AS07108PO-4-R

Overview

The AS07108PO-4-R is an electromagnetic speaker manufactured by PUI Audio. It features a rectangular shape with dimensions of 71 mm in length, 41 mm in width, and 25 mm in depth. The unit operates at an impedance of 8 Ohms and has a power rating of 6 W. It delivers a sound pressure level of 86 dBA with a resonant frequency of 250 Hz and a maximum frequency response of 20 kHz. The cone material is paper, and the magnet is composed of Aluminum Nickel Cobalt (AlNiCo). Termination is achieved via solder lugs.

Feature Summary

• Utilizes AlNiCo magnetic material for stable electromagnetic performance
• Features a paper cone diaphragm for acoustic output
• Designed with a rectangular form factor for specific enclosure integration
• Equipped with solder lug terminals for direct circuit connection

Applications

• General purpose audio signal reproduction
• Electronic device indicator tones
• Intercom system speakers
• Public address components

Procurement Notes

Verify component authenticity through authorized channels as this part is listed as obsolete. Confirm physical dimensions and terminal compatibility with existing board layouts. Check RoHS compliance documentation for regulatory adherence. Ensure storage conditions protect the paper cone from moisture damage prior to installation.

Selection Notes

Select this component when a rectangular footprint is required for space-constrained designs. Consider the 8 Ohm impedance for matching with standard amplifier outputs. The AlNiCo magnet offers specific thermal characteristics compared to neodymium alternatives. Evaluate the 6 W power handling against expected signal levels to prevent distortion or damage.

Part Context

This model belongs to the AS series of speakers from PUI Audio. It represents a legacy product line utilizing traditional AlNiCo magnets rather than modern rare-earth materials. The rectangular design distinguishes it from the more common round transducers in the same family. It serves as a specialized solution for applications requiring specific mounting geometries.

Replacement Considerations

No public confirmed substitute part numbers are available. As the component is obsolete, engineers must evaluate mechanical fit and electrical parameters of alternative rectangular speakers from current production lines.
