CDMG15008-03

Overview

The CDMG15008-03A is a miniature electromagnetic 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 device utilizes a Neodymium Iron Boron (Nd-Fe-B) magnet and a Polyethylene Imide (PEI) cone. Its frequency response ranges from 900 Hz to 20 kHz, with a resonant frequency typically between 720 Hz and 1080 Hz. The unit delivers a sound pressure level of 92 dBA at 300 mW/100mm. Dimensions are approximately 15 mm in diameter and 2.8 mm in height, designed for top-port mounting via solder pads.

Feature Summary

• Utilizes a high-strength neodymium magnet for efficient acoustic output in a compact form factor.
• Features a polyethylene imide cone material for durability and consistent performance.
• Designed for board-mount installation with solder pad termination.
• Optimized for general-purpose audio applications requiring low profile dimensions.

Applications

• Portable electronic devices
• Medical equipment audio indicators
• Consumer electronics speakers
• Industrial control panel alerts

Procurement Notes

Verify the exact suffix against official documentation, as variants like CDMG15008-03A specify the 300 mW rating and PEI cone. Confirm dimensional tolerances and resonant frequency ranges required for your specific enclosure design. Ensure soldering parameters comply with thermal limits for the terminal pads. Cross-reference the manufacturer's latest datasheet for any updates on material composition or RoHS compliance status before finalizing procurement.

Selection Notes

Select this component when space constraints require a 15 mm diameter speaker with a height under 3 mm. Choose based on the need for 8 Ohm impedance matching with standard amplifier outputs. Consider the 92 dBA sensitivity for applications requiring moderate volume without excessive power consumption. Verify that the 900 Hz lower frequency limit meets the audio reproduction requirements of the target application.

Part Context

This part belongs to the Same Sky CDMG series of miniature speakers. The series is characterized by low-profile designs suitable for tight spaces. The CDMG15008-03A specifically denotes the 15 mm frame size, 8 Ohm impedance, and general-purpose classification within the manufacturer's audio product lineup.

Replacement Considerations

Direct substitutes may include other 15 mm, 8 Ohm, 300 mW miniature speakers from Same Sky or competitors. Verify mechanical fit, including the 9.2 mm panel cutout requirement. Ensure electrical compatibility regarding impedance and power handling. Check if alternative parts offer similar sensitivity and frequency response characteristics.
