CDM-20008

Overview

The CDM-20008 is a 20 mm round frame general-purpose speaker manufactured by Same Sky. It features an 8 Ohm impedance and a power handling capacity of 300 mW (0.3 W). The unit utilizes a Neodymium Iron Boron magnet and a PET cone material. Key electrical parameters include a resonant frequency of 560 Hz, a sound pressure level of 92 dBA, and an operating frequency range of 448 Hz to 7 kHz. The component has a depth of 3.1 mm and uses solder pad connections for board mounting.

Feature Summary

• Utilizes a neodymium iron boron magnet for efficient electromagnetic conversion
• Features a PET cone construction for acoustic performance
• Designed for direct board mounting via solder pads
• Compact physical profile suitable for space-constrained applications

Applications

• General purpose audio output devices
• Miniature electronic enclosures requiring board-mounted speakers
• Consumer electronics with limited internal volume

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required impedance and power ratings. Confirm that the package type matches the target PCB footprint. Check RoHS compliance status if restricted substances are a constraint for the final assembly. Ensure the solder pad configuration aligns with the manufacturing process.

Selection Notes

Select this component when a 20 mm round form factor is required for the design. Consider the 8 Ohm impedance for matching with amplifier outputs. Evaluate the 92 dBA sensitivity against the desired volume requirements. Verify that the 3.1 mm depth fits within the available chassis clearance. Assess the frequency response range against the intended audio content specifications.
