AS02808MR-R

Overview

The PUI Audio AS02808MR-R is an electromagnetic speaker transducer designed for board mounting applications. It features a round shape with a 28 mm diameter and a height of 5.2 mm. The unit operates with an impedance of 8 Ohms and has a power rating of 1 W. It delivers a sound pressure level of 80 dBA at a resonant frequency of 500 Hz. The cone material is Mylar, supported by a Neodymium Iron Boron (NdFeB) magnet. Electrical connections are made via solder pads. The component functions within a temperature range of -20 C to +60 C.

Feature Summary

• Utilizes a neodymium iron boron magnetic structure for efficient audio conversion
• Features a Mylar diaphragm for consistent acoustic performance
• Designed for direct surface-mount integration using solder pad terminations

Applications

• Consumer electronics audio output modules
• Industrial control panel signaling devices
• Portable electronic device speakers

Procurement Notes

Verify the specific suffix configuration against the manufacturer datasheet to ensure compatibility with required termination styles and environmental ratings. Confirm RoHS compliance status through official documentation before integration. Cross-reference the part number with current engineering change notices to validate any recent design modifications or material updates that may affect mechanical fit or electrical characteristics.

Selection Notes

Select this component when a compact 28 mm round speaker is required for low-power audio applications. The 8 Ohm impedance suits standard driver circuits without complex matching networks. Ensure the enclosure allows for adequate acoustic coupling given the 5.2 mm depth constraint. Consider the Mylar cone material properties regarding thermal stability and frequency response requirements for the specific application environment.

Part Context

This model belongs to the AS series of electromagnetic transducers from PUI Audio. The series offers various sizes and configurations for different audio needs. The AS02808MR-R specifically targets applications requiring a balance between size constraints and moderate sound output levels. It represents a standard solution for general-purpose audio indication in compact electronic assemblies.

Replacement Considerations

Direct substitutes include the AS03008MR-R for slightly larger footprint options or the AS01308MR-R for smaller form factors. Verify dimensional tolerances and terminal placement when swapping models to ensure PCB compatibility.
