohm impedance and 2-watt power handling align with the driving circuit capabilities. Check for RoHS compliance status through the official datasheet before final procurement.

Selection Notes

Select this component when a compact, high-output electromagnetic speaker is required for frame mounting. The 40x30 mm footprint suits space-constrained designs needing 102 dBa performance at 400 Hz. Verify that the wire lead termination method matches the system wiring architecture. Consider the thermal limits and ensure the application does not exceed the maximum operating temperature of +70°C during continuous use.

Part Context

This model belongs to the Same Sky electromagnetic speaker portfolio, formerly associated with CUI Devices. It represents a standard solution for general-purpose audio signaling and voice reproduction in small form factor electronics. The design prioritizes mechanical stability and acoustic efficiency within a low-profile rectangular package suitable for mass production environments.

Replacement Considerations

Consult official Same Sky catalogs for verified substitute part numbers with matching impedance, dimensions, and mounting configurations. Do not assume cross-compatibility with generic speakers without verifying electrical and mechanical specifications.
