AS02308MR-T

Overview

The AS02308MR-T is a compact electromagnetic speaker transducer manufactured by PUI Audio. It features an 8-ohm impedance and a rated power handling of 1 Watt. The unit has a round shape with a diameter of 22.5 mm and utilizes a Mylar cone material. Key acoustic specifications include a self-resonant frequency of 660 Hz and a sound pressure level of 90 dBA. The device operates within a temperature range of -20°C to +55°C and employs solder pin termination for board mounting.

Feature Summary

• Compact physical design suitable for space-constrained portable electronics
• Electromagnetic transduction mechanism using neodymium magnet structure
• Robust environmental sealing providing protection against dust and water ingress

Applications

• Hand-held electronic devices
• Portable consumer gadgets
• General purpose audio output in compact enclosures

Procurement Notes

Verify the specific suffix designation during procurement, as variations may indicate different packaging or minor manufacturing revisions. Confirm that the solder pin termination style matches the target printed circuit board layout. Ensure the operating environment remains within the specified thermal limits to maintain performance integrity and component longevity.

Selection Notes

Select this component when a balance between low profile dimensions and adequate acoustic output is required for battery-operated systems. The 8-ohm impedance aligns with standard driver outputs, while the 1-watt rating supports moderate volume levels. Consider the IP65 rating if the application demands resistance to incidental moisture exposure.

Part Context

This model belongs to the AS series of general-purpose speakers from PUI Audio. It shares the electromagnetic architecture and Mylar diaphragm construction found across similar compact transducers in the lineup. The series is engineered for high-volume integration into consumer electronics requiring reliable audio feedback.

Replacement Considerations

Direct substitutes include the AST-02308MR-R and AS02308MR-R, which share identical electrical parameters and form factors. Verify that any replacement maintains the same solder pin configuration and mounting footprint to ensure seamless integration without PCB redesign.
