CDS-40304

Overview

The Same Sky CDS-40304 is an oval electromagnetic speaker with a 2W power rating and 4-ohm impedance. It features a 40x30mm form factor, measuring 7.1mm in depth. The unit delivers a sound pressure level of 102 dB at a resonant frequency of 400Hz. It utilizes Nd-Fe-B magnets and operates within a temperature range of -30°C to +70°C. Wire leads are provided for termination, and the device supports frame mounting.

Feature Summary

• Electromagnetic transduction using Nd-Fe-B magnet technology
• Oval physical geometry optimized for compact installations
• High acoustic output relative to size with wire lead termination

Applications

• Consumer electronics requiring compact audio output
• Industrial control panels needing audible alerts
• Medical devices with space-constrained enclosures

Procurement Notes

Verify the specific suffix (e.g., L1003) against official documentation to confirm exact electrical tolerances and mechanical dimensions. Ensure the operating environment stays within the specified -30°C to +70°C range. Confirm that wire lead termination matches your assembly requirements rather than surface mount options.

Selection Notes

Select this component when a low-profile oval speaker is required for high-volume production. The 4-ohm impedance suits standard amplifier outputs. Consider the 102dB SPL for applications needing clear audibility without excessive power consumption. Validate that the 7.1mm depth fits within the available chassis clearance.

Part Context

This model belongs to the Same Sky series of electromagnetic speakers designed for cost-effective audio solutions. The CDS series typically offers standardized dimensions to facilitate easy integration into various electronic housings. These components are engineered for reliability in mass-produced consumer and industrial goods.

Replacement Considerations

Direct substitutes must match the 40x30mm oval footprint, 4-ohm impedance, and similar SPL characteristics. Verify pinout or lead configuration compatibility if replacing in existing assemblies. Cross-reference with manufacturer cross-reference lists for confirmed equivalent part numbers.
