AS03008MR-R

Overview

The AS03008MR-R is an electromagnetic speaker manufactured by PUI Audio, designed for board mount applications. It features a round shape with a 30 mm diameter and a height of 5.2 mm. The unit operates at an impedance of 8 Ohms with a power rating of 500 mW. Key acoustic parameters include a resonant frequency of 650 Hz, a self-resonant frequency of 500 Hz, and a sound pressure level of 82 dBA. The cone material is Mylar, supported by a Neodymium Iron Boron (NdFeB) magnet. Electrical connections are made via solder pads, and the device functions within a temperature range of -20°C to +60°C.

Feature Summary

• Utilizes a Neodymium Iron Boron magnet for efficient electromagnetic transduction.
• Features a Mylar cone for durable audio reproduction.
• Designed for direct board mounting using solder pad terminations.

Applications

• Consumer electronics audio output
• Industrial control panel indicators
• Medical device signaling

Procurement Notes

Verify the specific suffix and manufacturer part number against official datasheets to ensure correct impedance and terminal configuration. Confirm RoHS compliance status through current regulatory documentation. Check for any recent design changes or obsolescence notices from PUI Audio prior to finalizing procurement orders.

Selection Notes

Select this component when a compact, low-power electromagnetic speaker is required for board-level integration. The 8-ohm impedance and 500 mW rating suit low-voltage battery-operated systems. Ensure the enclosure allows for adequate acoustic coupling given the 30 mm diameter and 5.2 mm depth constraints.
