CDMG15008-03A

Overview

The CDMG15008-03A is a miniature electromagnetic loudspeaker manufactured by Same Sky. It features an 8 Ohm impedance and a rated power of 300 mW, with a maximum power handling of 600 mW. The device operates within a frequency range of 900 Hz to 20 kHz and has a resonant frequency of approximately 900 Hz. It delivers a sound pressure level (SPL) of 92 dBA when tested at 1 mW/10 cm. The speaker utilizes a Neodymium Iron Boron magnet and a PEI cone material. Its physical dimensions include a 15 mm diameter frame and a depth of 2.55 mm to 2.8 mm, designed for top porting with solder pad termination.

Feature Summary

• Compact round frame design suitable for space-constrained applications
• High sensitivity output via neodymium magnet structure
• Board mount configuration with solder pad connections

Applications

• Miniature audio devices requiring low profile speakers
• Medical equipment audio components
• Consumer electronics internal sound generation

Procurement Notes

Verify the specific datasheet version for exact mechanical tolerances and RoHS compliance status before integration. Confirm that the solder pad termination method aligns with your PCB assembly process capabilities. Ensure the operating temperature range meets your environmental requirements. Cross-reference the part number with official Same Sky documentation to confirm current production status and any potential obsolescence notices.

Selection Notes

Select this component when a high-sensitivity, low-profile speaker is required for small enclosures. The 8 Ohm impedance matches standard audio driver outputs. Consider the 92 dBA SPL for applications needing clear audio without excessive amplification. The 15 mm diameter allows for easy mounting in tight spaces while maintaining adequate acoustic performance for general purpose use.

Part Context

This model belongs to the CDMG series of miniature speakers from Same Sky. These components are engineered for board-level integration in compact electronic devices. The series emphasizes low profile and high efficiency, utilizing neodymium magnets to maximize sound output relative to size. This specific variant represents a standard general-purpose solution within the manufacturer's audio product portfolio.

Replacement Considerations

Direct substitutes may include other 15mm, 8 Ohm, 300mW miniature speakers from Same Sky or competitors. Verify dimensional compatibility, particularly the 15mm diameter and mounting hole patterns. Ensure equivalent SPL and frequency response characteristics to maintain audio performance integrity in the final application.
