CDS-4221-44L100

Overview

The CDS-4221-44L100 is a general-purpose electromagnetic speaker manufactured by Same Sky. It features a square frame with top porting and operates at an impedance of 4 Ohms. The rated power is 4 W, with a maximum power handling of 8 W. The frequency response spans from 230 Hz to 20 kHz, with a self-resonant frequency of 230 Hz. Sensitivity is 83 dBA measured at 1W/1m. The physical dimensions are 42.5 mm x 42.5 mm x 21.6 mm. It utilizes a Neodymium Iron Boron magnet and polyester cone material.

Feature Summary

• Top-port design for optimized acoustic output direction
• Square frame construction for compact mounting integration
• High-power handling capability suitable for demanding audio applications

Applications

• General purpose audio output devices
• Electronic equipment requiring robust sound reproduction
• Industrial control panels with audio feedback needs

Procurement Notes

Verify the specific ordering suffix and packaging configuration against the official manufacturer datasheet before procurement. Confirm that the component meets all required environmental standards, such as RoHS compliance, for your target market. Ensure mechanical fitment matches the enclosure design constraints regarding depth and mounting holes.

Selection Notes

Select this model when a square form factor and high power handling are required. The 4 Ohm impedance and 83 dB sensitivity offer a balance between driver load and acoustic efficiency. Consider the 21.6 mm depth constraint during mechanical design. Verify compatibility with the intended amplifier output characteristics for optimal performance.

Part Context

This component belongs to the CDS series of rectangular micro-speakers from Same Sky. The series is designed for various electronic applications requiring reliable audio transduction. The CDS-4221 variant specifically addresses needs for higher power handling within a square footprint compared to smaller circular or rectangular alternatives in the lineup.

Replacement Considerations

Check for direct substitutes within the Same Sky CDS series that match the 42.5mm square dimension and 4 Ohm impedance. Verify that any replacement maintains the same top-port orientation and similar sensitivity ratings to ensure consistent acoustic performance in the existing enclosure.
