CDS-4528-44L100

Overview

The CDS-4528-44L100 is a general-purpose rectangular micro-speaker manufactured by Same Sky. It features a square frame design with top porting and utilizes an Nd-Fe-B magnet system. The unit operates at a nominal impedance of 4 Ohms with a rated power handling of 4 W and a maximum capacity of 3 W. Its frequency response spans from 200 Hz to 20 kHz, with a self-resonant frequency of 400 Hz. The speaker delivers a sound pressure level of 86 dBA when tested at 1W/1m. Physical dimensions are approximately 45.20mm in length and 28.10mm in width, with a maximum installation height of 11.00mm.

Feature Summary

• Rectangular form factor with a square frame construction for compact integration
• Top ported acoustic design optimized for specific enclosure mounting requirements
• Utilizes Neodymium Iron Boron (Nd-Fe-B) magnetic technology for efficient performance

Applications

• General purpose audio output devices
• Medical electronic equipment requiring compact speakers
• Consumer electronics with limited internal volume

Procurement Notes

Verify the exact part number against official manufacturer documentation before procurement. Confirm that the specific suffix matches the required electrical and mechanical specifications. Check current product status as availability may change. Ensure compliance with relevant environmental regulations such as RoHS standards applicable to your region. Cross-reference datasheet revisions to guarantee compatibility with existing designs.

Selection Notes

Select this component when a rectangular shape fits the mechanical constraints better than circular alternatives. Consider the 4 Ohm impedance for matching with standard amplifier outputs. Evaluate the 200 Hz low-frequency limit to ensure it meets the application's bass requirements. Verify that the 4 W power rating aligns with the intended signal levels to prevent damage.

Part Context

This model belongs to the CDS series of rectangular micro-speakers from Same Sky. The series is designed for applications requiring small footprint audio solutions. These components are commonly used in portable devices and embedded systems where space is limited but reliable audio reproduction is necessary.

Replacement Considerations

Direct substitutes must match the 45.2x28.1mm dimensions and 4 Ohm impedance. Verify that alternative models support similar power ratings and frequency ranges. Ensure the replacement maintains the top-port configuration if enclosure compatibility is critical.
