CDS-4028-16

Overview

The CDS-4028-16 is a general-purpose electromagnetic speaker manufactured by Same Sky. It features a rectangular frame with dimensions of 40 x 28.3 mm and a depth of 12 mm. The unit has an impedance of 16 Ohms and a rated power of 2 W, with a maximum power handling of 3 W. It utilizes a cloth cone and a neodymium magnet. The frequency response ranges from 360 Hz to 20 kHz, with a self-resonant frequency of approximately 400 Hz. The sound pressure level is 86 dBA at 1W/1m. Operating temperature spans -20°C to 60°C.

Feature Summary

• Rectangular frame design for compact integration
• Neodymium magnet construction for efficient performance
• Cloth cone material for durability

Applications

• General purpose audio output devices
• Miniature electronic enclosures
• Portable consumer electronics

Procurement Notes

Verify the specific impedance value of 16 Ohms against circuit requirements to ensure proper matching. Confirm physical dimensions of 40 x 28.3 mm fit the designated enclosure space. Check RoHS compliance status if environmental regulations apply to the final product assembly.

Selection Notes

Select this model when a 16 Ohm impedance is required for the audio driver stage. Consider the 86 dBA sensitivity for applications needing moderate acoustic output without excessive amplification. Ensure the operating temperature range of -20°C to 60°C aligns with the intended environment.

Part Context

This component belongs to the CDS series of miniature speakers from Same Sky. These units are designed for space-constrained applications requiring reliable electromagnetic transduction. The series offers various impedance and size options to suit different audio system designs.

Replacement Considerations

Direct substitutes must match the 16 Ohm impedance and similar physical footprint. Verify that alternative models maintain comparable sensitivity and power ratings to avoid performance degradation in existing circuits.
