CS45-04D20-28-1

Speakers Overview

The CS45-04D20-28-1 is a general-purpose speaker manufactured by Challenge Electronics. It features a square form factor with dimensions of 45.0 mm x 45.0 mm and a seated height of 28.1 mm. The unit operates at an impedance of 4 Ohms and has a power rating of 4.00 W. It exhibits a sound pressure level efficiency of 110 dB and a self-resonant frequency of 200 Hz.

Speakers Feature Summary

• Square top-mount design for compact integration
• High sensitivity output via solder tab connections

Speakers Applications

• General purpose audio reproduction
• Consumer electronics enclosures
• Industrial control panels

Speakers Procurement Notes

Verify the specific datasheet version to confirm electrical tolerances and mechanical drawings before finalizing the design. Ensure that the mounting space accommodates the 28.1 mm height and 45.0 mm footprint. Confirm that the 4 Ohm impedance matches the amplifier output requirements for optimal performance.

Speakers Selection Notes

Select this component when a low-profile, high-efficiency square speaker is required for general audio tasks. The 110 dB sensitivity allows for adequate volume levels with standard drive signals. Consider the 4.00 W power handling limit when designing the signal chain to prevent thermal damage during continuous operation.

Speakers Part Context

This model belongs to the Challenge Electronics CS45 series of square speakers. The series offers various configurations differing in diameter, height, and impedance. The CS45-04D20-28-1 specifically denotes the 4 Ohm variant with the 28.1 mm height profile within this product line.

Speakers Replacement Considerations

Direct substitutes are not explicitly listed in public documentation. Verify compatibility based on matching impedance, power rating, and physical dimensions when selecting alternative components.
