AST-01508MR-R

Overview

The AST-01508MR-R is an electromagnetic speaker manufactured by PUI Audio, Inc. It features a round shape with a top port design and utilizes a Neodymium Iron Boron (NdFeB) magnet. The diaphragm is constructed from Polyethylene Terephthalate (PET). This component has an impedance of 8 ohms and a power rating of 1.2 watts, with a maximum power handling capacity of 1.8 watts. It delivers a sound pressure level of 88 dB and operates within a frequency range of 900 Hz to 12 kHz. The self-resonant frequency is specified at 900 Hz. Physically, the unit measures 15.00 mm in diameter and has a maximum height of 4.40 mm. It is designed for board mount installation via solder pads.

Feature Summary

• Top port acoustic design for directional sound projection
• Polyester (PET) cone material for durability
• Neodymium magnet structure for efficient performance

Applications

• Electronic device audio output
• Board-mounted signal indication
• Compact consumer electronics enclosures

Procurement Notes

Verify the exact part number against official manufacturer documentation before procurement, as the AS series nomenclature may vary slightly across distributors. Confirm that the specific suffix matches the required top-port configuration and PET cone material. Ensure compatibility with the target PCB layout for solder pad mounting. Check current availability status as this component may be subject to production lifecycle changes or discontinuation notices. Validate RoHS compliance requirements if applicable to your manufacturing standards.

Selection Notes

Select this model when a compact 15mm diameter speaker is required for applications needing moderate sound pressure levels. The 8-ohm impedance suits standard driver circuits without complex matching networks. Consider the top-port orientation for unobstructed acoustic paths in tight enclosures. Evaluate the 1.2W power rating against peak audio demands to prevent thermal damage. Compare physical dimensions against available space constraints due to the 4.40mm height limit.

Part Context

This component belongs to the AS series of speakers from PUI Audio, Inc., which focuses on electromagnetic transducers for various electronic applications. The series includes models with different diameters, impedances, and power ratings. The AST-01508MR-R specifically represents a mid-range option in terms of size and output capability within this product line.
