AS03604MR-R

Overview

The AS03604MR-R is an electromagnetic speaker manufactured by PUI Audio, Inc. It features a round shape with a 36 mm external diameter and operates at an impedance of 4 ohms. The unit has a nominal power rating of 1 W and delivers a sound pressure level of 83 dBA. Its frequency response ranges from 550 Hz to 11 kHz, with a self-resonant frequency of 550 Hz. The component utilizes a Neodymium Iron Boron (NdFeB) magnet and a Mylar cone. It is designed for board mount installation with top porting.

Feature Summary

• Electromagnetic transducer design utilizing Neodymium Iron Boron magnets
• Top porting configuration for directional sound output
• Round form factor suitable for compact board mounting

Applications

• General purpose audio signaling in embedded systems
• Microcontroller-based electronic devices requiring audible feedback
• Consumer electronics with limited space constraints

Procurement Notes

Verify the specific suffix and revision code against the manufacturer's current datasheet to ensure compatibility with your design requirements. Confirm that the 4-ohm impedance matches your amplifier or driver circuit specifications. Check RoHS compliance documentation if environmental regulations apply to your production region. Ensure the board mount footprint aligns with your PCB layout guidelines before finalizing procurement.

Selection Notes

Select this component when a low-profile, general-purpose speaker is required for applications needing moderate sound pressure levels. The 4-ohm impedance suits circuits designed for lower voltage operation or specific current limits. Consider the 36 mm diameter and top porting orientation during mechanical enclosure design to ensure proper acoustic performance and physical clearance on the printed circuit board.

Part Context

This part belongs to the AS series of speakers from PUI Audio, Inc., which are characterized by their electromagnetic construction and use of NdFeB magnets. The series offers various impedances and power ratings tailored for different audio signaling needs. The AS03604MR-R specifically targets applications requiring a balance between size, efficiency, and cost-effectiveness for standard audio output tasks.

Replacement Considerations

The AS03604MR-2-R is a related variant within the same product family, offering similar dimensions but differing in power rating and frequency response characteristics. Verify electrical parameters and mechanical fit before substitution.
