CDS-5085-32-SP

Overview

The CDS-5085-32-SP is a general-purpose round speaker manufactured by Same Sky. It features a 32 Ohm impedance and a rated power of 500 mW, with a maximum power handling of 1 W. The frequency response spans from 400 Hz to 20 kHz, with a self-resonant frequency of approximately 600 Hz. It delivers a sound pressure level (SPL) of 92 dB when tested at 1 W/1m. The unit utilizes a neodymium magnet and a PET cone, with dimensions of 50 mm diameter and 8.5 mm height. Termination is provided via solder pads.

Feature Summary

• Utilizes a neodymium magnet for efficient acoustic performance
• Features a polyethylene terephthalate (PET) cone material
• Designed with top porting configuration
• Supports surface mount or through-hole solder pad termination

Applications

• Portable audio devices
• Medical equipment
• Consumer electronics
• Industrial control panels

Procurement Notes

Verify the specific suffix and packaging format upon ordering, as distributors may list variations such as bulk or tape-and-reel options. Confirm RoHS compliance status and lead times directly with the supplier, as standard delivery periods can fluctuate based on manufacturing schedules. Ensure the selected variant matches the required impedance and power ratings for the target application circuit.

Selection Notes

Select this component when a compact round speaker with high sensitivity is required. The 32 Ohm impedance suits many standard audio amplifier outputs. Consider the 92 dB SPL rating for applications requiring moderate volume levels in small enclosures. Verify that the 50 mm form factor fits within the available chassis space and that the 8.5 mm depth constraint is met.

Part Context

This part belongs to the CDS series of rectangular and round micro-speakers from Same Sky. The series is designed for integration into portable and medical devices where size constraints are critical. The CDS-5085-32-SP represents the round frame variant within this lineup, offering a balance between acoustic output and physical footprint compared to smaller counterparts.

Replacement Considerations

Direct substitutes include other 32 Ohm, 50 mm round speakers from the same manufacturer series, such as the CDS-5085-8-SP (8 Ohm) if impedance matching allows. Cross-brand replacements must match the 50 mm diameter, 8.5 mm height, and 32 Ohm impedance to ensure mechanical and electrical compatibility without redesigning the enclosure or amplifier stage.
