ADS-2908

Overview

The ADS02908MR-R is an electromagnetic speaker transducer manufactured by PUI Audio. It features a round polyester cone and ferrite magnet, designed for board mount SMD/SMT installation. The unit operates within a frequency range of 750-4000Hz with a self-resonant frequency of 650 Hz. Key electrical parameters include an impedance of 8 Ohms, a power rating of 100 mW, and a sound pressure level of 88 dBA. Physical dimensions are 29 mm in diameter and 9.5 mm in height, with an operating temperature range from -20 C to +55 C.

Feature Summary

Electromagnetic transduction mechanism utilizing a polyester cone and ferrite magnet
Surface-mount technology (SMD/SMT) termination for automated board assembly
Compact circular form factor suitable for space-constrained electronic enclosures

Applications

Consumer electronics audio output
Industrial control panel signaling
Medical device acoustic indicators

Procurement Notes

Verify the specific suffix MR-R against official datasheets to confirm surface-mount compatibility and material specifications. Ensure PCB footprint designs align with the manufacturer's recommended land pattern for reliable soldering. Confirm RoHS compliance status through current regulatory documentation before integration into restricted substance-controlled products.

Selection Notes

Select this component when low-profile surface-mount mounting is required for high-frequency audible signals. The 8-ohm impedance matches standard driver outputs, while the 100 mW rating suits low-power indicator applications. Consider the 29 mm diameter constraint during mechanical layout planning.

Part Context

This part belongs to the ADS series of speakers and transducers from PUI Audio. The series includes various electromagnetic drivers optimized for different mounting styles and acoustic requirements. This specific model represents the compact, surface-mount variant within that product family.
