CDMG16008-03

Overview

The CDMG16008-03 is a miniature magnetic speaker manufactured by Same Sky. It features an 8 Ohm impedance and a rated power of 300 mW, with a maximum power handling of 500 mW. The unit utilizes a Neodymium Iron Boron (NdFeB) magnet and a PET cone. Key electrical parameters include a self-resonant frequency of 600 Hz and a sensitivity of 82 dB SPL at 1 W/10 cm. The physical dimensions are 16 mm in diameter and 2.55 mm in height, with top porting and solder pad terminations.

Feature Summary

• Utilizes a high-strength neodymium iron boron magnet for efficient acoustic output in a compact form factor.
• Features a polyester (PET) cone material designed for durability and consistent performance.
• Incorporates top porting to facilitate sound projection in constrained enclosure designs.

Applications

• Miniature audio devices requiring low-profile speakers
• Medical equipment with space constraints
• Consumer electronics with limited internal volume

Procurement Notes

Verify the specific suffix -03 against the manufacturer's current datasheet to ensure compatibility with required impedance and sensitivity tolerances. Confirm that the solder pad termination style matches the target PCB layout. Check for RoHS compliance status as defined in the latest official documentation before finalizing procurement specifications.

Selection Notes

Select this component when a 16 mm round frame and 2.55 mm depth are required. Ensure the application can accommodate an 8 Ohm load and 300 mW power rating. Consider the 82 dB sensitivity for volume requirements. Verify that the top-port design aligns with the acoustic enclosure strategy compared to rear-port alternatives.

Part Context

This part belongs to the CDMG series of miniature speakers from Same Sky. It shares the 16 mm diameter footprint with other models in the family but differs in power handling and magnetic configuration. The series is designed for applications demanding small size and reliable audio reproduction in portable or embedded systems.

Replacement Considerations

Direct substitutes may include other 16 mm, 8 Ohm, top-port speakers from Same Sky such as the CDM-16008, provided the power rating and sensitivity differences are acceptable for the specific application requirements.
