AS05708MR-R

Overview

The AS05708MR-R is an electromagnetic speaker manufactured by PUI Audio, Inc. It features a round shape with a Mylar cone and Neodymium Iron Boron magnet. The unit has an impedance of 8 Ohms and a power rating of 500 mW. Key acoustic parameters include a frequency response centered at 450 Hz and a sound pressure level of 90 dBA. Physical dimensions are 57 mm in diameter and 14 mm in depth. It utilizes solder eyelet termination for board mounting and operates within a temperature range of -20°C to +60°C.

Feature Summary

• Electromagnetic transduction mechanism utilizing a neodymium iron boron magnet assembly
• Mylar cone material construction for diaphragm durability
• Solder eyelet termination style designed for direct board mounting applications

Applications

• General purpose audio indication in electronic devices
• Board-mounted signal alert systems
• Consumer electronics requiring compact electromagnetic speakers

Procurement Notes

Verify the specific suffix configuration against the manufacturer datasheet to ensure compatibility with required electrical characteristics. Confirm that the solder eyelet termination method aligns with the target printed circuit board layout design. Check RoHS compliance documentation for regulatory adherence in the destination market. Ensure operating temperature limits meet the environmental requirements of the final assembly application.

Selection Notes

Select this component when a low-profile electromagnetic speaker with high sensitivity is required for board-level integration. The 8 Ohm impedance matches standard driver outputs. Consider the 500 mW power handling for continuous duty cycles. The Mylar cone offers a balance of cost and performance for general audio tasks. Verify physical clearance for the 57 mm diameter and 14 mm height constraints.

Part Context

This part belongs to the AS series of speakers from PUI Audio, Inc., which focuses on electromagnetic transducers. The series includes various sizes and power ratings. The AS05708MR-R represents a mid-range size option within this lineup, offering higher sensitivity compared to lower-power variants while maintaining a compact form factor suitable for space-constrained designs.

Replacement Considerations

Check for exact pinout and dimension matches if substituting. Verify impedance and power rating compatibility with existing amplifier circuits. Ensure the replacement maintains the same termination type for mechanical stability.
