CDS-4051-32-SP

Overview

The CDS-4051-32-SP is a round, general-purpose electromagnetic speaker manufactured by Same Sky. It features a 40 mm diameter frame with a height of 5.1 mm and utilizes a neodymium iron boron magnet. The unit has a 32 Ohm impedance and a rated power of 250 mW (maximum 3 W). Its frequency response ranges from 600 Hz to 6 kHz, with a self-resonant frequency of 480 Hz. The speaker delivers a sound pressure level of 92 dBA at 1W/1M and uses a PET cone material with solder pad termination.

Feature Summary

• Round frame design with top port configuration
• Neodymium iron boron magnetic structure
• PET cone material for diaphragm construction

Applications

• General purpose audio output devices
• Miniature electronic enclosures
• Medical application audio components

Procurement Notes

Verify the specific suffix SP indicates the standard packaging format upon ordering. Confirm RoHS compliance status matches current regulatory requirements for your region. Ensure the 32 Ohm impedance aligns with the amplifier output specifications. Check for any recent design change notices that may affect physical dimensions or electrical characteristics before finalizing the bill of materials.

Selection Notes

Select this component when a compact, round form factor is required for space-constrained designs. The 32 Ohm impedance suits standard low-power audio amplifiers. Consider the 92 dBA sensitivity for applications requiring moderate acoustic output without excessive drive power. Verify enclosure compatibility with the 5.1 mm height constraint.

Part Context

This part belongs to the CDS series of miniature rectangular and round speakers from Same Sky. These components are designed for integration into portable electronics and medical devices where size and weight are critical factors. The series offers various impedance and power ratings to match different driver capabilities.

Replacement Considerations

Direct substitutes include other 40mm round speakers with similar 32 Ohm impedance and 250 mW rating. Verify mechanical mounting hole patterns and terminal types. Compare frequency response curves to ensure acoustic performance matches the original design intent.
