CDS-1328-16-SP

Overview

The CDS-1328-16-SP is a general-purpose electromagnetic speaker manufactured by Same Sky. It features a 13 mm round frame with a depth of 2.8 mm and utilizes a Neodymium magnet. The unit has an impedance of 16 Ohms, a power rating of 0.2 W (200 mW), and operates within a frequency range of 880 Hz to 5 kHz. The self-resonant frequency is approximately 1100 Hz. It employs solder pads for termination and uses a PET cone material.

Feature Summary

• Compact rectangular design suitable for space-constrained applications
• Utilizes neodymium magnetic structure for efficient sound generation
• Features top porting configuration for direct acoustic output

Applications

• Portable electronic devices requiring low-power audio output
• Industrial control panels and instrumentation
• Consumer electronics with limited internal volume

Procurement Notes

Verify the specific suffix and packaging details against the manufacturer's latest datasheet before ordering. Confirm that the 16 Ohm impedance and 0.2 W power rating align with your amplifier or driver circuit capabilities. Ensure the solder pad termination method matches your PCB assembly process. Check for any recent RoHS compliance updates or alternative package options if required by your supply chain standards.

Selection Notes

Select this component when a small form factor is critical and high fidelity is not the primary requirement. The 16 Ohm impedance may require specific driving considerations compared to standard 4 Ohm speakers. Evaluate the 880 Hz lower frequency limit to ensure it meets the application's bass response needs. Consider the 2.8 mm height constraint during mechanical enclosure design to ensure proper fitment without interference.

Part Context

This part belongs to the CDS series of miniature speakers from Same Sky. These components are designed for integration into compact electronic systems where size and weight are limiting factors. The series offers various impedances and power ratings to suit different audio drive requirements while maintaining a consistent physical footprint for modular design flexibility.

Replacement Considerations

Direct substitutes must match the 13 mm diameter, 2.8 mm height, and 16 Ohm impedance. Verify that alternative models support the same 0.2 W power handling and similar frequency response characteristics. Ensure the mounting configuration and terminal type are compatible with existing PCB layouts.
