AS01504MR-R

Overview

The AS01504MR-R is an electromagnetic speaker manufactured by PUI Audio, Inc. It features a round shape with a diameter of 15 mm and a depth of 2 mm. The component has an impedance of 4 Ohms and a power rating of 200 mW. Its self-resonant frequency is specified at 1.05 kHz, producing a sound pressure level of 86 dBA. The cone material is Mylar, and the magnet utilizes Neodymium Iron Boron (NdFeB). Electrical connection is provided via solder pads, suitable for board mount installation. The operating temperature range extends from -20°C to +55°C.

Feature Summary

• Electromagnetic transducer design utilizing neodymium iron boron magnets
• Compact rectangular form factor with Mylar cone construction
• Direct solder pad termination for printed circuit board integration

Applications

• Consumer electronics audio output
• Industrial control panel indicators
• Medical device alert systems

Procurement Notes

Verify the exact part number against manufacturer documentation, as standard series naming conventions may vary slightly between distributors. Confirm RoHS compliance status directly with the supplier or official datasheet before finalizing procurement. Ensure that the solder pad configuration matches the target PCB footprint requirements. Cross-reference the specific suffix codes if available in official catalogs to guarantee correct electrical parameters and mechanical dimensions are obtained for the production environment.

Selection Notes

Select this component when a low-profile, high-efficiency indicator is required within tight spatial constraints. The 4 Ohm impedance suits direct drive applications from common logic levels or amplifiers. The 86 dBA output provides adequate audibility for close-range alerts. Consider the Mylar cone material properties for cost-sensitive designs requiring reliable performance in moderate temperature environments without specialized acoustic enclosures.
