AS04008MS-R

Overview

The AS04008MS-R is an electromagnetic speaker manufactured by PUI Audio, designed for board mounting applications. It features a round shape with a 50 mm diameter and a depth of 12 mm. The unit operates at an impedance of 8 Ohms and has a power rating of 1.5 W. Key acoustic specifications include a resonant frequency of 800 Hz and a sound pressure level of 85 dBA. It utilizes a Mylar cone and Neodymium (Nd) N35 magnet material. The component supports solder eyelet termination and functions within a temperature range of -25°C to +60°C.

Feature Summary

• Utilizes a Mylar cone diaphragm for audio transduction
• Incorporates a Neodymium (Nd) N35 magnetic structure
• Designed for direct board mounting via solder eyelets

Applications

• Electronic device audio output
• Industrial control panel indicators
• Consumer appliance signaling

Procurement Notes

Verify the specific suffix configuration against the manufacturer's current datasheet to ensure compatibility with required environmental ratings and terminal types. Confirm that the 1.5 W power handling aligns with the target circuit's output capabilities. Check for RoHS compliance documentation if restricted substances are mandated for the final assembly. Ensure mechanical dimensions fit the designated PCB footprint and enclosure space.

Selection Notes

Select this model when a compact, round electromagnetic speaker with moderate power handling is required. The 8 Ohm impedance suits standard amplifier outputs. The Mylar cone offers a balance of cost and performance for general-purpose audio. Consider the operating temperature range of -25°C to +60°C for environmental suitability. The board mount style simplifies integration into rigid assemblies without additional framing.

Part Context

This component belongs to the AS series of speakers from PUI Audio, which focuses on compact electromagnetic transducers. The series includes various shapes and sizes to accommodate different spatial constraints in electronic devices. The AS04008MS-R specifically addresses needs for round, board-mounted solutions with neodymium magnets.

Replacement Considerations

Consult PUI Audio official documentation for verified cross-reference part numbers. Ensure any substitute matches the 8 Ohm impedance, 1.5 W power rating, and 50 mm diameter. Verify terminal type compatibility, as solder eyelets differ from solder pads or screw terminals.
