CSS-40408N

Speakers Overview

The CSS-40408N is a general-purpose speaker manufactured by Same Sky, formerly CUI Devices. It features an 8 Ohm impedance and a 5 W power rating with a maximum capacity of 8 W. The unit utilizes a neodymium iron boron magnet and a polyethylene terephthalate (PET) cone. Its frequency range spans from 352 Hz to 20 kHz, with a self-resonant frequency of 440 Hz. The device delivers a sound pressure level of 100 dBA at 1W/100mm. Dimensions are 40.10 mm x 40.10 mm in size with a maximum installation height of 14.50 mm. It employs top porting and solder lug termination.

Speakers Feature Summary

• Utilizes a neodymium iron boron magnetic structure for efficient audio output.
• Features a polyethylene terephthalate cone material for durability.
• Designed with top porting configuration for acoustic projection.
• Constructed with a circular shape and square frame geometry.

Speakers Applications

• General purpose audio reproduction systems
• Electronic devices requiring compact speakers
• Medical application audio components

Speakers Procurement Notes

Verify the manufacturer designation as Same Sky, formerly CUI Devices, to ensure correct sourcing. Confirm RoHS3 compliance status prior to integration. Check for moisture sensitivity classification requirements if applicable to the assembly process. Ensure the ordering suffix matches the specific packaging or lead configuration needed for the design.

Speakers Selection Notes

Select this component when a 5 W rated speaker with 8 Ohm impedance is required. The 100 dBA efficiency supports applications needing high volume output from low power inputs. The 40 mm form factor fits standard enclosure spaces. Verify that the top port orientation aligns with the mechanical design constraints of the target housing.

Speakers Part Context

This part belongs to the CSS series of speakers from Same Sky. It represents a transition from the previous CUI Devices branding. The series includes various sizes and power ratings. This specific model focuses on general-purpose utility with robust magnetic materials and standard PET cone construction for reliable performance across a wide frequency band.

Speakers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Evaluate other Same Sky CSS series models for dimensional compatibility. Cross-reference impedance and power ratings with alternative manufacturers ensuring matching frequency response characteristics.
