CDS-40304-L1006

Overview

The CDS-40304-L1006 is a general-purpose rectangular micro-speaker manufactured by Same Sky. It features a 4 Ohm impedance and a rated power of 2 W, with a maximum power handling capacity of 3 W. The device operates within a frequency range of 320 Hz to 20 kHz and has a self-resonant frequency of 400 Hz. It delivers a sound pressure level (SPL) of 79 dBA when tested at 1W/1M. The speaker utilizes a paper/cloth cone and an Nd-Fe-B magnet. Its physical dimensions are 40.00 mm in length by 30.00 mm in width, with a maximum installation height of 7.10 mm. The unit employs top porting and pad termination.

Feature Summary

• Rectangular form factor with top porting for directional sound projection
• Neodymium magnet assembly paired with a paper or cloth diaphragm
• Pad-based termination method for direct circuit board integration

Applications

• General purpose audio output devices
• Medical equipment acoustic signaling
• Industrial control panel indicators

Procurement Notes

Verify the specific suffix L1006 against official documentation to confirm wire lead specifications, as suffixes may alter termination type without changing core acoustic function. Ensure compatibility with RoHS3 standards if required by your manufacturing environment. Cross-reference the manufacturer part number with authorized distributor databases to confirm current production status and availability constraints before finalizing procurement plans.

Selection Notes

Select this component when a compact rectangular speaker with top porting is required for space-constrained enclosures. The 4 Ohm impedance and 2 W rating suit low-power consumer and industrial applications. Consider the 79 dBA sensitivity for volume requirements and verify that the 320 Hz lower frequency limit meets the application's bass response needs. Ensure the PCB layout accommodates the specified pad termination style.

Part Context

This model belongs to the CDS series of miniature speakers from Same Sky, formerly known as CUI Devices. The series focuses on rectangular micro-speakers designed for integration into various electronic devices. The CDS-40304 variant specifically denotes the 40mm x 30mm footprint size within this product line, offering a balance between acoustic performance and physical compactness for embedded audio solutions.

Replacement Considerations

The CDS-40304-L100 is a verified substitute part number within the same series. Verify mechanical mounting hole patterns and electrical pinout compatibility before substitution. Ensure the replacement unit maintains the required 4 Ohm impedance and 2 W power rating to match the original design specifications.
